I believe that this is the interface for the step plot with the old
plotting code and no longer works.. The "L" format should be removed
from the plot help text. For the above try

stairs(0:9,1:10)

Which is the matlab way of doing this. It doesn't look like the stair
plot handles the properties yet, and this should be fixed, with the
attached patch. After applying this patch try

stairs(0:9,1:10,'1');
hold on
stairs(0:9,2:11,'2');

for something like the above.
