Hello!

I want the chart to scroll from right to left and stop at left side. Don’t automatically scale, don’t move right.

I have a modifier:

ZoomPanModifier zoomModifier = new ZoomPanModifier() { ... };
zoomModifier.setReceiveHandledEvents(true);
zoomModifier.setXyDirection(XyDirection.XDirection);
zoomModifier.setClipModeX(ClipMode.ClipAtExtents);
// zoomModifier.setClipModeX(ClipMode.ClipAtMin);

When I scroll a chart left to the beginning, it scales the chart to one screen. So, all points are visible, proportions are broken.
When I replace “ClipMode.ClipAtExtents” to “ClipMode.ClipAtMin”, it sometimes stops at left side (as desired), but if I swipe too fast, it shows a right part of the chart and continues to scroll left.
Currently a first version of the SciChart library is installed.
As written in https://www.scichart.com/documentation/android/v1.x/SciChart.Charting~com.scichart.charting.ClipMode.html both “ClipAtExtents” and “ClipAtMin” have another behaviour.
My question is similar to https://www.scichart.com/questions/question/disable-scaling-on-zoompanmodifier, but for Android.

Answer, please, is it a bug? Has it been already fixed or expected to be fixed?

Hi Alex,

Unfortunately I’m not aware of such bug and I’ve just to tried ClipAtExtents mode in one of examples from our demo application and everything worked as expected :

  @Override
protected void initExample() {
    final IAxis xAxis = sciChartBuilder.newNumericAxis().withVisibleRange(1.1, 2.7).build();
    final IAxis yAxis = sciChartBuilder.newNumericAxis().withGrowBy(0.1d, 0.1d).build();

    final DoubleSeries fourierSeries = DataManager.getInstance().getFourierSeries(1.0, 0.1, 5000);
    final IXyDataSeries<Double, Double> dataSeries = sciChartBuilder.newXyDataSeries(Double.class, Double.class).build();
    dataSeries.append(fourierSeries.xValues, fourierSeries.yValues);

    final FastLineRenderableSeries rSeries = sciChartBuilder.newLineSeries().withDataSeries(dataSeries).withStrokeStyle(0xFF279B27).build();

    UpdateSuspender.using(surface, new Runnable() {
        @Override
        public void run() {
            Collections.addAll(surface.getXAxes(), xAxis);
            Collections.addAll(surface.getYAxes(), yAxis);
            Collections.addAll(surface.getRenderableSeries(), rSeries);
            Collections.addAll(surface.getChartModifiers(), sciChartBuilder.newModifierGroup()
                    .withZoomPanModifier().withClipModex(ClipMode.ClipAtExtents).withXyDirection(Direction2D.XDirection).build()
                    .build());
        }
    });
}

Do you use some other modifiers except ZoomPanModifier in your application? Maybe they interfere with each other in some way? If no, then can you provide a code which reproduces this issue?

Best regards,
Yura

    Thanks, Yura, for a fast answer. I will check this. Yes, I have some other modifiers: PinchZoomModifier, ZoomExtentsModifier. You are right, it’s better for me to understand whether they interfere with each other.
  • Alex N
    I removed other modifiers, but nothing changed. Probably will try to reproduce the issue in another project.
  • Alex N
    Yes, your code works as expected. A shake is experienced near left and right ends, but in whole it works.
