Bug Description
The raincloud plot (Spaghetti plot) in the Paired Samples T-Test always shows the same order of the two variables that you insert, irrespective of the order in which you insert the variables. E.g., when you insert the T1 variable first (left cell) and then the T2 variable second (right cell), the plot sometimes shows T1 on the right and T2 on the left.
When you switch the position of the two variables in the interface, the order in the raincloud plot stays the same (although in all other plots [bar plot, descriptive plot] the order changes).
Expected Behaviour
When the T1 variable is inserted first (into the left cell) and the T2 variable is inserted second (into the right cell), the raincloud plot should show T1 on the left and T2 on the right. When you insert T2 first (into the left cell) and T1 second (into the right cell), the raincloud plot should show T2 on the left and T1 on the right.
Steps to Reproduce
- open the attached file (T1T2simulation.csv)
- Chose Paired Samples T-Test
- Insert T1 first (left cell), then T2 (right cell).
- Activate Descriptive Plot, Bar Plot, and Raincloud plot.
- See how all three plots have the same direction (T1 < T2).
- Change the order of the variables (insert T2 first into the left cell, than T1 into the right cell)
- See how the raincloud plot does not change (T1 is still on the left), whereas both other plots change.
