Hi I have a function in callback of app designer that returns few figures. How do i plot them in UIAxes. I know that it is possible to use plot(app.UIAxes, x, y) but I havent got access to x and y coordinates of this figure.
Thank you for all your help

Those are the x and y coordinates. Why don't you have access to them?

my function generateTrack returns only the figure not the coordinates. It possible to access this x, y coordinates from the figure level or i need to change the function so that it would return coordinates?

It's possible to extract the data from the figure but it's much better to return the values from the function.
function [___, x, y] = generatTrack(__)
...
x = XYVAL(:,1);
y = XYVAL(:,2);
plot(ax2,x,y);
end
or
function [___, XYVAL] = generatTrack(__)
...
plot(ax2,XYVAL(:,1),XYVAL(:,2));
end
