Plotly vertical X-Axis labels

It would appear that i can set the X-Axis labels to a 'vertical' orientation, but it doesnt seem to apply properly - am i missing something here?

I have also tried 'textangle' - not 100% certain on the difference here between text labels and ticks? either way, neither one seems to produce the right orientation.

It looks to me like i have set the correct parameter options. appreciate any help or insight!


tickangle is the correct way to rotate the text, but you seem to have "showticklabels" as false, which is hiding them
