<div class="moz-cite-prefix">Hi Adam,<br>
<br>
the rqt GUI has a 2D plotter rqt_plot that can plot numerical data
from messages.<br>
It is very similar to rxplot, but there is no restriction (as far
as I know) on how many variables can be plotted. It's just
dependent on you CPU power...<br>
rqt_plot has three different drawing backends selectable from it's
configuration menu:<br>
- qwt plot (fast, but not using message timestamps and needs
python-qwt bindings)<br>
- pyqtgraph (fast and needs pyqtgraph to be installed which is not
in the repos)<br>
- matplotlib (slow but always available)<br>
<br>
Hope that helps.<br>
<br>
Cheers,<br>
Dorian<br>

<div>Hi all-<br>
<br>
</div>
I'd like a tool that plots a series of joint
trajectories. In my work, I continuously re-plan
motions, meaning I need each trajectory to spline
smoothly at a particular time with the previously
commanded trajectory. Having a graphical tool to verify
that this is happening correctly would be very useful.<br>
<br>
</div>
Has anyone already written such a tool?<br>
</div>
Otherwise, I guess I'll start getting familiar with rqt and
matplotlib...<br>
<br>
</div>
<div>By the way, rxplot is not sufficient because it can only
interpret one number per message.<br>
<br>
</div>
Thanks!<br>
