How can I save multiple data coming in from my data string

[Big G]

I am a newbie at labview. I have a scale connected to my RS 232 and made a VI to display the changing scale. I am trying to save the multiple changes as my weight varies but have been only able to save the last value. Is there a simple way to save all the values I see in my VI to a file for later plotting? I have done one before using indexing but the case this time is that I am receiving a character string and not a numeric array. Any examples or advice would be great!!! Thanks

Hi Gerald,

What you need to do is write to a file continuously, i.e. after each point you collect.  You can do so by opening a new/existing file, write to it inside your while loop, and close it once you are done collecting and writing data points, i.e. outside the loop.

I believe the following example is a good demonstration of that operation.

Best of luck,

If you don't want to continuously save the data you need to accumulate it into some buffer. (e.g. building an array in a shift register).

You could even simply use a waveform chart, then save the history data as desired.

Thanks for the help guys, I did end up using the waveform chart method......Gerald
