Hi Yeping,
It's possible to create a such a label, but unfortunately it's a bit
complicated. The following script places a label with 2500 states in the upper
right corner of the display area.
# create a discrete multi-state object with one labeled atom per state
pseudoatom tmp, label=pending
python
for i in range(2500):
cmd.label("tmp", "'{} ps'".format(i * 80))
cmd.create('timestaple', 'tmp', 1, i + 1, discrete=1)
python end
delete tmp
# anchor the label in the upper right corner
set label_screen_point, [1, 1, 0], timestaple
set label_relative_mode, 1, timestaple
# align the label to the bottom left of the anchor
set label_position, [-1, -1, 0], timestaple
Those label settings are documented here:

Hope that helps.
Cheers,
Thomas
