[MapServer-users] rotate pie chart / start at 12 o'clock

[Rahkonen Jukka]

Hi,

I do not really know, but I do not find such option from the documentation https://mapserver.org/output/dynamic_charting.html.
I can see something about starts and angles in the source code

https://github.com/MapServer/MapServer/blob/530f2bfdd99f27541ea9d08dc043d7e3c1e8f38c/src/mapchart.c#L257

So, now you have an answer, but I fear I could not make you much happier. BTW there may be more than 45 degrees between 3 o'clock and 12 o'clock, but it does not matter.

Aihe: [MapServer-users] rotate pie chart / start at 12 o'clock


Hello,

here again my so far unanswered question (I apologize for overlooking
the answer, if there was one):

is it possible to rotate a pie chart by -45 degree?
The first piece of cake should start at 12 o'clock, not at 3 o'clock

Jörg
