rqt_plot: Very high CPU consumption when using MatPlot #219
Comments
|
I don't maintain that plugin but I will take a stab since I have heard @DorianScholz discuss similar comments before. He is aware of MatPlot's limitations but it is still made available as the first option since it will be easily available to all users. Have you tried installing one of the other 2 options mentioned in section 1.4 here: http://wiki.ros.org/rqt_plot? |

The problem is that the matplotlib draw method needs lots of cpu time. So I made a workaround to only redraw the plot when new data has arrived. This will help for your case, but not with general performance issues in matplotlib. So use of pyqtgraph is still recommended... |

I know MatPlot consumes the most CPU of the plotting options. Still, it appears wrong that opening 2 plot dialogs consumes a full core on a i7-4800 CPU without even displaying any data (at the time I tried, nothing was published on the topics used in the plots).
The text was updated successfully, but these errors were encountered:
