To plot a curve, use 'set_plot(value, label)' where 'value' is the value you want to plot and 'label' is a string corresponding to the curve label. You can use the 'set_plot' function in the following function ('user_realtime_plot') or anywhere in your code, provided you add the include '#include "user_realtime.h"' in the corresponding file. Using 'user_realtime_plot' is still useful to structure the code, avoiding to put the 'set_plot' function everywhere in the code. However, using 'set_plot' in other files can be faster and is especially relevant fot C++ code where some internal variables are private and cannot be used outside the corresponding class. To plot different curves, you must use different labels (otherwise, some curves won't be plotted).

example: set_plot(mbs_data->q[4], "q4 [rad]");
