Repeat legend with every page

Piet_Hoogkamer — Thu, 23 Nov 2017 09:19:43 GMT

When a graph is created (in Graph Builder) with multiple pages, using one of the variables as a page parameter, the legend is only shown for the first page.

How to repeat the legend for all pages?

Any suggestion much appreciated!

I am not aware of how to do that in Graph Builder. What type of graph are you building? If it is a scatter plot, you could use

Graph==>Overlay Plot

Specify your X and Y variables, and then the Page variable, put in the By selection box.

Once it is run, you can hold down the CNTL key and right mouse click, and select Row Legend. The select your color variable, and the legend will be shown for each graph.

Thanks Jim, this is helpful!

Being addicted to the graph builder, I rarely look at the other options, so lesson learned (at least for the scatter plot).

However, I still would like to see the same for the graph builder, as there are clearly differences in options.

Using 'Overlay plot' and 'Graph Builder', with my data looks as below.

The graph builder plots are for me much nicer, with a more clear relation of the points to the sample class (with some optional jitter).

Best, Piet.

I agree with your statement, and I suggest that you send an enhancement request to

Hi @Piet_Hoogkamer,

The trick here is to use the Dialog option in Graph Builder, then use the By role for your Label column, rather than Page. Graph Builder will then repeat the legend for each graph.

I hope this helps!

Hi Julian,

Many thanks!

This indeed solves this problem (and open a door to new options!).

Best regards,

Piet

Hi Julian,

Three years later, we have JMP 15 and this solution doesnt work. It creates for ech "by" category an extra page. Do you know, how it works with JMP 15.

Hi @lena

Can you explain in more detail what functionality you are missing in JMP 15 that you had before? I tried this on my side and I can produce the same separate graphs with separate legends. There is the "Page" role that you won't want to use, but as far as I can tell, "By" works as it did before. I'm sure I'm missing something, so let me know what it is and we can figure out how to do it in JMP 15!

Hi Julian

i used the dialog builder wrong. thats why it didnt work with the labels. Now it works. Thanks for fast reply.

I'm having the same problem in JMP 15. I use graph builder and create multiple graphs by dropping a variable in the "Page" box; but the legend only shows up on the first graph. How were you able to resolve this?

Re: Repeat legend with every page

Piet_Hoogkamer — Fri, 19 Jun 2020 18:53:13 GMT

Please have a look at the solution posted by Julian: start in graph builder with dialog and then use the by option instead of the page option for your grouping variable.

Hello,

The trick is to use the DIALOG option to start making a graph.
When you open the graph builder, you will see this option.
Rather than using the PAGE option for your grouping variable, use the BY option instead.
Please make sure that in the DIALOG box the legend variable is selected for OVERLAY or COLOR.

Thank you. I had never used the dialog option before to start a graph.

This is beautiful. However, I have two issues.

1. The x-axis categories for my Pages (using the "By" command) are not always the same, as I would like them to be. Specifically, I'm using "Year Quarter" as ordinal x-axis. So if one page does not have data in 2022-Q4, but another page has no data in 2022-Q2 and 2023-Q1, the axes from page to page are not the same. I can work around this by entering zero as my continuous data for a given category, but that's NVA. Can we force the x-axes to be the same on every page (it seems this is the default when "Page" is used instead of "By").

2. If a legend category is not used on a page, it does not appear in the legend. Again, I'd like the legend on all pages to be identical. "By" is certainly superior to "Page" in this regard, but it would be even better if the legends could be forced to be identical. In my case, my y-axis continuous data are lost hours of production for a manufactuing process. I'm using a stacked bar. My categories for the legend ("Overlay") are loss reasons (e.g. "Not following procedure", "Corrosion", "Rotating equipment failure", "Raw material shortage"). The advantage to having the legend identical, even if a particular category is not present, is that it reinforces to the audience that in fact this cause is ZERO on this Page, whereas it is non-ZERO on another page.

Hm, how bad that the cool features are evenly split between Page and By - and not grouped ...

For 1, I also used some dummy rows to span the grid (and more severe: Group X/Y grid of FrameBoxes) similarly in all By-Plots.

For2, it helps to define Value Colors for the Overlay Column. Then all By-Graphs will automatically share the same color coding - and vice versa, the audience can easily get from the legend that one cause was ZERO on the page.
If you want to have exactly the same legend, you could also add some dummy rows to fill the legends.

Due to the dummy row, age=17 (with just "M") gets the same legend as age=12:

Names Default to Here(1);
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << << Select Rows( [38] ) << Delete Rows;

dt << Add Rows( {age = 17, sex = "F"} ); // dummy entry to get the legends aligned

Graph Builder(
	Show Control Panel( 0 ),
	Variables( X( :weight ), Y( :height ), Overlay( :sex ) ),
	Elements( Points( X, Y, Legend( 1 ) ), Smoother( X, Y, Legend( 2 ) ) ),
	By( :age ),
	Where (:age ==12| :age==17)
);
