Please see the link image. Can we have multiple y axis and one x-axis on android Line charts.. any example link will be useful and ready to purchase if supports these type of charts in Android

We are working on line charts in Xamarin forms. We have a requirement to zoom in only one direction at one time. Once the user is done with zooming in one direction (say horizontal) and he reaches that place through scrolling, he should be able to zoom in another direction(vertical). Can you please assist this for the same

I am Using ECG Chart In Android. How To Make The ECG Moves Automatically in Horizontal.

Good morning,

I would like to ask you about the solution contained in the title. Is it possible to create realtime charts (for example 7-10) in a list (RecyclerView)? I have studied your example but there were none with a list.

The fragment in the example called createMultiPaneStockChartsFragment contains 4 charts. But unfortunately, it is not a list.
I made a simple activity with 5 charts in a RecyclerView, but charts are stucking a bit.
I do not call notify methods. There is only update LineData method:

oneChartClass.getLineData().append(oneChartClass.getLineData().getCount(), trendPoint.getValue());

Thanking you in advance…
Hubert

So I am trying to set paddings on the chart, so that the data series do not touch chart edges

I can’t do it with View’s method setPadding because then the black background is present (screenshot shows padding on all sides but I need just left and right)

Also, I managed to achieve no labels, axes, grids etc. but in totally hacky way; I set .withIsCenterAxis and then all other things to false

 .withAxisId(Y_AXIS_ID)
        .withDrawMajorBands(false)
        .withDrawMajorGridLines(false)
        .withDrawMinorGridLines(false)
        .withDrawLabels(false)
        .withIsCenterAxis(true)
        .withDrawMajorTicks(false)
        .withDrawMinorTicks(false)

Is there a normal way of doing this?

thanks

Hi Everybody,

I use a FastLineRenderableSeries with an XyDataSeries,

when I append data with a negative incrementation of X value,
nothing seems to be drawn

for example:

 Clear();
 for (int i = 0; i < 100; i++)
 {
      Append(100-i, i);
 }
 ZoomExtents();

but this example is working

 Clear();
 for (int i = 0; i < 100; i++)
 {
      Append(i, i);
 }
 ZoomExtents();

Is there a way to get this working? In my application data comes in real time, so I can’t sort them.

Thanks in advance for your help.

Hello everybody.

What is the best way to pass 3 y-values to single x-value?

Currently i’m using XyyDataSeries + XyDataSeries

Don’t know, if it’s best approach?

Hi all,

Why the API’s for iOS, Android and WPF are not identically?
I have seen many samples on the forum, but to adapt it to a different platform is very hard.
A lot of classes are different for each platform.

• Is there any “comparison” for the different platforms?
• Is this planned to unify the API’s?

Hello, for my bottom graph on my screenshot below, is it possible to dynamically change the black background to red? Indeed, when the microphone saturates like on the screenshot below I want to change the black background to red for 2 seconds, so I need to do it programmatically.

https://i.ibb.co/7XCLDwf/sature.png

I init my bottom graph like this :

 @Override
    public void initGraph(Context context) {
        Log.d(TAG, "initGraphs");
        SciChartSurface audioStreamSciChart = new SciChartSurface(context);
        mAudiostream.addView(audioStreamSciChart);
        xAxis = new NumericAxis(context);
        xAxis.setVisibleRange(new DoubleRange(startAudioStreamRange, endAudioStreamRange));
        xAxis.setDrawLabels(false);
        xAxis.setDrawMinorTicks(false);
        xAxis.setDrawMajorBands(false);
        xAxis.setDrawMinorGridLines(false);
        audioStreamSciChart.getXAxes().add(xAxis);

        NumericAxis yAxis = new NumericAxis(context);
        yAxis.setVisibleRange(new DoubleRange(-1.0, 1.0));
        yAxis.setDrawLabels(true);
        yAxis.setDrawMinorTicks(false);
        yAxis.setDrawMajorBands(false);
        yAxis.setDrawMinorGridLines(false);
        yAxis.setAxisAlignment(AxisAlignment.Left);

        audioStreamSciChart.getYAxes().add(yAxis);

        float lineThickness = SciChartExtensionsKt.dip(context, 1.0F);

        FastLineRenderableSeries f = new FastLineRenderableSeries();
        f.setDataSeries(scichartTools.getAudioDS());
        f.setStrokeStyle(new SolidPenStyle(ColorUtil.Grey, true, lineThickness, null));
        audioStreamSciChart.getRenderableSeries().add(f);
        scichartLayout = mAudiostream.getChildAt(0);
    }

I can keep a reference of my FastLineRenderableSeries to do it but i didn’t find any method to change his backgroud color.
Can i ?

