Bug in Logarithimic axis

Post by johnnix » Tue Nov 15, 2022 7:00 am

Hello,

I just upgraded to the latest version and there is a bug in logaritmic axis max position (appears to be placed in the middle of the axis). I really need a quick fix for this!!!

Hello,

I thing the issue can be found in line 5980 of TeEngine.pas, the following works ok

Code: Select all

if FInverted then result:=Round((ILogMax-ln(Value))*(IAxisLogSizeRange))
                     else result:=Round((ln(Value)-ILogMin)*(IAxisLogSizeRange));
Can you pleae confirm this ok to keep?

Hello,

Simply drop a TChart component and set Y axis to be logarithmic, minimum 1 and maximum 1000
