I am the same person of the previous question. So I am trying to design an app which, when I click on the button, a circle is drawn in the pannel. This is the code I have written to let this happen:
And this is the result:
As you can see, the circunference is deformed. So, to avoid that, to have the pannel gridded and to hold on the graph for future simultaneous plots, I add axis equal, grid and hold on in the code (as I would do the same for the matlab command window) as you can see below:
When I run the app and click the button, appears the same deformed circle and an extra window (figure 1 ) with nothing on it as you can see:
How can I get rid of that annoying extra window (Figure 1) and how can I achieve axis equal, hold on and grid commands to be executed?
Thank you very much!
