output from PlotWindow

[Tony Shepherd]

I have a plugin that outputs graphs (PlotWindow objects) to the screen using
PlotWindow.show(). There's no method in PlotWindow to save these figures -
in particular I want an encapsulated postscript (eps) file.

Currently I am saving the plots as text PlotWindow.saveAsText(), then
importing to another program that lets me save out as .eps.  

Is there a better way?

thanks

Hi Tony,

You could use the EPS Writer
   http://rsb.info.nih.gov/ij/plugins/eps-writer.html

I fear that you won't be happy with it, however:

The Plot Window uses pixel graphics. If you want to include
your plot into any document to be printed or converted to PDF,
you should have vector graphics.
Therefore, it is much better to export the plot values as text
and use a program such as gnuplot: http://www.gnuplot.info/
With gnuplot, you can get eps output with
"set terminal postscript eps".
It should be possible to control gnuplot from a macro using the
exec macro function of ImageJ.
