Hi,
Plaese find the below sample which demonstrate the issue mentioned -
1. I have set a rotation of 45 for category axis tick labels. When I take image using toImage, it overlaps with plot area. Plaese find the screen shot for details.
I am using Aspose.CellsV2.1.2.4. BTW, do you have any utility class/method to find aspose version? Now I have a bunch of Aspose.Cells jar files. It was nice if I can get the version with a single line of code in my java file.
