Hi John,

Thanks a lot for providing such a thorough explanation of how this can be done. I really appreciate your putting in time to answer these queries. I will download 2.4 and check it out. Basically, I wanted to do this because I wanted to highlight an area of an already drawn chart. In the meantime, while I could not know how to do this, I had checked out orkut's photo-tagging feature which allows us to draw a rectangle over an already existing image. While I implemented drawing a rectangle over an image using GWT with client cordinates, I realized that it fails when my image is larger than my browser window. Because as I scroll down or on the side my client cordinates with respect to a reference point at the top are lost. As in, my image's top left edge whose cordinate was say (20, 100) before I scroll is no longer in the frame and (20, 100) becomes the cordinate of the point at the top left of the browser window which is not the top left edge but a portion of the image which came into picture when I scrolled down. I saw that you are using clientX and clientY. So I thought maybe this information would be useful. I don't know if I could communicate my thoughts clearly. But I will check out your code and I have put in an enhancement request on the GChart issue tracker. regards, Saurabh Hirani.
