[Feature Request]: Full matrix display for scatterplot matrices in Descriptives-Basic plots-Corrrelation plots
Description
Give the option of plotting the full matrix, instead of just the upper triangle piece
Purpose
Better visualization of relationships (may look different when axes are swapped) and ease of finding the pairwise plot you're looking for
Use-case
Analyzing or teaching about variables interrelationships
Is your feature request related to a problem?
Student's difficulties in navigating upper triangular format. Also compatibility with similar charts from, say, Minitab and others.
Is your feature request related to a JASP module?
Descriptives
Describe the solution you would like
Having the option of choosing either full or upper diagonal matrix on Correlation plots
Describe alternatives that you have considered

@bensagalovsky thx for the request. I can understand the desire to have similar charts between apps (minitab etc). So maybe we could include this option.
Regarding "ease of finding the pairwise plot you're looking for" - have you tried the pairwise plot options under "customizable plots" and "regression => correlation"?

Hello @tomtomme , and thank you very much for your prompt attention and thorough response, and please excuse my delay in responding on my part.
As per your question: Regarding "ease of finding the pairwise plot you're looking for" - have you tried the pairwise plot options under "customizable plots" and "regression => correlation"?
The interesting thing is that these all show the same, upper triangular part of the matrix plot. For instance, the first variable appears as Y and the second as X, but never the first as X and the second as Y - I hope this explanation makes sense.
I find it useful to look at those graphs both ways (even though they're specular reflections), as some of them stand out more than their reflection.
Technically, for Descriptives>Descriptive Statistics>Customizable Plots>Scatter plots, if you Add regression line and Show confidence intervals, those would be different for each chart and its reflection (X<->Y), as would all the regression lines on the other graphs. Hope this makes sense as well. But it is more the visual than the technical aspect that motivates this request. Thanks!
@bensagalovsky You are obviously correct, that switching x and y gives different regression lines, so the scatterplot is not identical in that sense. If I wanted to currently get both parts (the full matrix display of scatterplots) as you suggest, then I would got to:
- Regression => Correlation => switch display pairwise off & switch on Scatter plots
- put in the two variables
- duplicate the analysis
- switch the order of the variables via drag and drop (this creates the plots you want to see)
Does this suffice? Otherwise we indeed would need an option to switch on the full matrix
Hi all,
I think it's definitely feasible to include the inverted scatterplots below the diagonal in the Descriptives module. I experienced similar confusion in my own teaching, and having both versions in that matrix plot could perhaps help to demonstrate the impact of assigning variables to the x/y axes in a single figure.
In the Regression - Correlation module this is a bit trickier, because we use that space to display the correlation coefficients and confidence intervals.
Cheers Johnny
Thank you @JohnnyDoorn for putting some thought into this request, and for sharing your thoughts about using these plots when teaching.
