I recently got pyFoamPlotWatcher working. When I am viewing the plots of residuals, gnuplot zoom functions with the mouse wheel don't seem to work. When I try to zoom with the mouse wheel, I get warning outputs in the terminal window as such:

line 0: warning: Skipping unreadable file "/tmp/tmpdcyvzy_t.gnuplot/fifo"
         line 0: warning: Skipping unreadable file "/tmp/tmplgy7lkmd.gnuplot/fifo"
         line 0: No data in plot

or I may also see this:

line 0: undefined variable: inf

Zoom functions in gnuplot work fine otherwise, when plotting other stuff outside of pyFoamPlotWatcher. So I don't think it's an issue with gnuplot.

Note that I'm using OpenFoam 2.4.0, on OpenSuse 13.2, Gnome 3.14.1.

Does anybody know why this is not working properly?

Thanks in advance,
M Ridzon

PyFoam uses a third-party library that controls a Gnuplot process. To allow continuous updates of the graphs it has to manipulate the event loop. This probably breaks some of the interactive features of Gnuplot

Hmm, that's unfortunate. I guess it is what it is though. Thanks for the feedback.
