I am using LabVIEW to measure the power of the laser. After measuring I plotted the power with time. I save these data. However, I could not get time in the saved file. How can I save time and power in a file?
I am sorry for asking this easy question.
We can't really debug pictures. (we can't see what is the other cases, we cannot see how the express VIs are configured, etc., we can't even see the toplevel loop (is there one or is this a subVI called from elsewhere?))
(Also, this seems to be a LabVIEW question. The problem is not with "instrument control" so I will move this post)
How can I save time and power in a file?
Right now you only save the "Power" value using this ExpressVI.
When you want to save a time value too then you need to save two signals (aka: an array of twi values!) with the same function!
So you could build an array from your time value and the corresponding "Power" value. (Or you may look into the properties of that ExpressVI to check if it allows to save time values automatically…)
