Don,
I am sure you read the help file for PlotShapes() function and the offset
feature.
SYNTAX PlotShapes( shape, color, layer = 0, yposition = graph0,
offset = -12 );
RETURNS NOTHING
FUNCTION Plots arrows and other shapes on any chart pane.
Parameters:
a.. shape defines type of the symbol. when shape is zero nothing is
plotted values other than zero cause plotting various pre-defined shapes.
Odd values plot shape BELOW indicator, even values plot shape ABOVE
indicator.
b.. color defines color of shape
c.. layer defines layer number on which shapes are plotted
d.. yposition defines Y-position where shapes are plotted (by
default they are plotted 'around' graph0 (first indicator) line)
e.. offset - (or distance) parameter (by default -12 ), Offset is
expressed in SCREEN pixels. Negative offsets shift symbols down, positive
offsets shift symbol up. To place the shape exactly at ypostion, specify 0
as offset
