Transparency of a specified colour is not a property of a Bitmap which is what a chart returns from its Draw method. Transparency of a specified colour is obtained by using a Drawer from ImageLib or a Drawer Ex from ImageLibEx. Drawing the Bitmap returned by a charts' Draw method on another Bitmap using DrawImage with the transparent parameter set True will render the colour specified by SetTransparentColor transparent where it appears in the chart.
