Hi people,
I have an spc control chart within my app. However for some reason the UCL, CL and LCL aren't showing on my graph.
A brief background:
This is an app for people entering measurement data into several numberboxes the average of which goes onto the graph. These numbers generally vary from 32.0 to 28.0
The UCL is at 30.6 the CL at 30 and LCL 29.4 However none of these values are showing on the graph.
Has anyone used this control and know why I am having a problem here?

My guess: you only input the UCL,CL,LCL once....
put them into a two dimensional array and feed this to the chart

Hi Henrik,
Thanks for the contribution however this didn't seem to work. It may be worth noting that I am not using a waveform chart and instead am using a "control chart" which is included in the SPC package.
If I could work out how I would include a picture of my current code however print screen seems to have stopped working (odd eh?)
Basically I have an array going into X and another array going into Y
There is a control which is generated by the control chart called control chart lines. I have hooked up my limits to this.
I can find very little documentation on this control and so have hit a bit of a wall
Vielen Dank für Ihre Zeit

Hi Rik,
I have just had a quick play with this contorl and have had no issues displaying the limits.
I have attached the VI below, have a play and see if this one works.

You my good sir are a legend. I had simply set this up wrong 🙂
Thanks so much!
The lack of resources online for these controls was quite disconcerting on this occasion.
