[amibroker] Maintain Fixed Left Edge

["Ken Close" <ken45140@xxxxxxxxx>]

Is there any way to code a plot so that a specified bar is maintained at the
left edge of the screen as data is added at the right.
 
This applies to intraday plots.
 
I have some plots of relative performance normalized to the left edge of the
screen.  I set the Range to the 4:00 bar and the right most bar and expand
to fill the screen (Range command).
 
As data is added, the same fixed range shifts right, while I would prefer
the left edge bar to remain fixed, while the range expands.
 
Is there a way?
 
Thanks,
 
Ken
