Hello there!

I'd like to use the command vplot in MATLAB AppDesigner, but it doesn't work.

Is it possible to use it? or is there any other option to plot a vector in 2D in AppDesigner?

I could not get the vplot function to work, but there is always quiver.

For instance, if you add a button to your app and give it a callback function you can give it the following commands:

load wind
quiver(app.UIAxes,x(:,:,7),y(:,:,7),u(:,:,7),v(:,:,7));
ylim(app.UIAxes,[30 50])
xlim(app.UIAxes,[85 115])

This will produce a nice 2D vector plot in the app designer (assuming that you already have a UIAxes pane with the name UIAxes in the app):
