If the paths sent to the output option are absolute paths, the module doesn't work properly.

Hi Basically if I say '/tmp/plot', I get a imagemagick error message about /tmp/fdfhjds3e73ff/plot.tmp./tmp/plot or something like that.

I see. The image format is unknown. Please try e.g. "/tmp/plot.png". Alberto Simões via RT <bug-Chart-Gnuplot@rt.cpan.org> 於 2019年2月25日週一下午5:33寫道： Show quoted text

Hi Will try (busy day). Meanwhile, it is curious that if I use just a name (like 'plot') it works. Will give details as soon as I am able to look into it.

Hi I've put the filenames ending in .png. Also, the code uses $chart->png; but the created files are not png (are postscripts) If I remove the .png, I get png files (although without extension) Thanks Alberto Simões ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Monday, 25 February 2019 18:48, Alberto Simões via RT <bug-Chart-Gnuplot@rt.cpan.org> wrote: Show quoted text

Hi, If the filename ended in .png, the module will convert the file to png automatically. However, putting "$chart->png" should just cause the program doing extra job. The resulting file should be kept png. Could you send me the program to diagnose? Alberto Simões via RT <bug-Chart-Gnuplot@rt.cpan.org> 於 2019年3月1日週五下午6:46寫道： Show quoted text

Ended up finding out that that is happening in case I use tilde expansion like this (see attach) On Sun Mar 03 20:43:34 2019, KWMAK wrote: Show quoted text
