Sequential analysis plot error
Hi, I ran several Bayesian t-tests but one of them did not produce a sequential analysis plot - instead it gave an empty figure saying 'legend is of length 0'. I've attached a screenshot.
I don't seem to have any missing data or odd types of data in those columns, so am not sure why it is just that one figure that is messed up when all the other variables produce it fine.
Does anyone know why this would happen and how to fix it? thanks
