Standardized plot in graph builder with spec limits

[#1]

When I drag and drop multiple coulumns with diffrent spec limits in the Y or X axis, JMP makes something like a standardized plot with point or boxplots.

It's a very nice feautre, but I could not find the documentation how the blue (spec) and gray (reference frame) lines are calculated.

Thanks!

I have not been able to replicate your findings.  What release are you using?

Hello Jim

Attached is a sample file with the script who produces the plot.

Thanks

What appears to be happening, is that when you drag in as many columns to the X drop area, Graph Builder is taking on the format of a Parallel plot, but without the connecting lines, just the default points.  So what you need to do is to look at the documentation for the definition of the graph.

THX, but I could't find something about this plot in the documentation.

If you are referring to the horizontal blue lines, they are not calculated.  They are taken directly from the USL, Target and LSL values in the column properties for the columns specified in the graph.  The gray vertical lines are also not calculated but are just reference points for each column.

The documentation can be found in

THX for the reply I read trough the doc and I played a bit with the spec and distribution. I think that the different scale of the spec limits is due to rounding of the individual axis.
