Questions

I want to show my values between (-10,60) but the y axis is adjusting automatically according to data .

I am trying to make a custom Label Provider by extending NumericLabelProvider as it is described here:
https://www.scichart.com/documentation/android/current/webframe.html#Axis%20Labels%20-%20LabelProvider%20API.html

private class PercentLabelProvider : NumericLabelProvider
{
    public override string FormatLabel(Java.Lang.IComparable dataValue)
    {
        return string.Format("{0:P0}", dataValue);
    }
}

However, this is not possible, because FormatLabel can not be overridden.
This is the error message:
“cannot override inherited member ‘FormatterLabelProviderBase.FormatLabel(IComparable)’ because it is not marked virtual, abstract, or override”

DateLabelProvider has the same problem.

I need need to use both.

Is there a solution for this issue?

On Android, the docs say that AnnotationSurfaceEnum should have the “BelowChart” enum case, but it is actually missing in the code. It is there on iOS but not on Android.

I need this particular enum case, because otherwise the annotation boxes are hiding the data series and the grid lines.

What should I do?

Hi, I want to draw a chart like the attached image.

This is a chart with XyDataSeries, it show as vertical line at each data point and verticle line is a dotted line in order to separated from other series.
Since the OHLC chart will have the open, close on the data point and an impulse chart is forced to draw from an axis, is there any better way that can achieve a series like this? Thank you!

Hi,

I’m using RubberBandXyZoomModifier for zooming and i want to reverse the process.
If i double tap to screen, i want the process to be reversed and back to last zooming level.
Firstly how can I dedect the double tap, and secondly how can I reverse the process?

Tnx.

I set a rolloverModifier to a CandlestickSeries, but I can not find a API to hide RolloverMarker,I only find a article about WPF(https://www.scichart.com/documentation/v5.x/webframe.html#RolloverModifier.html)， how could I hide RolloverMarker or change the style of RolloverMarker in Android?

Hello
I want a realtime chart that start rendering from middle of the screen, not from start of the screen

Hello
I want to make a real time chart that its visible range consists of two part.
The first half of the visible range of chart is always blue and the rest is black.

Hello,
I want to use SubDayTextFormatting in android so that when the visible range reaches the same day, e.g. as I zoom, it switches from dd:MMM:yyyy to HH:mm.
How can I do that?

Hello

I was wondering if it would be possible to create a simple clean looking chart like described in the attached image. I am looking for a “SuccessRateChart” that has some similarity to the PieChart but does not use the whole circle to describe its content. I would also need a way to adjust the visible radius of the Pie. In means of information visualization you often hear the term “doughnut chart”…

On way could be to draw some circle stacked over the chart itself, but there should be a better solution.

Would love to hear from you,

Kind regards,
Stephan

How to use ClipModeX on our desired values instead of ClipAtExtents or ClipAtMin/Max?

Hi,
We want to use scichart for ios-android and wpf platforms to use in our applications developed by our company for Financial (Trading) purposes. In our review, we found that we can use Linear Trendline for wpf platform in your documents. However, there was no documentation for the android and ios platforms. Since Linear Trendline is of great importance for trading, it is important to know whether this feature is available or if it will be developed as a new feature by you. I would ask you to provide information on the subject.

I want to maintain shape of scichart minor and major grids as square as shown in image below how can I do that?

Hello,

Let me first describe the issue we have and why I think a possible solution would be to catch the double tap event.

Our chart consists of 6 series. We have an X axis that shows timestamps and 5 Y axis’ for different data like pressure value, temperature, etc. which are of type double. Additionally under the chart we have a legend that displays these 5 Y axis series (one series per one Y axis) with ability to change the visibility of the series and axis.

The problem occurred when as an example, temperature values throughout are constant, e.g. 24.5. The line gets drawn and it is a stable line. Axis is also displayed. However, when a user does the double tap gesture on the chart surface, which usually resets the zoom extents, the axis that has static/non-changing values does some sort of re-initialize animation and after several of double tab gestures only axis label remains (minor and major ticks disappear).

If I could catch the double tap gesture event and override it I could for example say that if the data is static don’t do anything. However, I don’t know where this event is and how to override it.

Any help would be much appreciated.

Thank you.
Regards,
Paul.

Hello,

I have an app using scichart 2.1 that runs well. I am trying to migrate to use androidx libraries and am now encountering a crash when runnign setRuntimeLicenseKey(), as shown by the trace below. Any idea how to go about resolving this? Is this something that would be solved by upgrading my SciChart version?

