Re: gnuplot: set terminal png

[Vic Norton]

Thanks for all the replies to my original question:
   How do you get "gnuplot> set terminal png" to work?
I was really interested in just this question, not in various ways to
convert graphical output into pngs.

As I mentioned I am using Mac OS X 10.3. I have reinstalled gnuplot
and the "set terminal png" command works fine now. I'll put down what
I did here for other Mac users. Maybe it will help someone.

You can get gnuplot 4.0.0 from sourceforge.net. Two alternatives are
   http://prdownloads.sourceforge.net/gnuplot/Gnuplot-4.0.0.dmg
   http://prdownloads.sourceforge.net/gnuplot/gnuplot-4.0.0.tar.gz

As a Mac person I was inclined toward the first alternative. This is a
binary package that installs itself. This is how I installed gnuplot
4.0.0 the first time, what I was using when I asked my original
question. Unfortunately there is no way that "set terminal png" will
ever work if you take this alternative.

OK, so the second alternative is necessary. Here is how I did the
installation, including the installation of certain prerequisites.
Each installation part shows the source of the package followed
by the requisite commands. The first command always changes to the
unpacked package directory.

Vic
