Has anyone ever encountered this problem?
Could you give me a help? How to solve this problem?
The app didn’t run in the method of ‘getStrokeColors()’, when I debugged.
public class BubbleChartFragment extends ExampleBaseFragment {
...
{
...
FastBubbleRenderableSeries mRSeries = sciChartBuilder.newBubbleSeries()
.withDataSeries(dataSeries)
.withZScaleFactor(zScaleFactor / 10f)
.withBubbleBrushStyle(new SolidBrushStyle(0xffff0000))
.withAutoZRange(false)
.withStrokeStyle(0xff00ff00, 20f)
.withPaletteProvider(new StrokePaletteProvider())
.build();
}
private class StrokePaletteProvider extends PaletteProviderBase<FastBubbleRenderableSeries> implements IStrokePaletteProvider {
private final IntegerValues colors = new IntegerValues();
private final int[] desiredColors = new int[]{0xFF00FF00, 0xFF0000FF};
protected StrokePaletteProvider() {
super(FastBubbleRenderableSeries.class);
}
@Override
public void update() {
final BubbleRenderPassData currentRenderPassData = (BubbleRenderPassData) renderableSeries.getCurrentRenderPassData();
final int size = currentRenderPassData.pointsCount();
colors.setSize(size);
final int[] colorsArray = colors.getItemsArray();
final int[] indices = currentRenderPassData.indices.getItemsArray();
for (int i = 0; i < size; i++) {
final int index = indices[i];
colorsArray[i] = desiredColors[index % 2];
}
}
@Override
public IntegerValues getStrokeColors() {
return colors;
}
}
}

Hi,
If I create a bubble chart with auto x-range and keep appending bubbles (so the xrange grows over time to show all the data), after a while some of the bubbles will start to flash on and off. Its as though if they are centred between pixels then the whole bubble doesn’t get drawn.
Any ideas?
Cheers
Felix
