update data to wavechart from refnum

[ericyuan]

Hey,

So i want to display the wavechart form from another vi, and i tried to use wavechart refnum build the connection between those two vis, but

i cannot find out any properties in the node for me to send data in? Is there anything wrong? I did the table updating with the same method and it works.
Thanks in advance for any suggestions

The Value property!

I actually tried the value property, I can see some data plot on the chart, but obviously not the right one as all the value is 0?

should i add some other things between the random generator and the value input port as i saw the red arrow on it?

It might have been related to the way the waveform datatype was defined.  The terminal being brown shows it is still a waveform type.  And the property node in your VI shows Value in purple making it a variant.

When I tested it on mine, I didn't create two VI's, I just tested it in one.  So I create the property node from the chart itself, then unlinked it from the chart.  I wound up with an orange color on the Value property and it worked.
