Producing a graph

[star]

Hi all,

I was wondering how I could make a line graph in LabView. For example plotting numbers (83, 37,-27, 73,-21,-32.............).

The reason why I want to make a graph is because I am reading some values for a text file and then place the values on the graph. The x-axis is the number of items in the file and y-axis are the values. I made a code that reads from a text file and I have attached it below.

We don't know what your output string looks like, but essentially you need to convert your data to an array of numbers and pass that into your graph. Because your x-axis is just a count of data points you'll be better off using a waveform graph instead of an XY Graph. Look at the help for graphs for more info.

Now you can see what my output string looks like and i look at some waveform graph instead of an XY Graph and i still couldn't do it.

Thanks for your reply

Use Spreadsheet String to Array.vi and pass the output to your graph. If you need more help than that, http://www.urbandictionary.com/define.php?term=RTFM' rel='nofollow' target="_blank">RTFM.
