With the ngspice gnuplot command, enable x/y contour plots for 2d Cider save file data. Usage: gnuplot <file> xycontour <expr>. xycontour is a new flag which is ignored if the plot data is not from 2d Cider. For contours, only a single plotarg <expr> is allowed. With <expr1> vs <expr2>, only <expr1> is plotted and <expr2> is ignored.
