taking values from an array depending on the elements of another corresponding array

[jyot445]

 Hello,

Here I have attached a text file and I am reading it in LabVIEW and taking the columns of the text file in two different arrays . as you can see in excel plotting there are points in 4th quadrant also. I want to take those points only (4th quadrant) for further display. Can anyone help me in this as how to do it?

p.s. ignore the jsc,voc part.

Hi jyot,

simple as this:

Just some functions: ReadSpreadsheetFile, IndexArray, Bundle. A FOR loop iterating over all points and filtering only those with X&Y<0.

So how far you get!

(Usually you show your VI and we help you to improve it!)

Hi jyot,

dunno why you need interpolation functions here.

I just used a FOR loop to filter the points with "IF X<0 AND Y<0 THEN…"

Hi,

Actually, these are values on the x and (-y) axis taking as the marking value for the 4th quadrant.
