Plot each collum as a graph

[dan07]

Hello...

I have a simple problem, but I am not able to solve it.

I have a ascii file with 10 columns and 50 lines each column. I need to load this file and plot each column as a individual graph.

My idea: Read from spreadsheet -> Index Array -> Array to Cluster (cluster size=10) -> Unbundle -> wire each graph to each cluster

Did not work!!! Where is the problem?

A second way to do this is: after load the ascii file, transpose the data, converting each column in one row, and apply many Array subset and wire each graph to each array subset. But I am avoiding this because this way I will need to create 10 array subset.


Thanks

Daniel

Hi Daniel,

your idea sounds good, but you can connect your array directly to the graph. Can you upload your data file and your code, or a picture of your code?

If you intend to have 10 different graph indicators on your panel, then you just have to use an index array function, expand it to create 10 outputs (I bet you missed that property... ;)), then wire each output to each graph. Of course, don't forget to wire also the first column input with a zero value, to tell LV you want to extract the colum data.
You could also have a single graph indicator showing all the 10 curves. Since your data are organized as colums, transpose the 2D array first, then wire it directly to the graph.

Mike... attached is the VI and a TXT file with my data....

Chilli, I don't know how to set up only one index array to plot 10 graphs from one array, 1 graph per column.

Sorry people, I am a beginner user.

Thanks

Daniel

Hi Daniel,

see the attached example picture please.

Just point your mouse cursor on the index array function icon, then click on the handle that appears and drag to display the required number of outputs.
