Graphics, Figures & Tables ⇒ Darker colors in PDF output

[gregsa]

I am using a gnuplot (cairopdf terminal) to generate colorful charts. Then I include those pdf files with \includegraphics{}. All is complied using pdflatex.

In the final pdf file most of the pictures have darker colors then in original pdf files. I could live with that but this does not happen in all cases. Some remain not changed.

Have any of you encountered this problem before?

Any help wolud be appreciated.

I used to use gnuplot before I started using PStricks. I understand what you are working with. Even with the PDF looking light the figures generally print nicely, here is a link that I found that may help. It has been over a year since using Gnuplot, but maybe this will help.

I think you are looking for "thickness" for your graphs, so the lines show up better, and your axes, etc.

I would strongly recommend switching to PSTricks it is much easier and produces much higher quality graphs that Gnuplot ever could.

I hope this helps.

If you have a graph, send me the code and I will show you how nice PSTricks looks.

Best,

Nicholas

There is the pgfplots package (based on pgf/tikZ) which allows also to create charts and the like. It uses Gnuplot as backend.

I suggest to attach a file produced by Gnuplot along with the according dataset so we can reproduce it with other tools. Additionally you can present the corresponding Gnuplot script. But it's important to have the dataset here.
