Hi,

I’m currently testing the 3D charts of scichart, if we can use it for our next project. I have to build up a chart, that looks like that attached ref.jpg. I’m currently using the MountainRenderableSeries3D and I get the data displayed in the way it should be, beside the area below the curve (see screenshot.jpg).

Is it possible to fill the area below the curve? Which kind of RenderableSeries3D do I Have to use?

Thanks!

Hello,
Can someone explain how to set SeriesValueModifier.IsSeriesValueModifierEnabled for particular RenderableSeries in code?

I would like to implement a custom DateTime axis LabelProvider with the following behavior:

• Show full date and time at the start of the visible region
• Show only time on all other ticks unless the date changes from the previous tick.

So, an axis might look like:

10/01/2016 23:00 23:30 10/02 00:00 00:30 01:00

It seems this is doable as long as 00:00:00 appears as one of the label values, but I’m not sure l can be guaranteed. It is likely that none of the entries in the series would contain that exact value. One entry might be 23:59:17 and the next 00:01:13.

Is there any way for a LabelProvider to determine what the preceding label value was?

I’m having some difficulty with the RolloverData PropertyChanged notification. I have attached an event handler based on your code, which is triggered as I mouse over the chart, but the SeriesInfo collection always has a count of 0. The data bound rollover block does update correctly.

Any ideas?

In a scenario where two numeric axis (X, Y) both have IsCenterAxis set to true, is it then possible to force MouseWheelZoomModifier to use center point of current view when zooming, rather than using mouse point as center point when zooming ?

Have a look at the example. I’d like to get rid of the brown line between June 10 and 11. Since there’s no day between 10 and 11, I can’t use the draw NaN as gap option here. Or can I?

Thanks,
Ruud

Hi
i have multiple charts. They all bind to the same visiblerange(to be precise: to the same values not the same instance).
But the length of the xaxis are different(see the attached image). The reason is the the big yaxis numbers in the lower chart. But i need them to be aligned. Is there a way to achieve this?
Thanks in advance

Very simply, I am attempting to get the Examples to compile and upload to my Android phone. The first download had the examples, but not including Showcases. That version I successfully compiled and ran on an Android phone. Very happy with the professional look and feel.

Since then, I re-downloaded the examples including Showcase and gone through so many upgrades of Android Studio and Gradle and various supporting libraries (as prompted) I’ve lost track.

However, now I cannot compile. Please tell me what dependency is broken of config needs to be changed. Someone else must have been through this.

Thank you for your help.

Dear all,

I am dynamically changing my series type by switching from Bar, to Line, or to scatter.
Bar and line works perfectly well, but have no idea why nothing gets displayed fore scatter.

Here the code below from your sample where I apply the style :

private IRenderableSeriesViewModel New(Type type, IDataSeries dataSeries = null)
    {
        var xyDataSeries = dataSeries ?? GetXyDataSeries(GetRanromWalk(0));
        if (type == typeof(ColumnRenderableSeriesViewModel))
        {
            return new ColumnRenderableSeriesViewModel {

                DataSeries = xyDataSeries,
                StyleKey = "BarSeriesStyle" };
        }


        if (type == typeof(LineRenderableSeriesViewModel))
        {
            return new LineRenderableSeriesViewModel {
                DataSeries = xyDataSeries,
                StyleKey = "LineSeriesStyle"
            };
        }


        if (type == typeof(XyScatterRenderableSeriesViewModel))
        {
            return new XyScatterRenderableSeriesViewModel {
                DataSeries = xyDataSeries,
                StyleKey = "ScatterSeriesStyle" };
        }

        throw new NotImplementedException("Unsupported Series Type");
    }

And the style named for scatter which is store in application resources, same as other style

<Style x:Key="LineSeriesStyle" TargetType="s:FastLineRenderableSeries">
    <Setter Property="Stroke" Value="DarkBlue" />
    <Setter Property="StrokeThickness" Value="3" />
</Style>

<Style x:Key="BarSeriesStyle" TargetType="s:FastColumnRenderableSeries">
    <Setter Property="Stroke" Value="Orange" />
    <Setter Property="StrokeThickness" Value="3" />
</Style>

<Style x:Key="ScatterSeriesStyle" TargetType="s:XyScatterRenderableSeries">
    <Setter Property="Stroke" Value="Yellow" />
    <Setter Property="PointMarkerTemplate">
        <Setter.Value>
            <ControlTemplate>
                <s:EllipsePointMarker Width="5" Height="5" 
                    Fill="Red" 
                   Stroke="#FF000000"
                   StrokeThickness="2"/>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Any idea what I do wrong ?

Howdy! I’m Ross, and I’ve been trying out SciChart as a replacement for Dynamic Data Display in a program I’m working on. So far, SciChart has better documentation, support, and features, which is great. Once I’m at the level where I was with the previous tool, this will likely be the one I purchase. But there was a good behavior I liked in D3 that I’m struggling to implement in SciChart.

I want the scroll wheel behavior to only zoom on a single axis when the mouse is over that axis. So if I move my mouse over the x-axis and scroll, I want it to only change that axis’ space.

