Using a comparison to run a case structure

[Jake Earp]

Hello,

I'm trying to write a simple program but I can't seem to figure out how to write it.

I have a dynamic series of data (about 16,000 values) running inside of a while loop.  

I want to add 180 to a value if that value drops below 30.

My idea was to:

  1.  Do a comparison:  "x < 30" to get a true or false value.

  2.  Send the Boolean along with Use a case structure to say if true

  2.  Then,if "true" x = x + 180, If "false" x = x (just passes straight through the case structure)

However, this always adds 180 to the value.

Please Help!!!!

Thanks, Jake

Thanks for that you're a legend.

However, whenever I change the dynamic data to an array like that, I loose my time values (sampling at 1000 hz).  That causes heaps of issues with other parts of my programme, is there any way around this?

You can retain the time values also. Since the sampling rate is 1kHz, the DBL array and the dt (1/1kHz) can be used to buid the waveform again.

Please refer the attached VI.
