How to "export" a graph to png or something insertable in Word ? I know there are a dozen tutorials for this on the 'net, but I'm having trouble just finding a simple example.
Follow these;
Once you are happy with your plot, set your output terminal type to ``Postscript.''
gnuplot> set terminal postscript
Graphics will be written in Postscript format, the language understood by our printers, instead of the format understood by the windowing system. Then specify a file name for your postscript output.
gnuplot> set output 'myfile.ps'
Then write your plot to the file by replotting.
gnuplot> replot
To send your Postscript file to the printer, use the lpr shell command, (OPTIONAL)
$ lpr myfile.ps
If you would like to continue working with your plot in a graphics window, you will need to return the output and terminal settings to normal by typing
gnuplot> set terminal x11
gnuplot> set output
A great tutorial is here
On windows, you can
set terminal windows
for the output to a window. Next for png output,
set terminal png
This should work on the native windows gnuplot binary.
