Hey all,

is there a way on iOS to export a SciChartSurface to a vector format in order to embed the exported chart into a PDF document? Right now the only thing I can find in the Documentation is exportToUIImage(). If not – any ideas for a workaround until such feature is implemented?

Hello Team,

I am evaluating Sci Chart for using in our production applications. I am creating a POC for the same if it fits our requirements.

I have created a scattered chart successfully. Our next requirement is to select a part of the chart, basically, like data from this date to this date. I was trying to explore VerticalSlice Modifier for it. My purpose was that the user will place the sliders on the start date and end date and we will get those values. Can you tell me if this approach is correct or suggest a different technique, annotation or marker, any other modifier to select data between two dates?

<Grid Grid.Row="1">
        <s:SciChartSurface s:ThemeManager.Theme="BrightSpark">
            <s:SciChartSurface.ChartModifier>
                <s:ModifierGroup>
                    <s:VerticalSliceModifier Name="sliceModifier">
                        <s:VerticalSliceModifier.VerticalLines>
                            <s:VerticalLineAnnotation X1="{Binding SelectedStartDate, Mode=TwoWay}" IsEditable="True"/>
                            <s:VerticalLineAnnotation X1="{Binding SelectedEndDate, Mode=TwoWay}" IsEditable="True"/>
                        </s:VerticalSliceModifier.VerticalLines>
                    </s:VerticalSliceModifier>
                </s:ModifierGroup>
            </s:SciChartSurface.ChartModifier>
            <s:SciChartSurface.XAxis>
                <s:DateTimeAxis AxisTitle="Number of Samples (per Series)"/>
            </s:SciChartSurface.XAxis>
            <s:SciChartSurface.YAxis>
                <s:NumericAxis AxisTitle="Value"/>
            </s:SciChartSurface.YAxis>
            <s:SciChartSurface.RenderableSeries>
                <s:XyScatterRenderableSeries x:Name="scatterSeries" Stroke="OrangeRed" DataSeries="{Binding Chirps}">
                    <s:XyScatterRenderableSeries.PointMarker>
                        <s:EllipsePointMarker Width="9" Height="9" Fill="SteelBlue" Stroke="LightSteelBlue" StrokeThickness="2"/>
                    </s:XyScatterRenderableSeries.PointMarker>
                </s:XyScatterRenderableSeries>
            </s:SciChartSurface.RenderableSeries>
        </s:SciChartSurface>
    </Grid>

Hi,

I tried submitting a priority support ticket but I always get a 500 error after submitting.

I have an issue with a realtime graph tick label. The “zero” label sometimes changes to a strange value (-5.5511E-17) for no reason.

This only happens when the graph is running in a 32bit process, I can’t replicate it when running at 64bit.

Some info:

No operations on the labels in the code-behind

Data is stored in a XyDataSeries<double,double>


The issue is visible in the video and the image called “G5”. Image “Hashes” shows the alternative text formatting option of “#.#####” which doesn’t show a “0” value at all.
I can write a workaround, but I would like to know if this is a known issue or there is something wrong with my settings.

Video here: https://youtu.be/OGaAOVe9Yew

Thank you

Hi,

I am using .NET 4.0 and SciChart v4.2.6.11205.

I have a viewmodel with the following property:
public AnnotationCollection Annotations { get; set; }

I have tried binding to the Annotations property from my view with the following code but without success:
Annotations=”{Binding Annotations}”
Annotations=”{Binding Path=Annotations}”

How to I bind to an AnnotationsCollection with SciChart 4.0?

Do you have an example you can send me.

Hello,

I’m trying to drag several VerticalLineAnnotationViewModel simultaneously. So if I drag one all other should move the same delta.
I subscribed the “DragDelta”-Event for each VerticalLineAnnotationViewModel. My problem is that “AnnotationDragDeltaEventArgs” seems in pixel unit and I didn’t find a CoordinateCalculator for the NumericAxisViewModel. Is there any solution to convert the dragged delta to dataValue or axis coordinates so I could just add the delta to the X1 property of my VerticalLineAnnotationViewModels?

Hello,

I am using mountain chart to draw some data. First time open the chart screen, the graph plots properly. If we do scroll forward the graph x-axis last label is missing. If we do scroll backward the graph x-axis first label is missing.

