Drawing polygons on a time series

Hi everyone,

I've been trying to draw a time series with particular days highlighted by using the function gsn_add_polygon. Essentially I wish to draw the time series and highlight events by plotting vertical bars at different points in the time series.

A couple of issues have sprung up. Firstly, the bars do not span the y-axis (despite increasing the y coordinate of the polygon) and I'm not sure I understand why. Secondly, I can't change the colors of the polygons, they just remain black. I've attached both the code and the resulting plot. Does anyone has any ideas as to how I can fix this?
