Hi!
I am trying to plot a topic **/mytopic/taskSpace/position[0]** using rqt_plot. My ROS version is Indigo and I have Ubuntu 14.
When I type in the console **rostopic echo /mytopic/taskSpace/position[0]** I can see the values, but when I make
**rosrun rqt_plot rqt_plot /mytopic/taskSpace/position[0]** The values are not plot. Also there is not errors in the console. Even when I add again the same topic, the console shows **PlotWidget.add_topic(): topic already subscribed: /mytopic/taskState/position[0]**
I don't know how to solve this and it would be very usefull for me since I need to plot a lot of topic in order to check my code.
Than you so much!