Here I have attached working .swift file.

Note: We are using mountain chart with multiple line series. We are not using stacked mountain chart.

Hello,

I am creating a LineAnnotation using Annotation Modifier.

In AnnotationCreated event, I need the Hit Test Info of the start and end Points of annotation i.e. annotation.X1,Y1,X2,Y2 points in order to find out the series name and other information(similar to HitTestAPI example in examples suit).

I also need to verify if they are lying on a series or not.

The problem here is series.HitTest() accepts a raw point which I am unable to get from annotation.

Is there any way to do this.

Hi,

we have a graph which it’s x axis visible range changed when the graph draw until the max (as a travel graph)
we also have logic for each serie a minimum\maximum range, outside of this range the color should be red
so, we use the ExtremePointMarkerPaletteProvider and set for each value the suttible color in the colors list.

our problem is when the graph visible range changed – the serie points is draw correctly but it’s color is not match.
the colors are stay the same as they was before the range changed.
we looked at the colors list and YValues list – the value and the color on each index was match.
the problem is only in the view.

also, after some time it’s fixed, we don’t know what cause it to be fixed…

Thanks

Hi,

every time we update the chart, the lines jump around and it seems we need to have a delay before calling zoomExtents() for it to work properly – but even with 500ms delay, zoomExtents still does not work always (see 0:27 of below video- what helped was manually moving the chart). We want a smooth transition when changing timescale. My guess is we are misusing the library somehow, but after thorough reading through the docs we could still not fix this.

Here is a video showcasing this problem:

https://screencast-o-matic.com/watch/cqiUjxOkV6

Here is the code that updates the surface. Basically we clear the Renderable Series of surface before we show new data. Full code where we make charts (on each update) is seen here:

// OHLC Chart Data
ohlcData.append(ohlcSeries.getDateData(), ohlcSeries.getOpenData(), ohlcSeries.getHighData(), ohlcSeries.getLowData(), ohlcSeries.getCloseData());

// Bollinger Upper Band
XyDataSeries<Date, Double> bollUpper = sciChartBuilder.newXyDataSeries(Date.class, Double.class).withSeriesName("BBU").build();
bollUpper.append(ohlcSeries.getDateData(), upperBB_data);
BaseRenderableSeries seriesBBU = sciChartBuilder.newLineSeries().withDataSeries(bollUpper).withStrokeStyle(Color.rgb(70,130,180), 1f).withYAxisId(PRICES).build();
seriesBBU.setClipToBounds(true);

//* ... some more lines and indicators built here ... */

// clear surface on update
if(!surfaceOhlc.getRenderableSeries().isEmpty())
    surfaceOhlc.getRenderableSeries().clear(); 

// create series
seriesMA.setIsVisible(SharedPreferencesInstance.getBoolean("advanced_chart_show_ma", true));
seriesEMA.setIsVisible(SharedPreferencesInstance.getBoolean("advanced_chart_show_ema", true));
seriesBBU.setIsVisible(SharedPreferencesInstance.getBoolean("advanced_chart_show_boll", true));
seriesBBL.setIsVisible(SharedPreferencesInstance.getBoolean("advanced_chart_show_boll", true));
seriesBBM.setIsVisible(SharedPreferencesInstance.getBoolean("advanced_chart_show_boll", true));

surfaceOhlc.getRenderableSeries().add(sciChartBuilder.newCandlestickSeries().withDataSeries(ohlcData).withSeriesInfoProvider(new CustomOHLCSeriesInfoProvider()).withYAxisId(PRICES).build()); // todo : setClipToRounds(true)
surfaceOhlc.getRenderableSeries().add(seriesBBU);
surfaceOhlc.getRenderableSeries().add(seriesBBL);
surfaceOhlc.getRenderableSeries().add(seriesBBM);
surfaceOhlc.getRenderableSeries().add(seriesEMA);
surfaceOhlc.getRenderableSeries().add(seriesMA);

surfaceOhlc.getAnnotations().add(annPrice);

Hello,

I am adding a line annotation using annotation modifier, and it works perfectly fine.

But the problem is, I want to restrict the creation when the start and end points of annotation are not part of a line. I don’t care if they are not part of dataseries points, user can select any point on the line.

