Re: Unusual Drawing Problem

Hi again,

I found the problem and it is a weird one. Apparently I chose to fill all but one of the histograms with the fill-style 3000, when I meant to use 1001 (solid). This however did not result in a compilation error or even a drawing error as the canvas was painted correctly and even saving in PNG format was fine. However, vector format pictures did not register the fill color. Now, when I added another histogram with a fill style 3354 to the "equation" caused all the histogram styles to be changed to 3001!

Anyway, this must sound too complicated. The bottom line is that I used 3000 as fill style instead of 1001 and the end result was this strange result! Problem solved.

Cheers,
Alexandros
