How do I get Waveform from a file........?

[Scopas, E.K]

Hi friends,

I'm still learning LabView programming, I've a file which contains
data (arterial blood pressure) and I want to sample...read lines from
a file. Secondly, I want to get waveform and extract features from it
e.g Max, Min, Mean.......how do I get that right? Maybe I've to
compute but how?

Thanks for your advice!

Here is a sample VI that will read in a text file and graph it and give the data for the file.just replace the read from speadsheet file if the file is not text.

Hope this helps. Also if you are just learning labview then you may want to get a book called labview for everyone second edition.

one very simple solution is to place
1. Read characters from file.vi
2. extract numbers.vi(in the examples/general/strings.llb)
3. string read from file vi
4. temperature graph


connect 1 to 2 and 3
connect 2 to 4
As you run the programme, you'll be asked to open a file and then view it on
the graph
