The Axes Tag keeps on deleting....

Every time I open the project - the Axes Tag is empty. That causes the background picture I it to not appear.
Any idea?

As reply to your comment to Image Analysts answer:
You can fix this by the shown method to set 'NextPlot' to 'add':
h = axes('tag', 'theTag', 'NextPlot', 'add');
Then new object added by so called high-level graphic routines do not clear formerly created objects and do not reset some properties of the parent object anymore. I create all AXES objects with this property and whenever I want an already existing object to be deleted, I do this explicitly. The less I let Matlab guess what I want, the less chances Matlab has to make mistakes.
I follow the same principle for low-level functions also: The high-level function plot() creates a line object. calling line directly is faster, has less side-effects, but it is less convenient e.g. for setting markers. But even then specifying the axes handle as 'Parent' property has advantages instead of relying, that the wanted axes is the current object: When a TIMER callback activates another axes, the results look very confusing.

IA: I did - no answer :/
But thanks.
As long as I do not turn on the GUIDE - all is good. The problem happens when I turn the GUIDE on - then the Tag is gone.

It should answer - they have an automated/computerized phone answering system. Try calling them during normal business hours.

How are you opening "the project"? In GUIDE? And then you double click on an axes to bring up the property inspector and the tag property is empty? That seems weird or impossible.

Guys, it looks like you also encountered my problem.
Jan, I'm not sure if you saw this behavior or not (not sure what this code is for) - but your questions are valid and that is the question for the answer I'm looking for - Why should this happen? End more - how to fix this?

You could probably fix it using GUIDE. I use GUIDE and that never happens to me.
