How do I display different colors on the same connected series curve in SGPLOT?

[jibra]

I have time series data (by month) with two data elements that I wish to display on the same exact curve. I want to display an entirely connected curve with differnet colors assigned to certain portions of the curve. I use the "group=
function to distinguish between the different portions of the data. What I need is in the first figure I have attached (someone did this in excel). What I've been able to do is in the 2nd figure: you see my "group=" function causes each portion of the series to display independently. Has anyone ever done a series like this? Below is my code. Can it be adapted to have an entirely connected curve, or will I need to go another route?

data Attrs;

length Value $30 MarkerColor $20 LineColor $20;

ID = "BCFMT";

Value = "Dec 00-Feb 01"; MarkerColor = "Cyan"; linecolor= "cyan"; output;

Value = "Mar 01-Nov 01 (Recession)"; MarkerColor = "Blue"; linecolor= "Blue"; output;

Value = "Dec 01-Nov 07"; MarkerColor = "Maroon"; linecolor= "maroon"; output;

Value = "Dec 07-Jun 09 (Recession)"; MarkerColor = "Lime"; linecolor= "Lime"; output;

Value = "Jul 09-Aug 15"; MarkerColor = "Purple"; linecolor= "Purple"; output;

run;

You will have to provide an additional observation for the endpoint with the other series.

Since the data appears to be sorted by date you could use first. or last.processing to insert the additional obs with the other group setting.
