[Gnuplot-info] Problem: missing dots when converting to pdf

[Alejandro L. <all...@ya...>]

Hello,

Eventually I have a problem with my plots, when I use the option "with 
dots". First, I save my plot as a postscript:

set terminal postscript
set output 'plot.eps'
plot 'mydata' u 1:4 w d
set output

Then, I use this last figure for generating documents (I use the command ps2pdf 
to obtain the final pdf file). The problem that I observed (eventually) is that 
when someone else opens the obtained pdf file in windows, those figures are 
empty (i.e., dots do not show up). Those figures look great to me, but I would 
like to be sure that everybody can see them also. Currently, I have Ubuntu 9.04 
in my computer but I used other distributions. 

Can you tell what is my problem? Am I going anything wrong?
Thank you very much for your help.
