Dynamically Changing Number of Channels in Chart

[jpo]

Hi,

I have a simple question about a labview programming issue. I am
trying to modify an NI Example program for demonstrational purposes.
I am using the Multi-plot real-time chart example program (link below)
from the NI website. I have changed your example for the chart to
display the data in the stacked plot mode. How could I modify it to
vary the number of traces dynamically. Is this possible? My goal
would be to use a series or radio buttons to control viewing 4, 8 or
16 channels, in real time. All of the code and programs I have seen
have channel display statically in the begining setup. Is there a
property node of the chart that controls this?

Thanks
John

To accomplish your goal, the example VI needs to be modified a little bit. I've made one such modification and attached the modified file. I hope it helps. Please note that nothing shows on the Front Panel Until you press one of the control buttons.
