Questions

I have stock charts and want to prevent the user to go beyond the Min/Max datetimes (left, right). I tried applying setVisibleRangeLimitMode() to XAxis but it has no effect:

private final DoubleRange sharedXRange = new DoubleRange();

//sharedXRange.setMinMax(0d, response.body().getData().size()-1d); // not helping
...
final CategoryDateAxis xAxis = sciChartBuilder.newCategoryDateAxis()
        .withVisibility(isMainPane ? View.VISIBLE : View.GONE)
        .withVisibleRange(sharedXRange)
        .withGrowBy(0.1d, 0.1d)
        .build();

xAxis.setMinimalZoomConstrain(10d); // minimum 10 points
xAxis.setVisibleRangeLimitMode(RangeClipMode.MinMax); // not working
//xAxis.setVisibleRangeLimit(new DoubleRange(-5d,5d));
...

I am thinking that maybe I should set Min and Max to sharedXRange, but couldn’t find in the docs what value to put into (tried with index, and Date without luck).

This issue repros on Android 4.4 API 19, but not API 27. It happens with the example project (Multi-Pane Stock Charts). The issue is that on certain zoom levels, the x-axis labels are cut off (so instead of displaying 11 Mar, it just displays 11).

I have tried to override TradeChartAxisLabelFormatter with my custom implementation but saw the same issue, so the bug seems to be in the provider or somewhere else.

I’m using a CategoryDateAxis and seeing the following crash many times in production. The issue is that SciChart is not synchronizing access to SimpleDateFormat, and this will lead to a crash.

Please see following thread for more details on how to fix this issue:

                            .withGrowBy(0.0, 0.05)
                            .withAxisAlignment(AxisAlignment.Bottom)

UpdateSuspender.using(surface) {
                Collections.addAll(surface.xAxes, xAxis)

data object has about 300 valid data points.

Any ideas what’s going on? I tried running this on a new activity. If I swap LogarithmicNumericAxis for a NumericAxis, everything works fine. I looked at the decompiled .class file where the crash was occurring (I don’t have the source for SciChart), and it seems like the crash occurs when major ticks fail to get generated (majorTicks.size == 0). I tried disabling all minor/major ticks but no joy.

for(int var22 = majorTicks.size(); var22 >= 0; --var22) {
            double var23 = var4.fromExponent(var11);
            double var25 = var22 < majorTicks.size() ? majorTicks.get(var22) : majorTicks.get(var22 - 1) * var23;
