Whenever you want to change the text label, just put this code

yourString = sprintf('The value = %f', someDoubleVariable); % or whatever you want.
set(handles.textLabel, 'String', yourString); % or whatever tag you have instead of "textLabel"
drawnow;  % Use draw now if in a fast loop.

It can go in whatever callback or loop you want, basically whenever and wherever you want to change the text on the label control.

can you give me an example for editing the XLable or XLim ?

% Create sample data.
x = -50 : 50;
y = sind(x*30);
plot(x, y, 'LIneWidth', 3);
grid on;

% Make x axis go from -10 to +30
% instead of -50 to +50:
xlim([-10, 30]);
% Give a label to the x axis:
xlabel('This is the x axis',...
  'FontSize', 20,...
  'FontWeight', 'bold',...
  'Color', [.7, 0.3, 0.9]);

You can use the Property Inspector if you use GUIDE (right click on the object whose properties you want to modify, select Property Inspector, look for the field to change in the emerging window).

Otherwise, you have to use set and get commands to perform changes in any object of your GUI.

where i can place the set and get in the code, openfcn ? i can't edit the Xlim or Xlable (for an axes ) from the Property Inspector

[Sean de Wolski]

Do it in the OutputFcn.

You can run:

inspect(get(handles.axes1,'XLabel'));

To pull up the xlabel in the inspector. axes1 is the 'Tag' of the axes you care about.

it works with inspect command , but it seems like every time i run the code it will appear ?

i tried this , but it doesn't work

myname = get(handles.axes1,'XLabel'); set(handles.axes1,'XLabel',myname);
