Thanks, I got it and will investigate what can be done. Issues with the labels seems to mostly because Excel basically saves 2 versions of the chart inside the xls file (one for Excel 2007 and the other so 2003 can read it), and the Excel 2003 version /the one we read) seems to be wrong. (As you can see by opening this file in Excel 2003).
About the colors, it seem related to the fact that those are not real colors but 3d gradients, and while we read the color information from the Excel2007 part of the file, I am not sure we read gradients from there. I will investigate.

Adrian.
