Set text in GUI figure axis

Hi,

I would like to annotate a plot in an axes in a gui built with guide.

in the text call how do I specify the figure (for the gui) and the axis I want it to plot in?

Currently if I simply write:

      text(xtp_ac,ytp_ac,'ATF-01');

I get it plotting correctly on the first call, but on the next update it doesn't plot and it opens a new figure.

I think I need to do something along the lines of:

text('FigureHandle',____,'AxesHandle',_____,xtp_ac,ytp_ac,'ATF-01');

however when I do this the figure just continuously opens and closes a couple of times a second rendering it useless.

The program I have written plots an objects position as it moves around over a map. I want to be able to give it a label to identify it as I have more than one plotted at the same time.

Thanks in advance.

A look through the documentation for TEXT properties shows the Parent property, which lets you specify an axes:

ax=axes;
text(0.5, 0.5, 'My text', 'Parent', ax);

To give an identifier to a TEXT you create, consider using the Tag property.

Specifying the axes handle is enough, because this defines the corresponding figure uniquely already.

Thank you to both of you!
