chartScale Width Height dpi settings

[habibalex]

float chartScaleWidth = (float)ChartingExtensions.ConvertToHorizontalPixel s(chartScale.Width, ChartControl.PresentationSource);
float chartScaleHeight = (float)ChartingExtensions.ConvertToVerticalPixels( chartScale.Height, ChartControl.PresentationSource);

I recently noticed my chart indicators draw incorrectly in OnRender. I needed to convert the chartScale width / height using these helper functions. Is this by design or a bug?

Hello habibalex,

This is expected with how changing the DPI modifies the rendering coordinates, and is documented in the help guide.
