Daniel,

Thanks for the reply. I don't understand French but your picture shows you suggest I use Label : Value to get the dynamic value of the angle.

I actually want to do more than that. By using a text object we can have dynamic values with more comments and algebra expressions. But now we can only 'attach' the text object to some point by using the object's Position property set to that point of attachment.

It would be good if we can directly attach the text object to the Label property.

You can have expressions such as

The value of %n is %v

as a Caption and in the beta 4.0 version you can also have eg

$ \sqrt(x) $

I tried this in the attached file but it doesn't seem to work!

I think it would be useful if captions had more of the properties of a text box or at least could do what lewws suggests.

Could the angle symbol be included in the drop-down list?

This won't work:

The value of m is %m

This will work:

The value of %n is %v

What am I doing wrong?

For %n is n the name of the object to which the caption belongs and for %v is v the value of that object?. Is v supposed to change dynamically if n changes?

Also if a = 4.32 do I enter "the value of %a is %4.32"? but then if I change a the caption will be misleading.

Don't use %a, %b, %c, %d, ... etc.

%n and %v are the only things that work.

Thank you murkle, at last I understand.

%n returns the name of the object to which the caption belongs.

%v returns the value of the object.
