[amibroker] Plotting when early bars are Empty

["Ken Close" <ken45140@xxxxxxxxx>]

I want to plot a series which begins at a recent day in the past.
 
If the bars visible on the screen is less than the total length of the
series, I can see my plot with a simple
 
Plot(series,"title",1,1);
 
If I scroll to the left or zoom out, the plot disappears.
 
So, I want something that allows the Plot to remain on the screen if the
first visible bar is earlier than the start of the series.
 
Plot(IIF(IsEmpty(Series),-1e10,Series),"title",1,1);
 
does not work nor do any variations I have tried.
 
Can someone please suggest how to make this happen.
 
Thanks for your suggestion.
 
Ken
