Grand mean - Round value on chart

[#1]

Hey JMP Commuity!

I'm trying to find a way to get the grand mean that's shown on a variability chart to show to either a whole number or to one decimal place. 

I've tried formatting column properties as I've read this is related to the displayed mean (tried multiple options but mainly precision) but no luck!

I've also read about the rounding function, but my understanding is this only works when you specify the number - is there a way to do this for a grand mean? I'm also not very savvy with the code so I'm not entirely sure where in my script this would go.

Any help would be greatly appreciated!

Thanks, 

Anna

If I remember correctly that Avg text in variability charts has been built in fairly annoying way and manipulating it isn't that simple. It is in its own framebox and is using CustomStreamSeg which isn't documented segment.

You can slightly modify the rounding using Fixed Dec formatting (no idea how JMP determines what to show in the Avg)

Best:

Fixed Dec

So if this is enough I would try it first.
