Hello everyone. I'm new in this comunity and it is my first question. I'm struggling with this problem and I don't know how to solve it. Thank you in advance for your help.

Problem: I have an infinity plot inside the while 1 cycle that plots an operating deflection shape (ODS) of a structure subplot(4,1,[3 4]) based on the selection of a point on the Hsum curve subplot(4,1,[1 2]). What I would like to do is interacting with this figure while the plot is moving in order to have the possibility to select a different point inside the Hsum curve and have the plot of the new data points into the figure. I was trying to solve this problem using a pushbutton (see the commented lines) that restart the for cycle and enters in the if q==1 for the new point selection.

Unfortunately it doesn't work properly and I think it is not the best way to solve the problem.

Can you give me an advice on how to solve this problem? Thank you
