Stop it.

What I am trying to encourage you to do is to actually write some code yourself and not always ask for the solution. This forum does not exist to do all of the work for someone. You've already been given a perfectly viable solution to your question and you can take it or leave it. All of the various options for displaying data in a chart or multiple charts are shown in the shipping examples and in the tutorials you've been pointed to.

this is a forum and i am free to ask , u can answer it or ignore it
i did not ask u to do something for me all what im asking was in my previous question !!

Do you have to see all graphs at the same time?

Maybe we could consider some other approaches to the solution.

Good morning
Yes this is what i need !! some times i aquire only 4 channels at the same time , some times 10 u know!!! that would be 15 channels at the same time ..but by default i wanna see 20 graphs...if there is no another approach , i would stay with 10 graphs only !!! 🙂
The main idea is  : let the student choose the # of channels he wants.......(all voltage channels , EMG , force , oscill ) and he might choose up to 20 at the same time!!

So you would have a radio button to select which channels you want.  And from that you could index which waveforms to send to the graph.

Since you know which waveforms are going to the graph, you could also find out the sizes of each array (waveform) and determine the largest size.  That could be used to set your x-axis. 

Then you combine the active waveform before sending them to a Waveform Graph.

How does that sound?

Sounds perfect !! so should i make a radio button for each channel ?
Dont give me solution , just tell me how can i proceed step by step (most likely the functions i have to use)
thank you Joe

To avoid crowding up the Front Panel, I would use a Tab contro which has a TAB for configuration / setup.  I would use a Cluster which contains radio buttons for all of the channels (waveforms) that can be monitored.  Make sure they have distinguishable names, because you will unbundle by name later.

Try this and we'll catch up at the next step.

Hey Joe , just a questiopn before i try ur suggestion!!! must i clear my graph to have only one by now ? or must i use the VI you did ? or the one i had before ?
thank you

[Ray.R]

It depends on the behavior that you want.  You can clear a graph by wiring a contant (array of doubles).

Have you decided how you want to proceed?  We suggested many things... 😉

This sounds good so we go from here !!! so this VI is a good start ?
