add line in a datetime plot

Hello I have a figure with datetime in x- axis. I want to plot a vertical line like the one you see in attached picture but through code (and not manually through insert-->line). I tried:

plot([92594 92594],get(gca,'ylim'),'linewidth',1.2,'LineStyle','--','color',[0,0.8,0])

where 92594 is the exact point but i receive an error "Values plotted against x-axis must be datetime values. To create datetime values, use the DATETIME function."

Any ideas how to do this?

First, plot some duration data.

y = (0:59);
x = duration(0, y, 1);
plot(x, y);

Now add a line at a specific value. Note that since I plotted with duration data on the X axis, when creating an xline I must create it at a duration value. If I tried something like xline(15) that wouldn't work.

xline(duration(0, 15, 0))

It was introduced in 2018b so if you’re using a prior release it won’t work.
