[amibroker] Help with Linearray

["Herbert Elstein" <herty@xxxxxxxxxxxx>]

Hi,
What looked like a simple code got me trying all sorts of ingenious 
but ineffective codes.

I'm trying to draw lines from a pivot area top and bottom on the 
latest Monday,(I'll show only the top line) but only extending to 
the right on subsequent days.

The following code is correct but the line extends across the whole 
chart, which is not what I want.

// Calculate the pivot range:
PivotBand = abs(Avg - (H+L)/2);
VaH = Avg + PivotBand;
VaL = Avg - PivotBand;
Lu=LastValue(ValueWhen((DayOfWeek()==1),VaH));
Plot(Lu,"",colorBlack,styleLine);

So I tried the following code but it still displays the line across the whole chart. So where am I off course? Or is this approach not feasible?


yu0=Lu;

yu1=Lu;

xu0=LastValue(ValueWhen(Lu,BarIndex(),1)); 

xu1=xu0 + 1;

pu=LineArray(xu0,yu0,xu1,yu1,2); 

Plot(Lu,"",colorBlack,styleLine);

Thanks for the tackle,
Herbert
