Line connecting points through different groups in Graph Builder

ad_ — Fri, 15 Jul 2016 14:53:11 GMT

Hi all,

I am having some trouble with my scatter plot on Graph builder. I am looking at a variable evolving with time, with several times on different days. I study that variable for three different treatments applied. I am just at the step where I want an overview of my data, so I'm looking essentially at the trends. In one treatment there are different individuals (identified with different colors).

I have plotted the values for different times through the day, with treatment as Y grouping and date as X grouping. What I would like to add is a line connecting not only the points from a same day/same treatment, but across date, to have an evolution in time (eg. Individual A has been measured one time on Monday, three times on Tuesday, two time on Wednesday, I'd like a line linking all these points).
It seems extremely easy, but I have spend so much time trying to group differently the variables, to look for preferences and options ! I am convinced there is an easy way to do that, yet I can't find it. Any idea would be a great help !

Many thanks for your advices,

If "Individual" is a separate column, you might get what you want by specifying "Individual" as the "Overlay" variable

Hi A.

Could you provide a screenshot of your Graph Builder contents so our helpful JMP experts can better assist you?

(you can rename variables, pixelate or blur the sensitive areas to anonymize, if needed)

Like what Jim Nelson said, the Overlay Grouping Variable drop zone (fig. 1, label # 1) will help you see the trend you want - by factors (based on your setup).

However, you mentioned that:

"...with treatment as Y grouping and date as X grouping." (fig. 1, label # 2).

If you put the date in the Group X drop zone (fig. 1, label # 2), you won't be able to see a trend or use the Line & Overlay option (fig. 3).

Using the Group X drop zone, the mini graphs will be separated and will behave independently of each other - like the scatterplot matrix or R Studio's ggplot facet.

To see the trend (connected lines across dates), you need to put the dates in the X drop zone (fig. 2).

* This is based on my limited knowledge of JMP 12. Please correct if needed.

Hope this helps.

fig. 2 (Overlay & Line option enabled to show trends - because date is in X drop zone)

fig. 3 (Trend will not show because Line option is disabled when date is entered in the Group X drop zone)

Hi all,

Many thanks for your examples;

Indeed with 'date' as grouping variable, every date is like an independent graph and that was my question I guess, so it is not possible to link different graphs together. But for what I need to do, adding 'date' with the different times on the X axis work as well, as long as I want to keep a chronological order.

Thanks again for your help !
