i had to change my $graph->SetFileFormat("gif"); to png ($graph->SetFileFormat("png")

because i am running gd 1.8.3. but somehow all the images turn out to be fully black (nothing else)
another question i saw someone running a gd version highter than 1.6.2 with GIF support ? i thought they removed GIF support since version 1.6 due to legal problems ... ?
any help here is appreciated
thanks in advance
[edit]:
my gd specs.
