New bar-of-pie and pie-of-pie chart types added to 24.8 for bug 50934 are not yet listed in the relevant help page: https://help.libreoffice.org/24.8/en-US/text/schart/01/type_pie.html
That does look like it needs updating. Changing to "New".
I'd suggest the following descriptions: === Bar of pie - this subtype shows a pie chart on the left, with the last three entries in the data column aggregated as a "composite" sector. The composite sector is broken down in a bar chart on the right. Pie of pie - this subtype is similar to Bar of pie, but the composite sector is displayed on the right as another pie chart. === Note that "three entries" is the current behaviour, but will change with the solution to bug 161090. https://bugs.documentfoundation.org/show_bug.cgi?id=161090

I've incorporated that language into a patch. I'll keep an eye on bug 161090.
Dione Maddern committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/help/commit/d2649657002eeabbf686333faccd2b141d3bc9dc tdf#161091 Document new bar-of-pie and pie-of-pie chart types
I'm going to mark this as "resolved". We can revisit the help page when the feature is updated.
