I need to create a graph in App Designer, but the graph is too large and I need to shorten it, I try to do this using Edit Numeric, but an error occurs Index exceeds the number of array elements (0)
function depthButtonMenuSelected(app, event)
title(app.UIAxes, 'Obj3010')
xlabel(app.UIAxes, 'zone')
ylabel(app.UIAxes, 'Ob')
app.Obj=app.Obj(app.a:app.b); % Index exceeds the number of array elements (0).
plot(app.UIAxes,app.d,'LineWidth',5);
end
%
function aEditFieldValueChanged(app, event)
app.a = app.aEditField.Value;
end
function bEditFieldValueChanged(app, event)
app.b = app.bEditField.Value;
end

it is because app.Obj is empty. it has no value.
First check what is app.Obj? maybe what you are trying to do is
app.d=app.d(app.a:app.b);

see the attached app button callback
app.EditField_name.Value = app.a;
Also it is not necessary that max(app.d) is less than app.d length or is interger
For example
app.d = [1 2 6 4];
Now
app.b=max(app.d); % app.b is max value of app.d and not max value index
so app.b is 6 and now your code
app.d(app.a:app.b)
wil try to access app.d from 1st index to 6th index which doesnot exist
to get max value index see help of max
