need help with multiple plot xy graph

[johanneshoer]

Hello,

I need your help with my multiple xy graph.

I have don it like in the examples but it does not work. Instead of two plots, there is only one plot with the two data arrays mixed.

What have I done wrong?

 I think I found out....

There needs to be two data arrays and one more bundle...

Is it ok like that? I doubt it... although it works

Is there a better way??

this one is really related to that...

I want to get rid of the two arrays.

I simply joined these two arrays into one array and I select an array subset for the xy graph but that does not work.

Now the two data arrays get mixed again in the chart.

I can't see what is wrong. I have tried many things like indexing the array before the xy graph, directly wiring the array to the graph etc. nothing worked.

Please help.

finaly... after 100000 tries.

It's not yet working 100% correcty, but the chart is now behaving like I want it!

Dear LabVIEW experts,

I would like to know your opinion about my last version. Is it ok or are there stil things to improve?

I wonder why it is so complicate to display multiple data in a graph (indexing the data array, bundling, building the array again)

How much resources (memory & cpu time) does "delete from array" need? I could imagine, that it stresses the CPU, if I have a large array and if I delete the first row.

Are you able to open my 7.1-VIs with your LabVIEW versions (8.0, 8.5, 2009, whatever)?  

Johannes
