PLUS SIGN on rqt_plot

Dear users,

I restarted rqt_plot and simulation several times, but the topic cannot be added in rqt_plot
What might be the problem?

best regards,

Hi @kailin.tong,

Kindly advise the exercise or example you are trying to do so that we can help you faster.

you can only add simple messages like Floats, Vectors etc. So in this case you have to specify what you want to see. For example
/joint_states/position
or if you just want the x variable:
/joint_states/position/x
for velocity and effort this:
/joint_states/velocity
/joint_states/effort
