    Hello Nicu,

    Thank you for your interest in Chart for Android.

    I'm not sure what exactly you mean by getting coordinates for a point with coordinates x and y. You have also posted a support ticket where you reference conversation about getting the coordinates in terms of pixels for a data point in terms of point in a series. If you need to get the coordinates where a data point (for example a bar in a BarSeries) is drawn, then here's how:


    That is, you get the series that you're interested in (the first series in the example), you take its model which contains the data points that are drawn, you take the point whose coordinates you seek (the second point in this example) and then you take its center which is a point the coordinates of the center of the point.

    If this is not what you are looking for, please explain in more details you scenario and what coordinates you would expect.
