Hi, I'm very,very new to maple, project due on monday so help needed urgently please! I have an array (as a result of dsolve) of the form below (obviously a lot longer) [a=0.001, b=123, c=345, d=565] [a=0.002, b=124, c=345, d=567] [a=0.003, b=125, c=456, d=765] I need to plot the first and third columns against each other so I used the op function to extract these columns arr := Array[1 .. 100]; for i to 100 do arr[i] := [op(1, ans(i)), op(3, ans(i))] end do However, this gives me [a=0.001, c=345] [a=0.002, c=345] [a=0.003, c=456] I can't plot this using pointplot, I would need further extraction to get just two columns of numbers. Can someone please tell me how to do this, or if its possible to plot it as it is. Thanks, Kate
