Have you read the answer to his posting? Obviously he cross-posted and got the answer elsewhere

Hi,

I would like to print the plots of pyFoamPlotWatcher.py and tried the following commands.

Quote:
pyFoamPlotWatcher.py log --with-courant --hardcopy
pyFoamPlotWatcher.py log --with-courant --format-of-hardcopy=pdf
pyFoamPlotWatcher.py log --with-courant --write-files
pyFoamPlotWatcher is plotting the data (including courant number) in the X11 windows, but doesn't create any hardcopies (at least I can't find them)! Does anyone know what I'm doing wrong, or if there is another way to create pdf's (without creating screenshots)?
I'm using OF-1.7.1 on Mac OSX 10.6.5 and have the pyFoam(PlotWatcher) version 0.5.4.

The first variant (of course with a logfile, guess you omitted that) should write some PNGs into the current working-directory AFTER you finished the watch wit Ctrl-C. The second variant writes nothing (but if there was a --hardcopy it would force gnuplot to write PDFs). The third variant writes the plotted data as timelines to some textfiles (see the *.analyzed-directory)

It is not a Mac-problem per se (I develop that stuff most of the time on such a thing). Is there any additional output after stopping the watcher?

If you want the residualplot in pdf Format to be saved in the work directory, just use :
pyFoamPlotWatcher.py log --hardcopy --format-of-hardcopy=pdf