Thanks,
Wavely

I have created a heatmap chart with values for the data series with four vertical lines of width 1. When the width of data series is smaller than width of SciChartSurface in pixels the four lines are clearly visible. However when I increase the width of data series to be bigger than the width in pixels, then some lines disappear, even though I’ve set the re-sampling mode to ResamplingMode.Max.

I wasn’t able to attach images to the post (got a Forbidden error), so I’ve uploaded them to Imagur:

I am working on CreateMultiPaneStockChartFragment example. Sometimes after I refresh data and call surface.zoomExtents(), the chart does not zoom to fit but stays the same. Why is this? I can then manually zoom to extents by double tapping the chart.

This is my (simplified) fragment code (stemming from the example but optimized for my case of regular updating) below. updateChart() is called periodically every 10 sec.

Hi, i want to make something like that : https://i.ibb.co/617TmD2/screenshot-line.png

I have tried HorizontalLineAnnotation but i successed to have it only on bottom graph : https://i.ibb.co/qsCjjGd/screen-bot-graph.png

Here how i initialize my top graph :

@Override
public void initGraph(Context context) {
    Log.d(TAG, "initGraphs");
    SciChartSurface spectogramSciChart = new SciChartSurface(context);
    spectogram.addView(spectogramSciChart);

    xAxis = new NumericAxis(context);
    xAxis.setAutoRange(AutoRange.Always);
    xAxis.setDrawMinorTicks(false);
    xAxis.setDrawMajorBands(false);
    xAxis.setDrawMinorGridLines(false);
    xAxis.setAxisAlignment(AxisAlignment.Left);
    xAxis.setFlipCoordinates(true);
    xAxis.setAxisTitle("Frequences (KHz)");
    xAxis.setAxisTitleOrientation(AxisTitleOrientation.VerticalFlipped);
    spectogramSciChart.getXAxes().add(xAxis);


    yAxis = new NumericAxis(context);
    yAxis.setVisibleRange(new DoubleRange(startSpectrogramRange, endSpectrogramRange));
    yAxis.setDrawLabels(false);
    yAxis.setDrawMinorTicks(false);
    yAxis.setDrawMajorBands(false);
    yAxis.setDrawMinorGridLines(false);
    yAxis.setAxisAlignment(AxisAlignment.Bottom);
    yAxis.setFlipCoordinates(true);
    yAxis.setAxisTitleOrientation(AxisTitleOrientation.Horizontal);
    spectogramSciChart.getYAxes().add(yAxis);

    FastUniformHeatmapRenderableSeries f = new FastUniformHeatmapRenderableSeries();
    scichartTools.getSpectrogramDS().setStartX(0f);
    scichartTools.getSpectrogramDS().setStepX(0.9f);
    f.setDataSeries(scichartTools.getSpectrogramDS());
    f.setMaximum(100);
    f.setMinimum(-30.0);
    f.setColorMap(new ColorMap(
            new int[]{ColorUtil.Transparent, ColorUtil.DarkBlue, ColorUtil.Purple, ColorUtil.Red, ColorUtil.Yellow, ColorUtil.White},
            new float[]{0f, 0.0001f, 0.25f, 0.50f, 0.75f, 1f}
    ));

    spectogramSciChart.getRenderableSeries().add(f);
    scichartTools.getSpectrogramValues().setSize(scichartTools.getFftSize() * scichartTools.getBatchSize() * 2);

    // I add the line but it's not displayed
    HorizontalLineAnnotation horizontalLine = new HorizontalLineAnnotation(context);
    horizontalLine.setHorizontalGravity(Gravity.FILL_HORIZONTAL);
    horizontalLine.setY1(5f);
    horizontalLine.setLabelValue("Label");
    spectogramSciChart.getAnnotations().add(horizontalLine);
}

You can see at the bottom of the function that i added it, but it doesn’t work on this graph. Why ? Maybe the graph is drawing over my line ?

Thanks,
Best regards

I would like to be able to have a Pie Chart go to the very edge of the layout it’s inside. Currently it appears as though there is some default built-in padding around Pie Charts that cannot be overridden. I’ve tried manually specifying padding and margins both programmatically (on the SciChartSurface object itself) and in the layout XML, but that default padding still exists.

I’ve included a screenshot of the sample app to show the padding I’m talking about (circled in red).

Hi,

In Android MVVM architecture, I am trying to @Inject ISuspendable through ViewModelModule, as I cannot pass this to my VMModel constructor.

