Adding in major_label_orientation value makes chart blank
It turns out that this occurred because my x axis labels were too long. When I shortened the labels, the chart reappeared with the rotated labels. (Increasing the height of the figure might be another way to solve this issue.)
I'm creating a bar chart using Bokeh. My chart renders fine initially, but when I add in the following line (to rotate the X labels):
p.xaxis.major_label_orientation = 1.2
The chart becomes blank. Why is this occurring?