I am unable to find a way to verify this. Can you look into this.

Hello.
I am working on a stock chart with socket.
When received a new data, it is added to the chart,
but the labels of xAxis do not update their datetimes.
And I touch the surface of the chart,
then the labels of xAxis are updated.
What is wrong?
I attach some parts of my code.
Please let me know the correct way that I can update automatically the labels of x axis when a new data is added to.

The function for the x Axis creation
void setYAxis() {
yAxis = sciChartBuilder.newNumericAxis().withGrowBy(0d, 0.1d).withAxisAlignment(AxisAlignment.Right).withAutoRangeMode(AutoRange.Always).build();

    PenStyle tickStyle = new SolidPenStyle(_chartSetting.tickStyle, true, 2, null);
    BrushStyle bandStyle = new SolidBrushStyle(_chartSetting.bandStyle);
    PenStyle gridlineStyle2 = new SolidPenStyle(_chartSetting.gridlineStyle2, true, 2, null);
    // PenStyle gridlineStyle = new SolidPenStyle(_chartSetting.gridlineStyle, true, 1, new float[]{10, 10});
    PenStyle gridlineStyle = new SolidPenStyle(_chartSetting.gridlineStyle, true, 1, null);

    yAxis.setAxisBandsStyle(bandStyle);
    yAxis.setDrawMajorBands(true);
    //yAxis.setMinorTickLineStyle(tickStyle);
    yAxis.setMajorTickLineStyle(tickStyle);


    yAxis.setMajorGridLineStyle(gridlineStyle);
    yAxis.setMinorGridLineStyle(gridlineStyle2);
    String yFormat = "%.2f";
    if (chartData != null) {
        SmSymbolManager symbolManager = SmSymbolManager.getInstance();
        SmSymbol symbol = symbolManager.findSymbol(chartData.symbolCode);
        yFormat = "%.";
        if (symbol != null)
            yFormat += Integer.toString(symbol.decimal);
        else
            yFormat += Integer.toString(2);
        yFormat += "f";
    }
    yAxis.setLabelProvider(new NumericLabelProviderEx(yFormat));

    Collections.addAll(surface.getYAxes(), yAxis);

    if (_style == "mock_left" || _style == "mock_right") {
        yAxis.setVisibility(View.GONE);
    }

    if (_style == "mock_main") {
        yAxis.setVisibility(View.VISIBLE);
        yAxis.setAxisAlignment(AxisAlignment.Left);
    }
}

The callback function for the new data arrival.
private synchronized Action1 onNewPrice() {

            //Log.d("TAG", "onNewPrice:  -> " + price.getSymbolCode() + "::" + strDate);

            if (getSeriesType() == SmSeriesType.CandleStick || getSeriesType() == SmSeriesType.Ohlc) {
                ((IOhlcDataSeries) dataSeries).append(price.getDate(), price.getOpen(), price.getHigh(), price.getLow(), price.getClose());
            } else {
                ((IXyDataSeries) dataSeries).append(price.getDate(), price.getClose());
            }

            IRange dataRange = xAxis.getDataRange();

            final IRange visibleRange = surface.getXAxes().get(0).getVisibleRange();
            if (visibleRange.getMaxAsDouble() > dataSeries.getCount()) {
                visibleRange.setMinMaxDouble(visibleRange.getMinAsDouble() + 1, visibleRange.getMaxAsDouble() + 1);
                xAxis.updateAxisMeasurements();
            }

            getActivity().runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    ohlcAxisMarker.setBackgroundColor(price.getClose() >= price.getOpen() ? STOKE_UP_COLOR : STROKE_DOWN_COLOR);
                }
            });

            //smaAxisMarker.setY1(smaLastValue);

I want to made custom verticalLine extension which drag to series point. I use MVVM pattern. I made a custom VerticalLine from VerticalLineAnnotationViewModel. I set X1 value from model then the position of line chaning, then I drag the line with mouse. I get the earlier value of X1 in the DragSarted event, not that value which I set in model.
How can I gat correct value from DragStart?
I found similar problem in forum https://www.scichart.com/questions/wpf/problem-setting-a-vertical-line-annotation-position-in-mvvm

I made wpf project with MVVM. I added LineRenderableSeriesViewModel to the model. SelectedSeriesStyle contains StrokeThickness=3 property. When I click on series, the SeriesSelectionModifier set correctly the line thicknes, but when I set IsSelected property in model, the seriesline thickness not changing. The stroke and PointMarkerTemplate properties work correctly.
Why not changing StrokeThickness property by model?