So, for example, “Drawing a line graph” here: http://research.microsoft.com/en-us/um/cambridge/projects/ddd/d3isdk/

I think the key is my inability to find the region that the axes occupy. I know I can trigger on entering or leaving the region to change behavior from there. Is there an easy way to find these values?

If this is in some example I haven’t seen or has been answered before, I’d be appreciative of a link, as well! Thanks!

We are adding 24 channel data Live graph using Scichart Example of Vital sign monitor. We are using VitalSignsMonitorShowcaseFragment.java example.

To show the live graph, do we need to accumulate the data for 50 point or so. I see in the code they are accumulating?

Is it necessary for the accumulation, please let us know

protected void initExample(ExampleVitalSignsMonitorFragmentBinding binding) {
    final DefaultVitalSignsDataProvider dataProvider = new DefaultVitalSignsDataProvider(getActivity());

    setUpChart(dataProvider);

    dataProvider.getData().buffer(50, TimeUnit.MILLISECONDS).doOnNext(ecgData -> {
        if(ecgData.isEmpty()) return;

        dataBatch.updateData(ecgData);

        UpdateSuspender.using(binding.surface, () -> {
            final DoubleValues xValues = dataBatch.xValues;

            ecgDataSeries.append(xValues, dataBatch.ecgHeartRateValuesA);
            ecgSweepDataSeries.append(xValues, dataBatch.ecgHeartRateValuesB);

            bloodPressureDataSeries.append(xValues, dataBatch.bloodPressureValuesA);
            bloodPressureSweepDataSeries.append(xValues, dataBatch.bloodPressureValuesB);

            bloodOxygenationDataSeries.append(xValues, dataBatch.bloodOxygenationA);
            bloodOxygenationSweepDataSeries.append(xValues, dataBatch.bloodOxygenationB);

            bloodVolumeDataSeries.append(xValues, dataBatch.bloodVolumeValuesA);
            bloodVolumeSweepDataSeries.append(xValues, dataBatch.bloodVolumeValuesB);

            final VitalSignsData lastVitalSignsData = dataBatch.lastVitalSignsData;
            final double xValue = lastVitalSignsData.xValue;

            lastEcgSweepDataSeries.append(xValue, lastVitalSignsData.ecgHeartRate);
            lastBloodPressureDataSeries.append(xValue, lastVitalSignsData.bloodPressure);
            lastBloodOxygenationSweepDataSeries.append(xValue, lastVitalSignsData.bloodOxygenation);
            lastBloodVolumeDataSeries.append(xValue, lastVitalSignsData.bloodVolume);
        });
    }).compose(bindToLifecycle()).subscribe();

    updateIndicators(0);
    Observable.interval(0, 1, TimeUnit.SECONDS, AndroidSchedulers.mainThread())
            .doOnNext(this::updateIndicators)
            .compose(bindToLifecycle()).subscribe();
}

Hi,

I am trying to add labels to the x axis but I don’t want the axis line to be visible. numericAxis.drawLabels = true enables the x axis line also. Is there a way to disable it?

I am considering applying server-side licensing for my javerScript application.

In the document below, there is a phrase “Our server-side licensing component is written in C++.”
(https://support.scichart.com/index.php?/Knowledgebase/Article/View/17256/42/)

However, there is only asp.net sample code on the provided github.
(https://github.com/ABTSoftware/SciChart.JS.Examples/tree/master/Sandbox/demo-dotnet-server-licensing)

I wonder if there is a sample code implemented in C++ for server-side licensing.

Can you provide c++ sample code?
Also, are there any examples to run on Ubuntu?

Hello,

How to add buy sell annotation to real time chart(Performance demo chart in examples)

Hello,

I am using the BrushAnnotation and it works fine except that the
mouseover events seems to happen too soon.
I mean that when the mouse is close to the BrushAnnotation, but not on it,
the mouse cursor changed and I can drag the BrushAnnotation.
It happens for all lines but especially for shapes with many segments which
are closed to each other, see attached file ‘MouseOver event too soon (my application).png’.
I saw something similar in your ‘Trade Annotation’ example ,
it happens when I used the Tools=>Pointer, see attached figure ‘MouseOver event too soon (from Scichart example).png’.
Can I changed the distance from which the mouseover event starts?

Best regards,
Eyal

I am using sci charts to show live graphs of some devices. While displaying a graph on IPhone X or iPhone 6s it sometimes lags and lines started overlapping. It’s working fine on devices iPhone XSMax, iPhone 11. I have attached a 3 screenshots. Once when graph starts lagging, 2nd when graph is in middle, 3 when graph completes. please have a look. It starts lagging and overlapping lines when a new graph starts and when it ends it shows a complete graph shown and then again same issue repeats. It also started working correctly after some time. I need information about this issue. How to fix it and why it’s happening like this…

How do you set X1,X2 and Y1,Y2 in xaml as suggested in a previous post here on the forum?

