control references and XY graph

[saradhi]

hi there,
I was wondering if somebody can help me with passing data to a " XY graph
" not waveform graph [ in a main VI ]
from a sub vI using the concept of a control reference..
p.s: I dont intend to flatten data .
It works fine with waveform graph but there is nothing to show ( even
examples ) me how to do it with XY
graph.
thanks.

I don't see any problems here using LabVIEW 6.0, and I'm wondering if you're
having trouble with a Variant input or something.

Here's an example of a subVI that spits data into a main VI's XY Graph by
way of a control reference:

thanks
and you said it right. that was the problem.

[whatever]

In the example, why is the control reference outside the case statement, since the graph
is only updated when plot=true the ref belongs inside or did I miss something?.

That xy.zip is no longer there. Can someone post it back?

Thanks!

Hello!  There is an example sub-VI that passes a graph to a main VI posted in this forum. 

Please post back if that is not what you are looking for.

I got it working now but thanks anyway. Reference is better than globals but trickier.