Hi,

this is my scenario: I want to create a “band annotation”, a stretched box with some text.
I can use Text annotation but I want that annotation stretch in some directions.

In example, X1 = extreme left (as X1=0 in relative mode), X2 = Some X Axis Value, Y1 = Some Y Axis Value, Y2= Some Y Axis Value. This is a band without definite X1 value.

Or: X1 = Some axis value, Y1 = Some Axis Value, X2 = extreme right, Y2=Extreme Bottom, this is a rectangle that stretch to the bottom right corner.

At the end I must place a text in the center of box.

Can you help me?

Thank’s
marc.

I was looking at the example given at this link for NonUniformHeatmapDataSeries in SciChart. In this example, the width and height of heatmap is given as h=4 and w=7. As I understand h is for Y axis and w is for X axis and data[,] is for Z axis. However, the counts in actual data filled for these axis are not matching wight h and w.

var xRangeMapping = new int[] { 0, 10, 20, 26, 36, 60, 72, 84 };   // 8 points for w
var yRangeMapping = new int[] { 100, 250, 390, 410, 600 };         // 5 points for h

What is the purpose of extra points added at first place (0 and 100)? Are these required to set the starting point for both axis?

Here is the code given at above link:

int w = 7, h = 4;
var data = new double[h, w];
double maxValue = double.MinValue;
for (int x = 0; x < w; x++)
    for (int y = 0; y < h; y++)
    {
        data[y, x] = 3.5 * ((h - y) * (w - x));
        maxValue = Math.Max(maxValue, data[y,x]);
    }
var xRangeMapping = new int[] { 0, 10, 20, 26, 36, 60, 72, 84 };
var yRangeMapping = new int[] { 100, 250, 390, 410, 600 };
var heatmapDataSeries = NonUniformHeatmapDataSeries<int, int, double>(data, i => xRangeMapping[i], i => yRangeMapping[i]);

// Apply the Heatmap DataSeries to a FastNonUniformheatmapRenderableSeries
var heatmapRenderableSeries = new FastUniformHeatmapRenderableSeries()
 {      
     ColorMap = new HeatmapColorPalette()
    {
        Maximum = maxValue,
        Minimum = 0,
        GradientStops = // exercise left to the reader
    }
 };

How to make chart axis (date axis in my case) to move with scrolling?

Because currently labels staying on it’s positions and just refreshing its values.

let xAxis = SCIDateTimeAxis()
xAxis.axisId = ChartWrapper.SURFACE_MAIN_X_AXIS_ID
xAxis.autoRange = .never
xAxis.visibleRange = sharedXRange
xAxis.style.drawMajorBands = false
xAxis.style.drawMajorTicks = false
xAxis.style.drawMinorTicks = false
xAxis.style.drawMinorGridLines = true
xAxis.textFormatting = "HH:mm:ss"
xAxs.style.drawLabels = true

We have a graph surface with some point markers on it and we want to show a custom tooltip every time the user taps on a point marker. So far I’ve used a UITapGestureRecognizer, convert the touchpoint in the chart frame and for each of the renderable series perform a HitTestAtX with a radius (I’ve tried 1, 5 and 30) but it always returns true, even if I tap on an area where there’s a gap in the chart. Here’s some sample code:

SCIHitTestInfo hitTestInfo = renderableSeries.HitTestProvider.HitTestInterpolateModeAtX(touchPoint.X, touchPoint.Y, 30, renderableSeries.CurrentRenderPassData);

if (hitTestInfo.match)
{
       Console.WriteLine($"Tapped {hitTestInfo.xValue} {hitTestInfo.yValue} with index {hitTestInfo.index} of the series {renderableSeries.DataSeries.SeriesName}");

       var elementSeries = Model.BottomRightLegendList.FirstOrDefault(tup => tup.DataSeries.SeriesName == renderableSeries.DataSeries.SeriesName);

       var element = elementSeries.GraphElement;

       if (element != null)
       {
            matchedElements.Add(element);
       }
}

Why is the “match” property always true, even if there are no Point Markers in the radius?