@Module
abstract class ViewModelModule {

    @Singleton
    @Binds
    abstract fun getSuspendable(aSuspendable: ACMSuspendableImpl): ISuspendable

@Binds
    @IntoMap
    @ViewModelKey(MonitorViewModel::class)
    abstract fun bindsMonitorViewModell(monitorViewModel: MonitorViewModel): ViewModel
}


@Singleton
class ACMSuspendableImpl @Inject constructor() : ISuspendable {


    override fun decrementSuspend() {
    }

    override fun suspendUpdates(): IUpdateSuspender {
        TODO("not implemented")
    }

    override fun getIsSuspended(): Boolean {
        TODO("not implemented")
    }

    override fun resumeUpdates(p0: IUpdateSuspender?) {
    }
}

whereas my MonitorViewModel class as,

class MonitorViewModel @Inject constructor(context: Context) : BaseViewModel()  {

    @Inject
    lateinit var acmSuspend: ISuspendable


private fun loadMonitorData() {

        UpdateSuspender.using(acmSuspend) { //<! NULL ->
            iapDataSeries.append(Timestamp.valueOf(mData100Hz.getRtcTimeStamp().toString()), mData100Hz.emr.iap)
            uoColumnDataSeries.append(
                Timestamp.valueOf(mData100Hz.getRtcTimeStamp().toString()),
                mData100Hz.emr.totalVolume
            )
      }
}

How should I @Inject ISuspendable so that it should not be NULL. Please provide me some example snipped to work.
FYI,

I tried to follow the ECGViewModel but this sample used some custom solution and there is no use of DI.

Hi,

I have medical data displaying every 1s with Date as XAxis and ml/hr as YAxis. I want to control the display to let say, 6hr window in the current display by default whereas zoom-in can go to precisely 1hr and not below that and zoom-out reset to 6hr. How can I achieve this?

FYI, my data retention is for 72hrs.

BR,
Praween K.

Hello, I have added YAxisDragModifier and ZoomPanModifier to my surface and when I try to drag on Y axis I can move the X axis too and that is not the behavior that I was trying to get. I want when I drag/move YAxis not to move on the YAxis also.

Here is my code:

Surface.ChartModifiers.Add(new PinchZoomModifier());
Surface.ChartModifiers.Add(new ZoomExtentsModifier());
Surface.ChartModifiers.Add(new YAxisDragModifier { DragMode = AxisDragModifierBase.AxisDragMode.Pan });
Surface.ChartModifiers.Add(new XAxisDragModifier { DragMode = AxisDragModifierBase.AxisDragMode.Pan, ClipModeX = ClipMode.None });
Surface.ChartModifiers.Add(new ZoomPanModifier
{
Direction = Direction2D.XDirection,
ZoomExtentsY = false
});

Here is the video with the behavior:

Help please!

Hello everyone.

I have 2 stacked horizontally charts with

 .withMotionEventsGroup("ModifiersSharedEventsGroup").withReceiveHandledEvents(true)

so they drag and zoom in same way.

But when i put one finger on first chart, second finger on second chart – then total apocalypse happens.
Is it possible to zoom it, like two fingers on one chart or disable zoom in that situation, so charts will have no conflict?

(I think both chart just dragging in different directions in my case, but because they are linked – everything just shakes)

Edit:

Collections.addAll(mSciChartMainSurface.getChartModifiers(), sciChartBuilder.newModifierGroup()
                        .withPinchZoomModifier().withXyDirection(Direction2D.XDirection).withScaleFactor(SCALE_FACTOR_X_AXIS).build()

Hi, i am developping a spectogram, screenshot : https://i.ibb.co/7CPTZbg/screenshot-framed.png

I get the same result from your showcase, now there is some things i want to change but can’t resolve to know how to :
– How can i change data direction to spread from left to right ? (currently right to left)
– How can i clear FastUniformHeatmapRenderableSeries ? Method clear doesn’t work
– How can we set width of FastUniformHeatmapRenderableSeries’s layout to be fixed to a specific seconds number ? (example : there is 10 seconds of data between left and right)

Thank you,

I am developing an application which can receive the data from an ECG circuit, then transmit that data through Bluetooth into my phone application. My phone application would then display the ECG graph. I tried downloading the ECG demo example and it works find on its own. I am trying to incorporate that into my own project and see if it works. However I have been getting errors. Please help me out! Thank you!

Hi,

I am currently using SciChartDebugLogger to enable logging but I am not sure what information the vararg provides

     public void logInfo(String tag, String stringFormat, Object... args) {  }

what does the arg object provide? can it be converted to a readable string format? what does the string format mean?

I have many users who have been sending crash reports with this stack trace and I can’t figure out what part of our code would be triggering this since the stack trace doesn’t mention any classes that are we’ve coded. Any idea what could be triggering this based on the stack trace?
