I have a couple of questions about the graph builder in JMP 8. I'm a fairly new user of both JMP and this forum, so I apologise if this is the wrong place for it!

I am trying to use the graph builder to do wafer mapping (Fit X by Y) plots. I have two columns with Die X and Die Y positions, a column with a failure bin category (a nominal data set) and a column with a leakage current (a continuous data set). The data is also split into 25 wafers per lot.

I am using different colours to identify individual failure bins, or the leakage current (by grouping the continuous data).

My first question is: when I'm plotting the continuous data (which I put into the overlay area), I can only five different groupings (i.e. colours) in the legend, which are not evenly spaced. Is it possible to control (using JSL ideally) how many levels there are and how the levels are split? This is possible using the contour plot platform and I am currently using that as a stopgap, but the contour plot isn't ideal for this kind of application.

Secondly, when I group by wafer, it defaults to a maximum of four plots horizontally per row (which gives 7 rows with only 1 graph on the last row). Can I tell JMP to plot five graphs per row (which would give me a much more appealing 5 x 5 layout)?

I hope these questions make sense and that someone has some ideas!

Many thanks,

Matthew.

When you use a continuous variable for grouping, the ranges are determined by quantiles so that about the same number of observations are in each group. When I want more control, I make a new categorical column with just the ranges I want and use that as the grouping/overlay column.

For your other question, we don't have a way to customize the wrapping graphs per row. I will see if 8.0.1 can at least make a better choice for cases like 25.

thanks for the note. If it could be included in 8.0.1 (and the 64-bit Linux version of JMP 8, which we will be moving to when it's released) that would be great!

Matthew.

I am looking at a trial version; and it doesn't look like the ranges are determined by quintiles.

Namely: I have a variable with min=.003; median=.02; 99.5'th quartile=.086; max.=2.4 -- and when I try to use it to wrap the plots (of two other variables) by I am getting three empty plots with ranges [2.4 - 2.4] each.

Is there any way to make it work (other than manually creating rank or quintile variables)?

Thanks!

I normally do alot of Copying out of JMP directly to an email(Microsoft Outlook). The Graph builder is quick and I prefer using it but without this functionality its unusable to me.

Thanks,

Rod

No way I know of to avoid the loss of indentation.

EDIT: I also added spaces in [ i ] -- otherwise it seemed to still trigger italics.