Hi

I have a SCIFastLineRenderableSeries backed by data in SCIXyDataSeries.

I setup FIFO to 300 (this just a number I may increase, but it stores 30+ seconds of data)

x data is time stamp.

each time I have new data, I set a new visibleRange to show about 30 seconds of data on screen

xAxis.visibleRange = [[SCIDoubleRange alloc] initWithMin:SCIGeneric(secondSinceStart-31) Max:SCIGeneric(secondSinceStart)];

So this will scroll along showing latest 30 seconds of data. And that’s great.

But I want to scroll to the left to view the older data. because of the visibleRange is set I am not able to touch the axis labels and do anything)

how do I set the visibleRange or maybe not set it, so I can enable the scroll.

Here is the drag modifier I use , but I think it does not do anything either because of the visibleRange
SCIXAxisDragModifier * xAxisDragmodifier = [SCIXAxisDragModifier new];
xAxisDragmodifier.dragMode = SCIAxisDragMode_Pan;
xAxisDragmodifier.clipModeX = SCIClipMode_None;

Thanks

I am using a custom CursorModifier class in my WPF code. I have created a class inherited from CursorModifier for this purpose. Now I want to apply cross-hair cursor style to my chart. The style in XAML is not getting applied at all. However, when I use the CursorModifier directly (instead of custom modifier class) in XAML, then it applies.

If I changed the TargetType to “loca:MyCursorModifier”, then it gives error “The memeber StrokeThickness is not recognized” & “The “memeber Stroke is not recognized”.

<UserControl.Resources>
    <Style x:Key="CrossLineStyle" TargetType="Line">

i want to implement a custom modifier to track the users touch, similar to rollover but without displaying a view

I tried to do this by implementing SCIGestureModifier and overriding all the onTouches methods, but – no matter the user behaviour – the modifier will always receive an onTouchesCancelled event after about a second and receive no more of these events after that.

What does work is implement onPanGesture to actually track all the user’s movement but i don’t see any way of how you would receive a touch up event this way (which i do need)

Is there any fundamental misunderstanding on how this should work on my side?

So for both SCIZoomPanModifier and SCIXAxisDragModifier you can set a clip mode, that will cause the graph to not zoom in if you try to scroll past the edges.

This is not possible for the y-axis however, so everytime anyone scrolls up or down to far, the graph zooms in, which is not useful to anyone ever

Is there any way to change this behaviour at all?

Thanks in advance

Hi! I’ve purchased your products including source code. I need to modify some of your code and have tried in many ways, but I have not compiled your source codes successfully. I am working on it on my Mac Osx, using android studio version of Android Gradle Plugin Version 3.1.0 and Gradle Version 4.4. I’ve got these errors, but I could not find any hints to solve this problem from your QnA site and google. The messages are following. Please let me know how to compile your source code properly. The source codes I have is SciChart_Android_v2.5.0.2540_SDK. Thank you for your good products and service.

I’m trying to add more intervals into the legend of the Heat map. So far it only displays 10, 8, 6, 4, 2, 0, but I would like to edit it to display the numbers 0-10. From what I understand, the TickProvider API only works with an X or Y axis so I’m not sure if there’s a way to add the function.

I’m using the Ternary Chart to plot three variables of interest.

Technically, a ternary plot should have three variables that sum to a constant.

However, the domain of my variables includes negative values.

Now, in theory, the linear space of the domains of each of the variables could be mapped onto R => [0,100].
From this, we can then compute the sum and normalize each variable by this sum to produce a [0, 100] value for each of the axes.

The problem is, I lose the original domain values prior to the transformation.

So my question is, can I use negative values for the ternary plot?

Thanks.

Hello,
My requirement is to plot 3 dimensional data(x,y,z) in 2 D WPF chart. I know this is possible with bubble chart. But , i would like the plot to be seen as shown in the attached image file. I would like have Crossmark point marker instead of bubble(ellipse marker?) and crossmark should not be scaled according to z value(no scaling of point marker and it should be of default size ).
Please let me know how to achieve this one?

Hi,
I’m using SciChart version 5.1.1.11473, runtime v4.0.30319 and SciChartEx 1.0.0.0.
I am having difficulty using LineArrowAnnotation and I need some help to solve my problem.

