Hello All,
My question is regarding the attached plot. I would like to have multiple
transparent green bands running the length (yaxis) of the plot the width of
which is determined by the green lines at y=0 in the plot. Can you suggest a
way to do it?
Hi mnstn,
Transparency is only supported by some graphic devices. It may be
simpler to plot the values, use "rect" to draw green rectangles:
xylim<-par("usr")
rect(start1,xylim[3],stop2,xylim[4],col="green")
rect(start2,...
then redraw the lines over the rectangles using "lines".
Jim
