I have only gd.so library after installing "php5-gd" package. This module is included in apache config.
In phpinfo() function i see:
GD Support enabled
GD Version 2.0 or higher
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.3.7
T1Lib Support enabled
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support en
The only other thing I can think of that would prevent it from even attempting to create the graph is a missing or inaccessible resource/graphimg.png file.
Yes. No graphimg.* files were there.
But without php5-gd package (Debian/Ubuntu) with this files it also didn't work.
Now it's work perfectly.
Thank you for help!