My problem is when I use the zoom and the size of the arrows.
When I zoom I need the length of the arrow not to change.
What process do I need to do to make the arrow the same size even when zoomed in?

. Below is a brief explanation of the program.
I made a linear graph where in certain points I show arrows down or up on the screen. (see Image01 below)
enter image description here ( Image01 )

With “HeadLength” and “HeadWidth” I can make the arrow head, the arrow body I am using “Y1” and “Y2”. (see Image02 below)
enter image description here ( Image02 )

When I zoom, I noticed that the arrow head does not change, but the length of the arrow does.
I need this length of arrow not to change like the head of the arrow. (see Image03 below)
enter image description here ( Image03 )

Finally, I apologize for my lack of knowledge of the products of your lordships.
And thanks for the attention paid.
Waiting for an answer.

Hamilton.

Hello,

I recently upgraded from v3 to v5, and I cannot figure out what to replace ToolTipLabelTemplate types with now that it’s missing. I saw in a different question like this that you directed them to look at ToolTipModifier documentation, and I have looked there, but I can’t find anything helpful for this problem. Could you please direct me to an example or explain what to change for a ToolTipLabelTemplate to make it work in v5.

Thanks,
Rachel

Hi, if I have multiple graphs stacking on top of one another, is there any way for me to align them by the Y axis on the left?

I noticed that padding is applied to the most outer edge drawn item, so in many cases that would be the label, not the axis.

Hello,

I am trying to develop a WPF Chart with multiple X and Y Axes. I am able to achieve this perfectly and also I am able to remove a data series using the example available:

WPF Chart Add or Remove DataSeries

But, I am unable to remove the corresponding axes of the series whenever it is removed.

I am using the same logic used to remove a series:

sciChart.XAxes.Remove(sciChart.XAxes.GetAxisById(sampleId));

But, I am unable to get the expected result.

Am I missing something?

Hello.

It’s very strange, but chart can not be zoomed with pinch, only by double tap fitting full screen.
And when trying to zoom app freezes and CPU load became 100%.

func installChart() {

Currently the color of 3D axis plane can only be filled with one color by the property AxisPlaneBackgroundFill. We have a requirement that gradient color should be used there. Is it possible to achieve these through styling or templating, or otherwise? If not, could this possibly be implemented in the future?

Today is my first day using SciChart and I’m following along with this hello world demo –

https://www.scichart.com/documentation/android/v2.x/webframe.html#Tutorial%2002%20-%20Creating%20a%20Chart.html

For some reason Android Studio won’t recognize ‘SciChartBuilder.init(this)’. Am I missing a file? I can create an instance of SciChartSurface with no problem but the builder line is a no-go. I have imported and referenced the 4 correct .aar files in my gradle.build file so I’m not sure what else I’d be missing. Any help for a newbie would be appreciated!!

There is a problem with annotation drag listeners. OnDragEnded and in fact also OnDragStarted are called all the time (just like onDragDelta) instead of only on those particular events

Steps to reproduce
just add a listener to annotation (in my case CustomAnnotation)

.withAnnotationDragListener(object : OnAnnotationDragListener {
            override fun onDragDelta(annotation: IAnnotation, x: Float, y: Float) {
                //whatever
            }

            override fun onDragStarted(p0: IAnnotation?) {
                "onDRAGSTARTED".log()
            }
            override fun onDragEnded(p0: IAnnotation?) {
                "ONDRAGENDED".log()
            }
        })

Is there a solution?

Hi,
Is it possible to append different size of parameters in xyzDataSeries<double,double,double>?
My requirement is to plot a bubble chart where size of X and Z array are same but Y array is of different size.
for ex, i need to append x[10], y[5], z[10] in xyzDataSeries<double,double,double>
please let me know if its possible or not

Hi

I would like to modify the DateTimeAxis to have the date shown static below the time.
Currently I can’t figure out how to code something like that.

The basic idea is to have the date label

a) on the left and right of the date axis and moving with midnight
b) as bar below the time stamp

Is it possible to modify the DateTimeAxis to achieve both use cases?

To visualize, what I’m trying to achieve find some mocks below (neglect the time, midnight just moved to 18:19:30 :-))
