I have many overlapping data points and I wonder if it is possible to jitter them only in one direction, on the x axis where I have categorical variables. I was trying various commands in the ggraph but it did not work.
Just figured this out:
- Create scatterplot as normal except don't click OK at bottom of the dialog box, click Paste.
- This will create a list of text commands to make the plot in the syntax window.
- Near the end of the list is a command point(...). Change that to point.dodge(...)
- Highlight everything in the syntax window and click the green arrow to run.
I don't use SPSS so not sure if there is a command for this. But you can force your data to jitter by: 1) looking at the number of observations with the same value, and 2) adding or subtracting a small delta value to the points, prior to using a graphical procedure/command.
Alternatively, paste the graph into Powerpoint, ungroup the image and then do what you need to - this has worked for me in the past for graphs produced in SPSS. Just take care not to jiggle your data so that you change the results!
