Question: Plot in maple 12

I am trying to plot the following kind of sequence. I was expecting a curve for one set of [] inside plot command, but I am getting twin curve there. How can I get a single curve for one single parametric command there. Please reply asap.

plot([[(1.428571429*(r^2+.49-4*r*(r^2+.49-2*exp(-.1/r))/(2*r-.2*exp(-.1/r)/r^2)))*csc((1/3)*Pi), sqrt(16*r^2*(r^2+.49-2*exp(-.1/r))/(2*r-.2*exp(-.1/r)/r^2)^2+.49*cos((1/3)*Pi)^2-2.040816327*(r^2+.49-4*r*(r^2+.49-2*exp(-.1/r))/(2*r-.2*exp(-.1/r)/r^2))^2*cot((1/3)*Pi)^2), r = -10 .. 10], [(1.428571429*(r^2+.49-4*r*(r^2+.49-2*exp(-.1/r))/(2*r-.2*exp(-.1/r)/r^2)))*csc((1/3)*Pi), -sqrt(16*r^2*(r^2+.49-2*exp(-.1/r))/(2*r-.2*exp(-.1/r)/r^2)^2+.49*cos((1/3)*Pi)^2-2.040816327*(r^2+.49-4*r*(r^2+.49-2*exp(-.1/r))/(2*r-.2*exp(-.1/r)/r^2))^2*cot((1/3)*Pi)^2), r = -10 .. 10], [(5.*(r^2+0.4e-1-4*r*(r^2+0.4e-1-2*exp(-.2/r))/(2*r-.2*exp(-.2/r)/r^2)))*csc((1/3)*Pi), sqrt(16*r^2*(r^2+0.4e-1-2*exp(-.2/r))/(2*r-.2*exp(-.2/r)/r^2)^2+0.1e-1*cos((1/3)*Pi)^2-25.*(r^2+0.4e-1-4*r*(r^2+0.4e-1-2*exp(-.2/r))/(2*r-.2*exp(-.2/r)/r^2))^2*cot((1/3)*Pi)^2), r = -10 .. 10], [(5.*(r^2+0.4e-1-4*r*(r^2+0.4e-1-2*exp(-.2/r))/(2*r-.2*exp(-.2/r)/r^2)))*csc((1/3)*Pi), -sqrt(16*r^2*(r^2+0.4e-1-2*exp(-.2/r))/(2*r-.2*exp(-.2/r)/r^2)^2+0.1e-1*cos((1/3)*Pi)^2-25.*(r^2+0.4e-1-4*r*(r^2+0.4e-1-2*exp(-.2/r))/(2*r-.2*exp(-.2/r)/r^2))^2*cot((1/3)*Pi)^2), r = -10 .. 10]], -13 .. 5, -5 .. 5)
