Dear all,

I'm trying to display a set of a calculated values from a data set as a text box in a figure with the plotted data in the following way (note that the figure, axes, and plotted data are already displayed at this stage in the code):

mTextBox = uicontrol('Style','text');
set(0,'DefaultTextInterpreter','tex')
set(mTextBox,'String','test V_o\n \alpha')

What I expect now is Vo (with a subscript) and a Greek lower case letter alpha on the next line, but the TeX string doesn't get interpreted and the string "test V_o\n \alpha" is simply printed in my figure.

Alternatively I have tried set(mTextBox,'String',sprintf('test V_o\n \alpha')) which prints "V_oc (next line) [square]lpha", since TeX cannot be interpreted by sprintf .. so this doesn't do want I want either.

Does anyone how to solve this problem or is not possible to interpret TeX strings in uicontrol?

Thanks,
Jimmy.

PS I know that 'tex' is the default value for 'DefaultTextInterpreter' but since I switched it a few times earlier on in the program I had to put it back to 'tex'. Also, setting it to 'tex' again should not make a difference...

Check out my uibutton:

ushbuttons-with-better-labels>

(Watch out for wrapped URL.)

Even though it is primarily written to create button uicontrols, it can
also create text boxes.

text uicontrols are very limited, and cannot display tex/HTML formatting (at least not out of the box). Instead, use the text(...) function.

Thanks a lot for the tip, I didn't know about this difference between text and uicontrol. Something like this did the trick for me (rather than using uicontrol):

text('Position',[45 235],'String',['test V_o'; '\alpha'])

Note that it is not possible to get \n interpreted as a line feed with text; that's why I put the different lines for the printout in different cells of a string array.
