Early preview: PlotJuggler (rqt_plot and rqt_bag on steroids)


I am currently working on a personal project called PlotJuggler.

To get a first idea of what PlotJuggler can do, take a look ot the following videos.

PlotJuggler is a Qt based application that allows the user to load, search and plot data.
Many ROS user would use MATLAB or rqt_plot for this purpose, but these solutions might be frustrating to use when the data to be analyzed is considerably large.

PlotJuggler is meant to be (hopefully) a better alternative to rqt_plot and rqt_bag, providing a more user friendly interface.


  • Multiplot: add multiple curves to a plot. Arrange plots in rows, columns, tabs and/or separate windows.

  • Zoom: easily zoom a plot. You can lock the X axis of all of the plots.

  • Save/Load layouts: once you have organized your layout, you can save it on a file to be reused later.

  • Complete Undo/Redo: CTRL-Z and CTRL-SHIFT-Z do what you expect them to do! Dramatic “D’oh” reduction guaranteed!

  • DataLoad plugins: easily load CSV or rosbags. More format can be supported in the future.

  • DataStreaming plugins: subscribe to one or multiple ros topic(s) and plot their data live.

  • RosPublisher plugin: re-publish the original ROS messages using the interactive tracker.

PlotJuggler is still in its “alpha” stage and under heavy development. I would like to get some feedback from the community to understand what developers need most…

You can find the code here:

NOTE: you will also need this package too

The video is wonderful. It would a be a great tool for my problems. But a little silly query. How do I launch the application, I cloned , catckin_make and all is well. Not sure what next?

If everything goes well, you should find the executable and the plugins in devel/lib/plotjuggler.

You can run it diectly or if you can’t live without rosrun…

rosrun plotjuggler PlotJugler

Nice work, definitely going to try this out! I see a lot of similarities with another plot tool presented at last roscon: rqt multiplot : . Are you familiar with this one? Just checking to avoid parallel developments of same functionalities.

It doesn’t throw any errors. But when I run it,

rhagoletis@rhagoletis-MS-7885:~/catkin$ rosrun plotjuggler PlotJugler
[rosrun] Couldn't find executable named PlotJugler below /home/rhagoletis/catkin/src/PlotJuggler

Am i doing something silly?

Hi @pvnkmrksk,

Please ask debugging questions on

It looks like the generated executable is named PlotJuggler with two ‘g’. You should be able to run it with: ./devel/lib/plotjuggler/PlotJuggler

rosrun will not find the executable because it is installed in the lib folder and not the bin folder for some reason. To get it working with rorsrun you can change to install in bin
then rosrun plotjuggler PlotJuggler should work

That is not correct. Binaries in the bin folder can be invoked as is since they are on the PATH.

rosrun is being used to execute executables from a package specific folder (which is not on the PATH) which are under lib/<pkgname>. So ./devel/lib/plotjuggler/PlotJuggler should be invoked with rosrun plotjuggler PlotJuggler (after sourcing the setup file from .devel and if the file is marked with the executable bit).

You are right, this was a hacky workaround.
I couldn’t get rosrun to find PlotJuggler without modifying the OUTPUT_DIRECTORY variables :
I must have messed up someting in my config because now it’s working just fine with the current version on master. So please discard my previous comment. Sorry for the noise.

Thanks for the explanation!


both rqt_multiplot and PlotJuggler were announced mostly t the same time.
I guess we may say that they try to solve the same problem in two different ways.
In a ideal world, we might have collaborated, but we probably have different opinions in terms of UI and usability.

  1. both gives the much needed ability to save the configuration/layout once you arranged your plots.
  2. PlotJuggler, additionally, provides multi-window and multi-tabs
  3. PlotJuggler itself is NOT a ROS application. ROS is supported through plugins.

I am happy to receive feedback from the users about that rqt_multiplot does best :smiley: to improve my own application.
