Well, a couple of things. AL_LEGEND requires a WINDOW
keyword, instead of an ADDCMD keyword to add the command
to the graphics window. But the biggest problem is that
you didn't set the Y range of your data on your first plot.
Since you are overploting your other data sets, the first
plot you create must have a range that is large enough
to accommodate all the rest of the data you want to put on
it. In this case, I also made the range large enough so I
could easily fit the legend onto the plot.
y1=[576.000,687.000,416.000,325.000,271.000]
y2=[665.000,702.000,527.000,493.000,433.000]
y3=[2333.00,2409.00,2168.00,1791.00,1583.00]
y4=[225.000,371.000,149.000,168.000,60.0000]
y5=[863.000,912.000,590.000,652.000,695.000]
y6=[546.000,539.000,336.000,322.000,275.000]
y7=[1431.00,1523.00,1001.00,914.000,892.000]
x=[-12,-8,0,5,10]

This works correctly. :-)
