Mosaic Plots Question

Steven_Moore — Tue, 26 Aug 2014 16:55:24 GMT

Is it possible to condtruct Mosaic Plots with equal widths for the X factors similar to what can be done with Box Plots?

Sorry for the typo: "Is it possible to construct...."

In a Mosaic Plot, the proportions on the x-axis represent the number of observations for each level of the X-variable. This is for explanatory value afforded by the plot to explain an additional dimension to the visualized graphic.

An alternative view that I like using graph builder is a heat map with the frequency color scale. This view uses equal real estate for the x-axis.

LouV, Yes, I understand why the columns are not the same width. Boxplots can do the same thing, but you can have the boxes the same width if desired. I was hoping this ability could be envoked for mosaic plots as well.

Thanks for your response.

smoore2,

Have you shared your desire with support@jmp.com so that it can be considered in the future?

I will do that. Thanks!

Hi Smoore2,

Using graph builder you can create a mosaic plot with either proportionally sized or equally sized x categories.

If you use your X variable in the X drop zone, you will produce the typical mosaic plot with proportionally sized categories on the X

But, if you use your X variable in the "Group X" drop zone at the top, JMP will size the categories equally.

If you right click the category labels on the top, then select "X Group Edge" you can move the labels to the bottom (to most closely resemble the original mosaic plot).

I hope this helps!

Julian

This is a good solution for the simple situation as discussed.

If I want to generate a plot combining several variables, then I usually must put one variable in the X drop zone and then the proportional sizing is no longer available for this variable.

By the way, I usually am not free to select which variable is dropped in the x-zone because of the fixed priorization of x and Group x drop zones in the set-up of the plot.

Hi @winfriedkoch0,

With more than two variables things do get a little more complicated. One thing you can do is to use more than one variable in the "Group X" and "Group Y" drop zones by dropping another variable in the nesting zone on the left or right (see gif below) to retain fixed width sizing. Another option (which might be useful if you have a large number of variables and don't want the hierarchical heading) would be to make a new variable that's a concatenation of several other categorical variables and then use that composite variable as the Group X.

Hope this helps!
