MATLAB App Designer fetch data from .m file

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
