Here is a different way to do this. I wanted to plot a line segment
which was a least squares fit to a quadratic equation over N bars. I
wanted to be able to offset this plot to some arbitrary previous
position on the underlying price plot. And also be able to change the
number of bars in the fit (the length of the line segment).
I created an empty array by :
for ( i = 0; i < BarCount; i++ )
{
PlotArray = Null; // The Null value doesn't plot;
}
Then I filled just part of PlotArray with data I wanted to plot:
for ( i = 0; i < FastPers ; i++ )
{
Indx = (BarCount - (FastPers - i)) - Offs;
PlotArray[Indx] = ATERM + BTERM * X[i] + CTERM *X[i] * X[i] ;
}
Where:
Offs = the # of bars before today's bar
BarCount = total number of price bars present (system variable)
FastPers = the length of the quadratic line segment
Indx = pointer to the location in the array to put the data element.
Then I just plotted PlotArray with a regular Plot() statement
Maybe some variation of this can solve your problem.
