I've a plot function in .m file. Can I plot the same figure inside App Designer with data being fetch from .m file continuously? How to achieve this?
For example, Suppose I've a test.m file and I want to plot it in App Designer.
function test
clc
global T
x=(0:.01:16);
y=sin(3*x);
T = figure(1);
hold all
Dx=50;y1=-1.2;y2=1.2;
for n=1:1:numel(x)
plot(x,y);axis([x(n) x(n+Dx) y1 y2]);
drawnow
end
end
Or Is it only possible to have a button in App designer and on clicking it, pop up figures appears?

if you call this function in app designer it will create an outside figure so you need to edit it a bit
You need to remove
T = figure(1)
hold all
add a UIAxes in you app
for hold on use
app.UIAxes.NextPlot = 'add';
Change this
plot(app.UIAxes,x,y);
app.UIAxes.XLim = [x(n) x(n+Dx)];
app.UIAxes.YLim = [y1 y2];

Can I not plot without making any changes in test.m file?
All necessary changes need to done in app designer only. Also, I want to call test.m in app designer, not copy the logic in app designer.

if you want to plot it inside the app designer figure, then you need to make changes
if you just want to open a new figure, just write m file name in some button callback or in startup function. remember m file which you are calling must be added to matlab path
