Hi Mathias,
Thanks for your interest in Syncfusion products.
It is possible to set two different colors to the CandleSeries depending on the Open and close price, by handling the PrepareStyle event of that series.
Example:series1.PrepareStyle += new ChartPrepareStyleInfoHandler(series1_PrepareStyle);
// Customize Candle series Style
void series1_PrepareStyle(object sender, ChartPrepareStyleInfoEventArgs args)
{
ChartSeries candleSeries = sender as ChartSeries;
if (candleSeries.Points[args.Index].YValues[2] > candleSeries.Points[args.Index].YValues[3])
{
args.Style.Interior = new BrushInfo(Color.SteelBlue);
}
else
{
args.Style.Interior = new BrushInfo(Color.Brown);
}
I have attached a sample that illustrates the same in this link below.
