Hi jeremy,

It seems to work fine here using the example at All Features\Welcome !\Chart styles\Statistical\Box-Plot in the features demo and adding a page number tool on it. You'll find the features demo at TeeChart's program group.

Could you please send us an example we can run "as-is" to reproduce the problem here and let us know which TeeChart version are you using?

You can post your files at news://www.steema.net/steema.public.attachments newsgroup.

Hi jeremy,

Thanks for the project. We could reproduce the issue here. Paging doesn't work fine for BoxPlot series. I've added this issue (TF02011632) to our defect list to be fixed for future releases.

Hi.

I think the problem is box plot series was not designed for paging. You cannot simply split data points between different boxes (series) using paging. For each data group you have to create a separate box series and then populate it with data (or define median, etc... values). Then you can (but not with the pagenumber tool) "zoom" on group subset by using axis SetMinMax method.

In short, if you want to limit number of boxes (series) per page, then the best way is to use tChart OnPage* events and limit axis scale by using axis SetMinMax method. PageNumber tool cannot handle this specific case.

We'll review how boxes can be handled when MaxPointsPerPage>0 for next major release.
