Aspose.Cells 21.12, java.lang.NullPointerException in Chart::toPdf method


I got a java.lang.NullPointerException exception when I called Chart::toPdf method. It seems like there is a problem when there is a dataset pointing to hidden rows.

I have attached an example and a program to reproduce it. (37.8 KB)
