When trying to create a candlestick graph, if I have data with no high low bars with a range of more than 0.00950 then the graph won’t zoom in on initial load. See my code further below. Above 0.00950 and it’s okay. BTW I’ve tried withVisibleRage.

Please help, my trial is going to run out soon. I’m really stuck.

For example:

The following won’t zoom in:

[
    {
        "symbol": "AUDCAD",
        "ctm": "2018-02-10 09:00:00",
        "high": 0.98000,
        "low": 0.97100,
        "open": 0.97900,
        "close": 0.97800,
        "volume": 1238
    } ]

The following does zoom in:

[
    {
        "symbol": "AUDCAD",
        "ctm": "2018-02-10 09:00:00",
        "high": 0.98000,
        "low": 0.97000,
        "open": 0.97900,
        "close": 0.97800,
        "volume": 1238
    }
]

Here’s a screenshots:

Here’s the code which produces the charts:

final CategoryDateAxis xAxis = sciChartBuilder.newCategoryDateAxis()
        .withVisibility(isMainPane ? View.VISIBLE : View.GONE)
        .withAutoTicks(true)
        .withGrowBy(new DoubleRange(0d, 0.1d))
        .build();

final NumericAxis yAxis = sciChartBuilder
        .newNumericAxis()
        .withAxisId(PRICES)
        .withAutoRangeMode(AutoRange.Always)
        .withDrawMinorGridLines(true)
        .withDrawMajorGridLines(true)
        .withMinorsPerMajor(10)
        .withMaxAutoTicks(20)
        .withGrowBy(new DoubleRange(0d, 0.1d))
        .build();

surface.getXAxes().add(xAxis);
surface.getYAxes().add(yAxis);

surface.getRenderableSeries().addAll(model.renderableSeries);

Is there an convenient way to convert an existing IXyDataSeries<Date, Double> to IOhlcDataSeries<Date, Double> ?
How do Scichart collapse Candlesticks (and presumably merging with neighbouring candlesticks) when its very zoomed out e.g. 1 year period
