[bijal]

hi

here i want to extract data from the  XY graph . I attached vi which i use for 1D array . how i can use this VI for 2D Array.

Thanks

Hi bijal,

you may use the same approach.

The only thing that changes is the ArraySubset function as it adapts to the 2D array. You can select either rows or clumns from your data (depending how you generated them)...

Exaclty the same but you have to subset array double.

Follow GerdW's example if you want to use graph instead of XY graph.

hi

thanks for solution

but if i do as per solution X- scale is change and give wrong ans.

You mean the X-scale differs from the the original?

Then you have to use a XY-graph as in my post

hi

here i send u my vi.in this vi i use xy graph and use array subset double.but it gives me x-scale differ than original.

thanks

Hi Bijal,

that's not a VI, it's just a huge picture with a lot of whitespace!

- Attach the VI...

- You're working with some ExpressVIs and a lot of DDT wires. Whenever you convert your DDT to something else (like you you) it may also affect the data, hence "changing the x axis"...

Hi

I am facing problem to extract data from XY graph . I need to extract data between two cursors in a graph into an array. I was trying out the method mentioned over here but I couldnt get exact values between cursors.

Thanks

Hi mahesh,

do you think we can debug your VI by looking at a picture of the frontpanel?

What exactly is your problem?

Hi Gred,

   I am attaching my VI...

 I exactly want the values lying between two cursors.and extract them to an array......as I shown in front panel picture....
