XY graph collecting data

[KoenR94]

Hello,

I'm trying to collect the data from a XY graph, for further purpose in my program. 

But when the graph doesn't get any information anymore it appears to clear its chart.

I'm using this vi as a subvi if that is any help, that's why I'm using while loop so forget that one.

Or isn't there anyway to collect the data from it and I simply have to save it in a 2D array?

Hi Koen,

THINK DATAFLOW: a graph only displays data!

You have to collect the data on your own in a shift register.

Your subVI might look like this:

Hi Gerd,

You actually improved my sub subvi, haha.

I just added it because it would be easier to understand.

Anyway, so the best thing to do is just to build it in an Array rather then predefining it as a Cluster?

Hi Koen,

you can collect data in a cluster too, but using arrays for such tasks is (usually) easier...

Hi gerd,

I converted it to arrays as you proposed though it still doesnt work.

In the attachment is the subvi which will process data.

Hi Koen,

what is "still not working"?

In your picture you wired a scalar value to the SaveReport-VI, so I would not wonder when there is just one data value in your report (instead of an array of values)...

Hello Gerd,

I'm trying to save the data acquired from the apply filter vi to the savereport vi.

Where in the savereport via the array will be clustered because that will give the nicest result.

As the picture says, the scalar value you see isn't what it is, it is a stack of wires. Otherwise it would become really messy.

Hi Koen,

hiding elements in the block diagram is considered very bad programming style, especially stacking wires behind each other!

You should use AutoCleanup more often (ctrl-U)!

You should also get rid of all local variables in your SaveReport-VI, as they lead to race conditions...

I don't get the point here...

Hi gerd,

I'm normally neither a fan of the stacking, though it is absolutely necessary, otherwise 10 different wires will just go to right.

Only way to fix this wire stacking is using a cluster, but will this make any sense?

I removed all the local variables now, though it didnt work.

I use it clustered because i like how the XY graph gets represented.

Why i wanted it this way? because it gives a better view for a report in my opinion.

P.S. Thanks for all your help in advance!

When those 10 values have the same datatype you can use an array, otherwise use a cluster.

Yes, that makes sense!

As long as the data remains the same you will get the same plot. It doesn't matter if you're using clusters of arrays or arrays of clusters!
