How can I add a line to an imagec figure?

1 view (last 30 days)
Hi,
I use Matlab R2015b. I created an image in the following way:
imagesc(t,altitude,BS);
datetick('x', 'HH:MM');
colorbar;
where
t
is datenum. How can I add a vertical line to the figure when x is 17:30 i.e to the t(3952) data? I attached the figure.
Thank you for your help in advance!

It depends. The "figure" is the complete window. Do you add a line over the complete window? Or do you want to display the line in the axes? In this axes you display the contents of the matrix BS. Do you want to insert the line in this data matrix, or is it enough to draw a line on top of the displayed image?

Maybe (see my comment above):
line(t([3952, 3952]), altitude([1, end]))
