Description

Dear Pier,

I have repeated measures data from subjects across multiple conditions, that I'd like to show as raw data points + boxplots. I am using a combination of g.stat_boxplot and g.geom_jitter for this.

I would also like to connect data points across these conditions, to help visually identify subjects. A bit like this: 20200114_163336

The only such functionality I found in gramm was the 'geom',{'line', 'lines'} argument of g.stat_summary. However, that just connects the means/error bars, not the actual data points.

I could easily manually draw the lines myself in a for loop, however adding content to a gramm figure (with update) seems rather difficult/unstable.

Are you able to help? Thank you so much!

Tudor

Contributor guide

Research direction
Explore the existing geom jitter and stat boxplot implementations in gramm. Add a new option to draw lines between points belonging to the same subject across conditions. Use a grouping variable like 'subject' to connect points.
