Feature request: Plot multiple variables on same axes (repeated-measures data)

[shawkjon]

Hi Jamovi team,

Generally really impressed with the Plots tab - great work. For bar and box plots, might it be possible to add the ability to plot multiple variables on the same set of axes? Equivalent to e.g. SPSS's 'summaries of separate variables'. Without this option, I can find no straightforward way of plotting repeated-measures data (unless I'm missing something).

(I understand I could convert the data to long format, but that's not consistent with how Jamovi usually handles repeated-measures data so not really appropriate for teaching.)

And a related question - do you have a rough sense of when the next Solid relase will be, and whether it will include the Plots tab?

Thanks for all you do,
Sam

we might need a screenshot of the SPSS feature you're describing.

Say my dataset has multiple columns of reaction time data from the same task: RT_visual, RT_auditory, RT_AVcongruent, RT_AVincongruent...

As far as I can tell, there is currently no way of plotting a bar chart of these variables on the same set of axes.

The closest would be to run a RM-ANOVA and get an Estimated Marginal Means plot, but this does not benefit from all of the new editing tools in the Plots tab:

I only mentioned SPSS as one implementation of a solution. Before you generate a bar chart, you are prompted to indicate whether the data are "Summaries for groups of cases" (which is the current Jamovi implementation, appropriate for comparing between separate groups) or "Summaries of separate variables" (which is what I'm requesting, appropriate for comparing between multiple conditions in the same group of participants):

Does that make sense?
