Hello everyone I am having some trouble trying to make a VI for relative humidity. I've already correctly scaled the unit within NI MAX and its displaying the correct output in RH% already as opposed to mA.
I ultimately want to have the VI show/do:
- Current RH% gauge (working)
- Current time as X-axis but is scrollable (not sure if scrolling works)
- Current RH as Y-axis (not working)
- Export information to excel document with column for time and rh% (not even coded...)
I was able to change the "absolute time" to show correctly as opposed to the default which was some strange 1904 year. I got this to populate on the X-axis for the wave form chart but I cannot get the Y axis to work for humidity. I'd also like to be able to scroll right to left to see previous time values for RH on that chart but I haven't really gotten that far either.
Lastly I'd like to export this data to an excel file with headers/columns for time and RH. Since it doesn't necessarily have to be real-time, I'd also like to make the "data intervals" to be every 10 minutes if possible.
I've never really used labVIEW before so I'm a bit confused as to what to do and I would greatly appreciate any help. Please forgive the very noobish VI setup....The VI and screenshot of blockdiagram is attached
THANK YOU!
