 Hi Mathgroup,

 I think there is a little nonuniformitty in the syntax of Plot
 versus the syntax of ParametricPlot.
 Say I would like to show several curves, then
 Plot[{c1,c2,...,cn},{var,var0,var1}] works, but actually
 Plot[{{c1,c2,...,cn}},{var,var0,var1}] works. This is necessary to display
 solutions of say NDSolve via 

 Now the same problem with ParametricPlot. 
 Here the double List brackets do not work and one has to use:

 ParametricPlot[Evaluate[({{c1,d1},{c2,d2},...,{cn,dn}}/.sol)[[1]] ],

I think ParametricPlot should also work for a double bracketted first
argument. Is there anybody seeing a reason why this does not work already.
