splitting text file to calculate with

[natabata]

Hi everyone,

I've just started learning with Labview in my new Job, pretty much learning by myself.

And my first "assignment" is to analyze data that looks like this(in a text file):

2013-04-09T08:13:30.000        324        Ihc        877.201554E-3
2013-04-09T08:13:30.000        324        Vhc        660.746743E-3
2013-04-09T08:15:00.000        262        Iho        614.054623E-3
2013-04-09T08:15:00.000        262        Vho        461.903473E-3
2013-04-09T08:16:30.000        277        Vhc        660.323204E-3
2013-04-09T08:16:30.000        277        Ihc        877.715994E-3

which will be calculated later, but right now i'm trying to get the data calculatable.

My first idea was to put it in an array, but i haven't managed to do it yet, and i'm thinking it might not be the best format to work with later.

I've attached the VI i've been working on, though it's clear to me why it won't work, and it probably isn't the best soloution.

Hello,

We need your sub-vi filelinenumberv2 to run the program.

If i have well understood :

you want to get the 877.201554E-3, 660.746743E-3, ... in a tab ?

sorry, i forgot that

but i think that my whole approach to the programm is wrong.

I need to have the data of each line in a cluster, so i can calculate the time(the timestamp + delay) and the Power (Ihc*Vhc or Iho*Vho)

out of that i will have to make a graph

Why don't you read from text file so you will get a 2D array but of strings

Index your 2D array into 1D arrays and typecast them to the correct type (time, dbl,...)

Keep you 1D array of timings

Bring other 1D arrays of data into a for loop with autoindexing ON

Do your calculations inside the forloop for every row

Bring the result of the calculations back out of the for loop.  => 1D array of calculations

=> 2 1D array => create graph

If that is what you're trying to achieve...
