PyQtGraphDataPlot and MatDataPlot fail to load
hallo,
as soon as I launch rqt_plot using
rqt_plot "topic name"
or
rosrun rqt_plot rqt_plot "topic name"
I get the following errors
rqt_plot.plot: importing PyQtGraphDataPlot
rqt_plot.plot: import of PyQtGraphDataPlot failed
rqt_plot.plot: importing MatDataPlot
rqt_plot.plot: import of MatDataPlot failed
The plotting tools start but I miss the interface buttons. Moreover both the x and y scale don't change according to data. I am using Fedora 18 and groovy. I don't know where to start for debugging because I have never used python. Thanks for your help.
Can you describe the command you used to run
rqt_plot? You can add it to your your original question. Also what version of rqt_common_plugins you're using? You can get the version by$ dpkg -p ros-groovy-rqt-common-pluginson Ubuntu but not sure about Fedora..I don't know how to retrieve the version. Sorry but It wasn't me who installed ros on this machine and I don't have dpkg on mi Fedora distribution. Do you know any other way? BTW in the package.xml of rqt_plot it says 0.2.10.
Actually, I'm seeing
PyQtGraphDataPlotimport failure on 1 of my machines too (Quantal 64b, Groovy, rqt_plot 0.2.14). Changing the loading order by modifying plot.py still yields the same failure, which indicates order doesn't matter. I'll ask the author.
