Thanks for your posting and considering Aspose.Cells.
As you know Aspose.Cells supports most of the charts and you can take your worksheet and chart images. Also you can save your individual chart into pdf. Reading your posts, we feel your requirements can be fulfilled by Aspose.Cells.
For chart issues, we do support complex charts. You can try creating complex charts manually using Microsoft Excel and then save your excel file into pdf. There you will get the png image of your chart and then check if it is ok or not.
For any problem, you can report to us in this forum, we try to fix user issues mostly in 4 working days but sometimes, we take couple of weeks too if the issues are complex.
SVG images of worksheet and charts are also supported. Mostly SVG issues are reported less because this image format is not used by most of the users. So if you find SVG issues, then please report to us, we are able to fix such issues in due time.
Aspose.Cells is a reliable solution for you. If some issue is broken in newer releases, we take it very seriously and log it as a regression issues and report it to our higher management. So our effort is always to give solid fixes that do not break the existing functionality. Besides, you can always ask us to implement some new feature. We will analyze your request and implement it in future releases if possible.
