show graph that is created in a subvi

[mysticfree]

Thanks!  That link is a good starting point although Dennis' examples had no documentation as to how everything is put together.   So to benefit anyone running into this same problem, here's what I discovered:1) Starting with my sub vi, I created a control refnum to the waveform graph.  This was found by going to my sub vi's front panel controls menu and picking "modern" "refnum" "control refnum".  With that on my front panel, I then right clicked and selected "select vi server class" "generic" "gobject" "control" "wavegraph" "wavegraph"2) Next, I created a property node inside of the while by going to my sub vi's block diagram functions menu, selecting "Programming" "application control" "property node"3) I placed the refnum control outside of the while loop and connected it to the property node refnum terminal.  Selecting "value" in my property node, I connected that terminal to my waveform data line.4) On the terminals of my icon (accessed on the front panel), I added an input terminal for the property node and an output for my waveform graph.5) on my Main VI's front panel, I copied and pasted the graph indicator from my sub vi.  I then added my sub vi function to the Main VI's block diagram.  6) Next, I created a VI server reference by selecting "Programming" "application
control" "VI server reference".  Right clicked on the "Server Reference" and choose "Link to" "Pane" "Waveform plot"7) Connected the "VI Server Reference" to the "property node" of my sub vi icon.  The graph terminal of the sub vi connected to the graph indicator.  Saved everything!  Tested.  All works well!I hope this helps someone.Message Edited by mysticfree on 03-15-2008 11:32 AM

>4) On the terminals of my icon (accessed on the front panel), I added an input terminal for the property node and an output for my waveform graph.
 
I'm not sure I understand this instruction. Do you mean a terminal connected to the Graph refnum? Otherwise, how can I connect a terminal to the property node?

I believe what he meant in #4 is that you create a terminal for the control refnum (which is connected to the property node in the block diagram). Once you have created this terminal, you can wire to it from outside of that VI.
