Why don't my xy graph update when it is not visable?

I have an XY graph on my front pannel and when the raw data is displayed the graph isn't. But when you go back to the graph the data doesn't update unless you leave it visable. How can I get it to update even when it is not visable on the front pannel.

Hi Cvis,

I am a little bit confused by what you said. Can you make it clearer?

I know that problem. If you have e.g. a tab control and update a graph while
your graph is not visible and then go back to the graph, you will see
nothing.
I do not know a good solution fo this problem. I solved it by updating the
graph always when I switch back to the graph

I would like to guess as follows:

1. How is it when the procedure of visualizing and update
is put into a sequence structure? There is a possibility
that update occurs after visualizing flag is positive
during some period in your program.
2. How about the graph characteristics are? Isn't it set
so as not to update?

Hope to help,

I had a similar problem recently and solved it by wiring an attribute node
to make the chart not visible for a short time, and then visible again.
This seemed to do the trick. It seems the draw routine in LabVIEW is a
little picky as to when it updates graphs.

I don`t know if this works with tabs, I`m using LV 5.0

good luck
