how do I initialize a XY graph, in a running process

[kliner]

Hi

we have a question concerning a XY graph.

we have a running process and as a subVI , we can see the XY graph.

we didn't figure out how to initialize it every time we call the subVI.

thank you in advance

What do you mean by initialize, do you just want to clear the graph, or do you want to initialize it to a known value, whichever you want to do, all you have to do wire an emty array to a local variable or property node before you start the process in the subvi.

may I ask how to clear the graph 🙂 ?

As I said wire an empty array to a local variable or property node

oops...

or another way would be to use an invoke node and reinitialize it to default.

Please see the following program attached. The subVI writes data to an XY Graph. The Main VI calls the subVI and then when the subVI finishes excuting, reinitializes all values on the subVI (the XY Graph in this case)to default.

Hope this helps!

The invoke node to reinitalize the graphs (and tables too) to a default (clear) works really well!  Why isn't this described in the on-line help....I learn something new everytime I read this board!

Regards to all....

It is described somewhere. LabVIEW is such a rich environment, that not everything can be on page 1 of the documentation. 😉

(In this case, you need to search for Reinitialize instead of Initialize to get to the right place in the online help. So, yes, it's a bit buried...)

If you have ideas on how to improve the documentation, feel free to give some constructive feedback at the Product Feedback page. 🙂
