programatically label xy graph

[jon_mcbee]

is it possible to programatically label an xy graph, updating the label using a property node everytime the graph updates?

[falkpl]

prbably better to use the caption instead of the lable for labling a graph (since the lable is user for many other things keeping it constant is a good idea), but this is a property node caption->text

Hello,

  I have the same issue about programmatically changes the label with a property node, it does not work, I get error 1073. So I am changing the caption, which works. Any ideas what is going on?

Regards

Kaspar

You cannot change a label at run-time. The description for the error code says:

 This property is writable only when the VI is in edit mode, or this method is available only when the VI is in edit mode.

Think about it: If you change a label at run-time, how would something like an event structure work?
