I am a new user to LabView and this is my first project using it. The project requires me to read a massive spreadsheet from Excel into LabView and then allowing the user to do the following:
- Select which columns to plot against the first column
- Use a cursor to select a portion of the spreadsheet: the Vi will then average the selected data by column (in other words, if the user selects data across multiple columns, the program will average data in each column separately). Then write the averages to the csv file.
So far, I have the spreadsheet read into a table as strings (because the first row of the spreadsheet is words). I have spent a lot of time searching how to allow the user to select data on the table to perform operations on, but to no avail. I am hoping you guys could give me some insight on how to tackle this project.

Granted that I could do this very thing with two single-stack charts of 3 traces each. I could do that... However...
What I'd very much prefer is to have 1 chart with 2 stacks and 3 traces on each.
So my question is...Can I do that? And if so, how can I do that?
I'll tell you what this is for...
I have a test stand measuring pressure and flow. I want to show the current value for each in a separate, vertically stacked plot, with also the current max and min limits as dotted red lines. The settings are progressive steps, each with a different max and min for both those values. I want the operator to not have to think, only just look at the cart, and to know in an instant if it is performing amiss. Also an aid to troubleshooting. Save me a lot of headaches and interruptions down the road.

This Vi Calculate th Cp and Cpk values of a dbl array values.
It's quite usefull to do some statistical analysis of a process capability.
