What release of SAS do you have? This is very easy with SGPLOT. Just put the categories in the order you want in the data, and use the option DISCRETEORDER=DATA on the YAXIS statement. Categories are shown top to bottom in data order. You can use REVERSE to flip it. Using program below, note "Hybrid" is last because it is last in the data.
proc sgplot data=sashelp.cars;
