Hello,
i m trying to give user option to set Y-axis for the plot axis. so user can limit the axis at it own preference
i take two simple Variable data lets say
a = [1 2 3 4 5];
b = [2 6 3 8 5];
plot(app.UIAxes,a,b);
then in "plot" button callback i defined
value = app.YAxisMinValueEditField.Value;
app.UIAxes.XAxis = value;
but it gives error that
"You cannot set the read-only property 'XAxis' of UIAxes."
kindly suggest a solution...currently i m trying only for min value editfield.

ymin = app.YAxisMinValueEditField.Value;
ymax = app.YAxisMaxValueEditField.Value; % I'm guessing this handle
ylim(app.UIAxes, [ymin, ymax])

can u please guide me futther... i m now controlling the axiseditfield via checkbox that user want to input axis aur wish to use default axis.
Now when i start i works fine... plot directly and when checkbox is selected then it plot according to edit field axis... but problem starts when i switch off check box it does not directly plot with pushbutton of "Plot"
function Axis(app)
app.a = [1 2 3 4 5];
app.b = [2 6 3 8 5];
if app.AxisCheckBox.Value
app.p = plot(app.UIAxes,app.a,app.b);
ymin = app.YAxisMinValueEditField.Value;
ymax = app.YAxisMaxValueEditField.Value;
ylim(app.UIAxes, [ymin, ymax]);
else
plot(app.UIAxes,app.a,app.b);
end
end

if app.AxisCheckBox.Value
app.p = plot(app.UIAxes,app.a,app.b);
ymin = app.YAxisMinValueEditField.Value;
ymax = app.YAxisMaxValueEditField.Value;
ylim(app.UIAxes, [ymin, ymax]);
else
plot(app.UIAxes,app.a,app.b);
% You forgot to implement the ylim here
end