I also get null values here when using Composite Annotations example. the suggestion to set the value DependencyProperty.SetCurrentValue(X1Property, 0.0); does not work since DependencyProperty does not expose a SetCurrentValue method (?)

I am using your example code for doing composite Annotations on my existing chart.
I am using MeasureXAnnotation and MeasureXyAnnotation and the respective Update method that is overidden.

What am I missing ?

Appreciate your help with getting this working

Thanks
Anders

Hi,

to draw a stock bar, the open-close width are auto set according to zoom, which is okay. But the highest-lowest line in the middle of a stock candlestick is too thin.

I’ve been searching for a way to increase the width of the highest-lowest line, but neither the showcases nor the forum provides a solution.

Any help? Thank you.

My MVVM application can display more than 300 FastLineRenderableSeries on a SciChartSurface. SciChart handles the data and redisplays quite well. Thank you!

My users may mouse click on a series and quickly see the SelectedSeriesStyle change. The application needs to access the SeriesName of the SelectedSeries in the ViewModel for updates to other items in the ViewModel.

I read the topic/posts tagged SelectionSeriesModifier MVVM and the SeriesSource API. My attempts to utilize the CollectionChanged event of SelectedRenderableSeries (not in code-behind) have not had any success. It seems that I should do a OneWayToSource binding from SelectedRenderableSeries to an ObservableCollection<IChartSeriesViewModel> in the ViewModel. I would then like to use an MVVM Light EventToCommand bound to the CollectionChanged event.

Can you provide a demo or workaround on how to actually make this work?

Hi,

Our view models currently hold AxisCollection and work with IAxis. We’re hoping to switch to working with IAxisViewModel at this level.
But some feature differences will make this harder:

• IAxis.TickLabelStyle – view model only supports TickTextBrush, not the other font related properties we customise in this style.
• SImilarly MajorGridLineStyle and MinorGridLineStyle
• Is IAxisViewModel.StyleKey the equivalent of IAxis.TitleStyle? (we just need to move our style definitions to XAML instead of creating Style objects in code)
• Is IAxisViewModel.VisibleRange equivalent to IAxis.DataRange?

Can there be equivalent IAxisViewModel.TickLabelStyleKey, similarly Minor/Major grid line StyleKey?

Background
Our view models hang around to hold logical state of charts. But they also hold some AxisCollection, bound to from SciChartSurface.

We get exceptions like: InvalidOperationException Element already has a logical parent, under SciChart methods in the call stack.
E.g. when reconnecting to a PC over remote desktop, where a chart was already loaded.

This change was also suggested as a solution to our other recent issue, here:
https://www.scichart.com/questions/wpf/axiscollection-isprimaryaxis-stops-auto-updating#sabai-entity-content-13950

The “Element already has a logical parent” exception doesn’t happen when clicking between multiple charts like that latter issue. I’ve prototyped a changeover (commenting out all the bits not directly equivalent) and it seems to resolve this exception.

registerVisibleRangeChangedCallback is not enough for me.
I want an active stop function like this.
surface.stopScroll()….

Hi,

There are some methods exposed in the API, ZoomBy and ZoomExtent which can programmatically be called from the code behind.
I am binding the series using IRenderableSeriesViewModel in MVVM pattern. Can we zoom the sciChart surface on a button click in ModelView?

Appreciating your help on this.

Thanks

Hello,
I’m trying to convert Android (Java) code to iOS (Swift), and I need to create a custom SCIZoomPanModifier. In the android code, onFling, onDown, and onDown were overridden, but I can’t seem to do that in iOS. How can I override onFling, onDown, and onUp in iOS to mimic the android code?

Thanks

VS2015 doesn’t support add-ins, so I can’t run the updater tool. Is there another option?

Hello. I’d like to point the Camera3D to a particular marker at x,y,z on my chart. I thought the ‘target’ property would do that, but changing it in the ‘Modify Camera Properties’ example doesn’t seem to change where the camera is pointing. What am I missing?

Thanks,
Daryl.

I add a LineAnnotation programmaticly to my surface and want to readjust it just like in the Examples Suite via clicking and draging the ends of the annotation.
As long as i dont use a Theme everything works fine. But when applying a custom theme the Manipulation points are not there anymore (and not only visualy, clicking at the end of the line also does not work. Furthermore the mousecursor does not change to a cross when hovering above the annotation end).

This is my Custom theme code:

Good day everybody!
I have got a problem. I need to place axis title above axis ticks. But I can’t find any method to do it. Could you help me?
Thank in advance.

Is there a simple white background theme?

Is there a way to update the entire data series instead of a particular y value at an index ?

Hi SciChart team,

I want to use SciChart (2D) in a new application. I have chosen .NET framework 4.0 as my target platform since that could still be installed on Windows XP according to Microsoft.
However at the SciChart WPF “System Requirements” (I suppose for the latest version, version 4), I see that it runs on .NET framework 4.0, but also requires at least Windows Vista. Does it really not run on XP? Could you elaborate that?

I see in an old question from “Lisbeth” 3 years ago, that you said it should be running on XP, provided that .NET 4.0 is available. Has that changed?

Regards,
Johannes
