Basic fitting in GUI axes

I have a GUI containing some axes for plotting data. I would like to use the Basic Fitting routine under the Tools tab of the figure menu on the GUI. However it is greyed out. The only method I can find is to copy the relevant axes from my GUI to a new, separate figure and do the fitting on that. This however is very unsatisfactory. Is there a method of fitting the data directly into the GUI axes?

what do you mean by 'fitting the data directly into the GUI axes'

[Gordon]

Can I use the Basic Fitting routine on data plotted in axes that are part (children) of a GUI?

Are you using an m-file to to this? Or trying to do it interactively? If using an m-file, are you using GUIDE, or creating all the controls yourself with uicontrol()?

[Gordon]

The question is irrelevant. Basic Fitting is a Matlab tool under the Tools tab of the standard figure menu. If you create a figure you will see it. The figure menu is also available if one creates a GUI. Then however the Basic Fitting tool is disabled and I would like to know how to get around this so that I can use the Basic Fitting tool on any axes within my GUI.

So the answer is you're doing it interactively, manually via toolbars and dialog boxes, instead of programmatically in your m-file code via calls to polyfit() and polyval() or some fancy function in the Curve Fitting Toolbox.

I plotted stuff (one axes, and two axes per figure) and it was enabled. Are you sure you have data in the axes? Assuming yes, then maybe you should just call the Tech Support because I can't reproduce. If you can give us some short code to reproduce the menu function being disabled, then we can try it. Something like:

subplot(2,1,1);
plot(1:10)
subplot(2,1,2);
plot(30:35);

Right now, I'm at a loss because I don't see the problem you're seeing. I use R2012b.

Even you have data in the axes, the basic fitting is still disabled

[Gordon]

You are creating a figure using the command 'subplot'. I have no problem with that. What you must do is create a GUI, gui.fig, with some axes on it and ensure that the GUI has the figure menubar on it. Run the GUI with some data for plotting in e.g. the startup function of gui.m and now try the Tool tab of the menu bar. The Basic Fitting submenu will be disabled & that is the problem.

Try setting the figure property 'Toolbar' to 'figure'.

[Gordon]

Doesn't make any difference - the Basic Fitting submenu is still disabled

I am having a similar problem right now. There is a chance that you are dealing with a very large dataset and there is not enough memory to complete this action.

Hi Robert

Um - I don't understand why you are replying to a question originally posed in 2012.
