Re: [Gnuplot-info] [BULK] Re: png plot error.

Thanks Hans,

Actually you are right it is ;

[hrmoper@cluster ~]$ gnuplot --version
gnuplot 4.0 patchlevel 0

I also noticed from the help menu that I need libgd to create png images. I tried installation of libgd, but I still get the same errors.

PNG images are created using libgd, with optional support for TrueType
 and Adobe Type 1 fonts via libfreetype. Version 1.8 or greater of libgd
 is required.

I however have a small conversion script, from postscript to png, which works perfectly. For the time bieng I will create my images in postscript and convert to png. But I would have liked to create the images directly to png.

Thanks.

No such version.  The actual version numbers look like this:

	Version 4.0, patchlevel 0

Your gnuplot executable doesn't have the right set of terminals for the 
tool you're using to drive gnuplot.  You'll need to adapt your external 
tool or rebuild a current gnuplot with the required terminal drivers.
