So basically I want to have a candle series with different colours at different parts of the x-axis .. I couldn't find any easy way to do this, so tried just adding three separate series to start with. Unfortunately there is a bug where if there is more than one series the bars are not drawn properly and really thin, but that aside, I tried to adapt another solution I found on here by using a custom class
public class CustomCandleSeries1 : CandleSeries
{
//Returns the Candle Segments
public ObservableCollection<ChartSegment> CustomSegment
{
get
{
return this.Segments;
}
}
}
I can now access the Segments and change colour like this;
void ColorSegment( ChartSegment segment)
{
var canvas = segment.GetRenderedVisual() as Canvas;
if (canvas is null) return; // before ready
(canvas.Children[0] as Rectangle).Fill =
etc.
}
The problem i have is when to do this. The example I followed handled the Chart Loaded and Size Changed events but that was for doing something different and although it works ok, it doesnt handle new data being added to the Series Data
I have tried accessing the Collection Changed Event for the Segments Collection in the Chart Series to catch new items added and call my function at that point - this doesnt work though as at the point the Event is fired the Candle is not rendered, so segment.GetRenderedVisual() is null.
So my question is, is there any way of injecting my function when a new Candle is created and rendered?
Hope that makes sense and thanks for any help.
