Hi guys,
Thank you very much for all the reply! They are very helpful!I have taken some time to merge the matplotlib into ros-gui for real-time scalar data visualization. This is actually a simple version of original rxplot. I think the plot quality is better than qwt:

The image looks great. Is the repository for this plugin available?
And I'll soon implement rxbag in ros-gui.
This would be a great plugin for ROS GUI.
It would be one of the most important rx-tools yet missing in ROS GUI.
May be it would be good to put this directly into the "ros_gui" stack?
I'd like to merge all my code in ros_gui stack. But what shall I do?But before going further, I have some question:
1. It looks like the rviz has it's own dock widget plugin architecture. Is that an overlap between rviz and ros-gui if I make an rviz plugin for ros-gui?
Yes, rviz uses it's own plugin architecture to be independent of ROS GUI.
Actually there is already a rviz plugin for ROS GUI ("rosgui_rviz") - please take a look at the "ros_gui" stack and its packages: https://kforge.ros.org/visualization/ros_gui?p=ros_gui;a=treeIn future we may want to make the plugins compatible between ROS_GUI and RViz, I don't know. For now, if you want to be able to use your code in either, maybe you can keep most of your code in an internal class which is the same for both frameworks and just write small wrapper classes for RViz and for ROS_GUI.RViz and ROS_GUI both use a QMainWindow and QDockWidgets to house their widgets, so I would think that widget code written for one could be used for the other as well. Though ROS_GUI uses a Python QMainWindow and RViz uses a C++ one. Interesting.2. Is the rviz property display widget available for ros-gui?
I don't know - but the existing plugin "rosgui_rviz" runs a full instance of rviz inside a ROS GUI dock widget.It is not currently available on its own in ROS_GUI, but I believe it could be integrated. I plan to publish the API for RViz's property editor widget. You can see a C++ example of how to use the property editor in visualization/rviz/src/test/property_test.cpp. You'll need checkouts from trunk of visualization and visualization_common, build both, then "roscd rviz && make test" to build it.I would hope the property editor widget could be used to edit properties of lots of things in ROS_GUI, but I haven't tried it. Also, I haven't set up the Python bindings to happen for the property editor code yet, I don't know if that will be hard or easy.
This is very useful! But what if both two ros_gui plugins have a same widget? Apparently loading a same widget twice is not efficient. At the moment I don't think there is a communication scheme between plugins in ros_gui. Am I right?Ecto is new to me, I will take look at it. Actually I'm very interesting in the rosh. The ipython integration can help me to analyze the real-time data by Python scripting. Maybe a rosh plugin for ros_gui is valuable?
And I'll soon implement rxbag in ros-gui.Good stuff! I designed rxbag in such a way that it could be included in a larger system, so hopefully that integration should be straightforward.What I really need at the moment is something like rxlab which is mentioned here. Is the development of this package still active?
No, it is not. rxbag is already implemented as a "unit" in rxlab, so you can look at the source to get a feel for how to integrate the main timeline component. Another system worth exploring is Ecto, which is a very well designed tool for quickly and efficiently prototyping and visualizing networks of computation.If you have technical questions regarding either rxbag or rxlab, feel free to email me.
Cheers,
