Dear all,
I am experiencing some minor issues when trying to plot things.
Actually, I am not sure whether these are problems related to gnuplot or
to gretl.
First, I really like the new "--font=fontspec" option; thanks again for
implementing this. I wrote a small function for plotting vectors which
allows the user to set a bunch of different options. You can find the
function at the bottom
I ran the following 5 scenarios of which only scenario 1 works as intended.
First there seems to be a problem with the ""literal set mono" option
which rules out controlling the line width under both the "display" and
"pdf" output.
Second, when the output format is pdf, I also can't control the font
size; irrespective of the dashed and monochrome options.
Thanks for help and Happy Easter!
Artur
