Weird. I am unable to create a png file using Chart::Gnuplot. All necessary is installed (ImageMagick) for the convert utility. The output is set to file.png. I have also tried $chart->convert('png') and $chart->('png'). The output file is always "PostScript document text conforming at level 2.0". I have also tried jpg and gif but always get the some output type. If I manually use the convert utility all works fine. Any ideas. Using Chart::Gnuplot 0.16.
