Re: [amibroker] PLOTSHAPES problem

["Gary A. Serkhoshian" <serkhoshian777@xxxxxxxxx>]

Hi,
 
You need to either do the following:
 
function fSelectDayAgo( n )
{
return IIf( DateNum()==LastValue(ValueWhen(DateNum()!=Ref(DateNum(),-1), DateNum(), n)), 1, 0);
}
arrSelectedDay = fSelectDayAgo(5);
PlotShapes( IIf( arrSelectedDay, shapeCircle, shapeNone ), colorGreen); // <--this doesn't plot anything
//while this does:
Plot( arrSelectedDay, "PP", colorRed, styleHistogram);
OR
 
Keep your code as is but change the plotshapes line:
 
PlotShapes( IIf( arrSelectedDay, shapeCircle, shapeNone ), colorGreen,0,0,0);
 
PlotShapes needs a ygraph reference.  When you have your plot on styleownscale with no min max range I assume it doesn't know where to plot.  so, you have to add the three extra fields to specify.
 
Hope this helps,
Gary