I have minSdkVersion 23, targetSdkVersion 28

Thanks

Hi,
I am using Scichart android ,for Linking Chart Modifiers of Multiple charts I use these lines of code as shown below but it will not synchronize charts on X axis properley sometimes what is the reason ?
Is there is any other method to do that?

ModifierGroup chartModifiers2 = sciChartBuilder.newModifierGroup()
// Setting MotionEventsGroup
.withMotionEventsGroup(“SharedMotionEvents”).withReceiveHandledEvents(true)
.withLegendModifier().withShowCheckBoxes(true).withReceiveHandledEvents(true).build()
.withZoomPanModifier().withClipModeX(ClipMode.ClipAtExtents).withReceiveHandledEvents(true).build()
.withPinchZoomModifier().withReceiveHandledEvents(true).build()
.withZoomExtentsModifier().withReceiveHandledEvents(true).build()
.withRolloverModifier().withReceiveHandledEvents(true).build()
.build();

Hi,
I am using Sci Chart android I want to Share/Link Custom Modifier on Multiple Charts ,
How Can i do that?

Is dashed line is available in Scichart Android?

Hello.

I am working on Xamarin Android project with C#. Since having a legend within the chart causes problems with too many axis’ (no scrolling is available thus selecting different series in a legend becomes unavailable) and having a legend outside of chart area, anywhere we desire, would be of a preference, is there a tutorial on how could I achieve such a thing? Our project needs this functionality for both Android and iOS.

Would be grateful if anyone could help out with this issue.

Thank you in advance!

Hi…..
I could be able to set clip mode for X axis in ZoomPanModifier(), In the same way I would like to set clip mode Y axis but I couldn’t.
Is there is a way to do that?

I am still experiencing the effects of this defect despite using v2.5.0.2598 of the Android libraries. Can someone please explain to me how to circumvent this behavior? It seems silly to require a base series that is ultimately going to be replaced by real-time updates.

Cheers

When I import my own .jar library after importing Scichart .aar libraries(core and data) my own .jar library generates an error(Error: findLibrary returned null). How can I overcome that error.

Hi,
I am working on Scichart android appliication.By default it is appending infinite Yvalues which are randomly generated one by one. I want to append finite data in AnimatingLineChartFragment() but it will not accept it, like when I append arrayList of yValue it will generate an error and ask to add Collections.singleton(t) on 1st argument .Afterwards when I run the programme it works fine but when Fifo Capacity ends it starts to draw last line again and again. Plz help me that how can Animate Lines on my data?

I am developing an Android application for ELD. I have also explored the graph options SciChart is offering but I could not see a very similar graph to the image I have attached.
Please help me in choosing an appropriate type graph. It would be more helpful if you could name type of the graph I have attached.

Hi!

I’ve put a couple of charts in a recyclerview based on this example. I’m using a custome theme that’s basically just a white background and grey gridlines. When the charts get recycled (after scrolling them out of view and then back) they start to look weird. Does anyone know what is causing this behavior? I’ve tried two different versions of SciChart, screenshots attached below. Additionally I used to only get some random black squares like this in version 2.0.0.1654, but I can’t seem to reproduce that now.

Chart normally:

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);

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.

Hi,
so I want ask about the gradient color does the latest version of scichart support using gradient color in charts for both xamrin.android and Xamarin.ios

Does Sci chart has any framework to support UI Automation in Android/iOS? Also I came across some screenshot based test for verification, Is this available for licensed user to test in Android/iOS?

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.

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?

When I yAxis.setVisibleRange(0.d,10.d) then add a series, it triggers AutoRange to resize the graph.

If the VisibleRange is ANYTHING other than 0,10 (even 0,10.001) then it doesn’t resize the graph.

during my search, I found that setting Axis.AutoRange to .NEVER will stop the issue from happening.

I still wanted to post this here because this is a notable bug that others will come across, and I wanted to show what solution I found.

How to set the background, font color and font size of the text label on the map；

Source as this：

PenStyle penStyle = new SolidPenStyle(getColor(R.color.baselineColor), false, 1, new float[]{7, 3, 3});
for (int i = 0; i < baseValues.size(); i++) {
baseLines.add(sciChartBuilder.newHorizontalLineAnnotation()
.withY1(baseValues.get(i))
.withStroke(penStyle)
.withAnnotationLabel()
.withHorizontalGravity(Gravity.FILL_HORIZONTAL)
.build());
}
