How to i reset/clear an figure in app designer?

451 views (last 30 days)
I tried to write
app.UIAxes.cla;
or
cla(app.UIAxes)
but it doesn't do the job.
Yes it clears the figure, but when I replot something, in the same figure, the old data is still there.
How can I remove this previous data/plots?

I have the same problem.
This is how I plot the data in the first button pushed function
hold(app.UIAxes);
plot(app.UIAxes, x_data, y_data)
After this I tried in another button pushed function
cla(app.UIAxes)
and
app.UIAxes.cla
both is not working.
I am using Matlab 2019b

You also need to specify what kind of hold you want.
Your code is:
hold(app.UIAxes);
Which toggles hold between "on" and "off" and thus could very well be contributing your observed behavior.
You need to specify "on" or "off" as follows:
hold(app.UIAxes,"on");
or
hold(app.UIAxes,"off");

Found the solution.
cla(app.UIAxes)
worked for me.
Befor I got an error: "Reference to a cleared variable app". This was because of a
clear all
. Without it, everything is fine.
