Custom X-Axis gridmark labels

Is it possible to create custom axis labels?

For instance, I have a bunch of traces where x is just an array of DateTimes.

However, I’d like to have the x-axis gridmark labels just show the day of week (M, T, W, Th, F) etc, while still preserving the time info.

Thank you in advance.

Here’s how:

using xaxis.tickvals and xaxis.tickvals

Thank you!

(I had checked the plotly.js cheat sheet and didn’t see anything about tickvals there.)

Is there another resource you go to that displays all the options for every argument?

Thanks again!
