Please add more cases to test the behavior when:

• xAxis is time
• xAxis is category
• yAxis is time
• yAxis is category
• encode 0 as y
• encode 0 as x
• data uses daval
• data uses datay

And it would be better if you also test if this change works for #20319 (include boxplot on time axis) as well.
