I am trying to draw some MARKER_POINTs (with DRAWING_MARKER tool) of varying sizes based on some input data. I was wondering if it is possible to support the transparency level for the DRAWING_MARKER (MarkerType = MARKER_POINT). I tried to use the DRAWING_ELLIPSEHIGHLIGHT in place of a MARKER_POINT. I can set the transparency level for the ellipse to my liking. However, I run into other issues with what I am trying to do: 1) I would need to specify two coordinates instead of one for the ellipse. This is manageable with some additional calculations to offset both coordinates from the center. 2) I can change the height of the ellipse in a pretty granular fashion but the width can only be varied in multiples of sc.ChartBarSpacing, I believe. This results in a lot of calculation overhead to figure out the appropriate height and width for the ellipse if I want to keep the area of the ellipse consistent with the input data I am trying to graph. The MARKER_POINT works great because the radius can be changed in a very granular fashion. Thanks.
