Location in pixels of point values

[joe.awwad]

Hi, I'm trying to locate the position in pixels of the points in my charts. I'm doing the following:

int yp = chart.getAxisY().valueToPixel(chart.getData().getY().get(series, point()));

int xp = chart.getAxisX().valueToPixel(point);

The above code is working well except for pies and doughnuts. It's returning [xp = 0, yp =0]

Is there any way of getting the location of a pixel inside the area covered by value in a chart?

I would appreciate any help on the matter.
