Plotting simultaneously to multiple axes in GUIDE

Hello,

I have two individual external functions that produce "dynamic" plots that are animated using for loops. In my GUI code I have three axes. I want to simultaneously plot these "dynamic" plots in two specified axes when a button is pushed and these functions are called. I know that one would normally use set and handles.NameofyourAxes; however, since these are external functions that would - when run on their own - produce figures in which the dynamic plots run. Right now I am only able to display one of the functions in whatever axes the user clicks. How can simultaneously run two external graphing functions and control which of the three axes they plot to?

I have also experimented with gca, but I have had no luck. Thank You!

If the external routines use figure() to create a new figure each time, then you cannot force them to write the graphics into the place of your choice. If the external routines use gca() or just go ahead and do their plots then you can control which axes they write to by using axes() before invoking them.

However, if the external routines just go ahead and plot in whatever axes is current, and if both of them are using something like timers to trigger updates, then you cannot make them write in the correct axes: routines that do that are mis-written. (All routines that use timers to update should take care to save the target axes and take care to write to that axes in all graphics operations.)

It is difficult to say what would work without seeing how the external routines are handling their graphics.

Hello,

Thank you for your reply! The external routines just go ahead do their plots and I am not using timers, figure, or gca. How would you use axes() to target a certain axes? Also just to be clear you would use axes() in the guide script right before calling the function? I have seen something like

set(figure_handle,'CurrentAxes',axes_handle)

What would the figure_handle of a plot created by an external routine even be?

Thank you Again!

If the external routines are not creating their own figure or axes then in your script use

axes(handle_where_you_want_the_output);

and then call the routine.

If the external routines do create their own figures, then there is nothing you can do ahead of time to force them to draw where you want, but afterwards you can move it from the other figure into the place that you want.

Hello, I tried putting that axes line both in the guide and in the external routine by making the handles.ArmGraph (the name of my axes) an input of the function and then typing the line in the external routine. This is correct right: "axes(handles.ArmGraph)"

I have attached my external routine to this comment. Is it possible to change this somehow to fix my problem?

Thanks!
