rxplot not found

I've installed Indigo on Ubuntu 14.4 and I'm doing the rosserial IR ranger tutorial. When I execute

rxplot range_data/range

I get

rxplot not found.

I gather this command has been superceded by rqt_plot. If so what would the proper command line be.

Thanks

RoboBill

rqt_plot is supposed to be a drop-in replacement for rxplot in most situations. Try:

rqt_plot range_data/range

Good morning

Thanks for the clarification. I did get it to work... sort of. I first got this:

[DEBUG] rqt_plot.plot: import of PyQtGraphDataPlot failed (trying other backends)

Then the plotter came up and displayed my data (way cool) But I'm curious about that initial error. What does this tell me?

BTW instead of using the IR sensor spec'd in the tutorial, I'm using an SF02 from Lightware rotating on my "open source" platform found at http://diydrones.com/group/ardurover-...

Thanks

rqt_plot is capable of using multiple plotting libraries; that debug message just indicates that it wasn't able to find the PyQtGraph plotting library, and used something else instead (probably matplotlib).
