var lineData = new XyDataSeries<DateTime, double>();
if I have a XyDataSeries<DateTime, double> then I can get the sweeping animation to work. If I change the XyDataSeries to XyDataSeries<DateTime, int> it fails to produce the chart and gives an exception stating
SciChartSurface didn’t render, because an exception was thrown:
Message: Specified cast is not valid.

Is this possible or does yaxis have to be a double? If I use fade animation it works properly. Thanks.

Hi John,
I’ve just investigated this, by making the following adjustment to our CandlestickChartExample (see this example here):
https://www.scichart.com/example/wpf-chart-example-candlestick-chart/
This is my modification:
private void CandlestickChartExampleView_OnLoaded(object sender, RoutedEventArgs e)
{
// Create a dataset of type x=DateTime, y=Double
var dataSeries = new OhlcDataSeries<DateTime, int>();
// Prices are in the format Time, Open, High, Low, Close (all IList)
var prices = DataManager.Instance.GetPriceData(Instrument.Indu.Value, TimeFrame.Daily);
// Append data to series. SciChart automatically redraws
dataSeries.Append(
prices.TimeData,
prices.OpenData.Select(x =>(int)x),
prices.HighData.Select(x => (int)x),
prices.LowData.Select(x => (int)x),
prices.CloseData.Select(x => (int)x));
sciChart.RenderableSeries[0].DataSeries = dataSeries;
// Zoom Extents - necessary as we have AutoRange=False
sciChart.ZoomExtents();
}
Making this change I don’t see any crashes for the Sweep Animation (I am working on v5.4.1, which is our latest nightly build of SciChart WPF v5.x).
I also added some more unit-test cases for Sweep Animation to test different data-types and don’t see any problems.
Can you make the above change and confirm if you see the same? How can we reproduce this crash?
Best regards,
Andrew
