Hello,
The below code is working in Matlab but I am unable to execute this same thing in Matlab app designer.
fig = figure('Interruptible', 'off');
ax1 = subplot(1,2,1);
ax2 = subplot(1,2,2);
fig.WindowButtonMotionFcn = @(~,~) [];
t = timer('Period', 0.1, 'ExecutionMode', 'fixedRate', 'TimerFcn', {@mouseMotionCB, ax1, ax2});
start(t)
ginput(1)
stop(t);
delete(t);
function mouseMotionCB(fig, event, ax1, ax2)
currentPoint1 = ax1.CurrentPoint(1,1:3);
x1 = currentPoint1(1);
y1 = currentPoint1(2);
if (ax1.XLim(1)<x1)&&(x1<ax1.XLim(2)) && (ax1.YLim(1)<y1)&&(y1<ax1.YLim(2))
fprintf('This is axes 1, Current Point is %f %f %f\n', currentPoint1);
end
currentPoint2 = ax2.CurrentPoint(1,1:3);
x2 = currentPoint2(1);
y2 = currentPoint2(2);
if (ax2.XLim(1)<x2)&&(x2<ax2.XLim(2)) && (ax2.YLim(1)<y2)&&(y2<ax2.YLim(2))
fprintf('This is axes 2, Current Point is %f %f %f\n', currentPoint2);
end
end
I have created an 'app1.mlapp', but this code is not executing in app designer .Can anyone help me with this?

ginput() is working , after the mouseclick values are printing in workspace.
It not displaying the values at figure window.
Error : Too many input arguments

Please see the app attached with the script for the callback function. Let me know if this addresses your problem.
Note, I also attached an app for the pop up window if you were interested in using this instead.

I changed
brush(app.UIAxes,"on")
to
brush(app.UIAxes,'on')
and it worked for me in R2021b (see attached).
Is there a reason crossair.mlapp doesn't work for you?
