TPieSeries.ExplodeBiggest = High CPU

Post by Fab2022 » Tue May 03, 2022 3:17 pm

Hello,

Tested on Teechart Pro v2021.32.210430 32 bits with Delphi 10.3

There is an old bug (reproduced in old version) when in a TPieSeries, which contain a certain number of records, if you set ExplodeBiggest for example :
ExplodeBiggest = 20
=> This take a lot of CPU to display/redraw Teechart

Easy to reproduce full sample in attachment.

Hello,

Sorry for the delayed reply here.
The problem seems to be on the shadow drawing.
Could you please confirm if hiding it solves the problem for you?

Code: Select all

Series1.Shadow.Visible:=False;
