Trying to plot weekends only on the X axis.

Hello, I'm working with a data set that has three values per day on Friday and Saturday. I have 0:00, 8:00 and 16:00 for both days. I would like to plot 8 months worth of those two days. I can get it to work, but there are gaps from the end of Saturday to the beginning of the next Friday. Is there a way to still use the date and time, but eliminate the gaps that occur during the weekdays? Thank you

Not on a real time axis, no.

You would have to just plot the data against ordinal number and then label the ticks.

Such niceties would be nice as builtins but AFAIK there's no magic wand to wave.

If there were an option to not only have plot and friends ignore NaN/NaT data by not displaying it, but to collapse the underlying axis by removing such it would be a great boon.

I've made similar enhancment request in the (by now pretty distant) past, but none have been acted upon.

And now for the hard part, convincing a college professor it can't be done. :) Thanks for your time and answer.

I’m not certain if this is what you’re looking for, however the isweekend function may be worth considering.

I didn't say it can't be done; only that you have to create the appearance by subterfuge. :)

Plot the data against the ordinal number and label the ticks by the week or however is wanted.

Alternatively, you could potentially use the tiledlayout and put each week in the next tile. Unfortunately, again TMW is too clever by far for their own good and doesn't have a default layout in which the axes actually abut.
