Pls, I want to plot contour maps from XYZ data that is already saved in Microsoft Excel as delimited spreadsheet VI.csv file. How do I apply the solution given below by Altenbach Knight of NI?
Hey EngrSadiq, I would suggest making a new forum post and referencing this one with a link. This forum post is from 2013, so you're more likely to get responses if you create a new one!
Sorry, I was supposed to write earlier solution not solution below.
The data is separeted by comma, for all X and Y values. I have 3 rows and 169 columns. X ranges from -6 to 6 and Y also have the same range of -6 to 6. Attached is the copy of the whole data in Microsoft Excel as delimited spreadsheet VI.csv file. Thank you for your attention.
"Read from spreadsheet file" (or "read delimited spreadsheet" in newer LabVIEW version) will read your data into a 2D array. Use comma as delimiter.
Now you need to initialize a 2D array and replace elements with z data according to the xy indices.
2D arrays (or matrices) only have non-negative indices, so you need to offset the x and y to satisfy that constraint.
See how far you get. Let us know if you have more problems.
