Waterfall chart issue

We don't have support for waterfall chart in PPTX to PDF conversion in .NET Standard. We have added the details under notes section in supported chart types page. Also, we don't have any plans to implement this feature.

Mohamed, as promised earlier, we have included the fix for the reported issue with “Stock chart is renderer improperly while category axis type is date time in Presentation to PDF conversion” in our latest weekly NuGet release (v25.2.6).

Root cause of the issue:
According to the behavior of Microsoft Presentation, blank cells are included in the data range for the stock chart, and the category axis type is set as date time. However, empty points are not considered in this process. OfficeChart doesn't currently handle this behavior, which causes the stock chart to render improperly during PDF conversion.
