java - Creating a line graph with user input -

so having problem starting create line graph takes in values given user. have code have far (currently computes rate of growth part of assignment). need take values user inputs (bv1, ev_1, ev_2, ev_3, ev_4, , ev_5...), , utilize them plot points on line graph has amount of money on y-axis, , year on x-axis. labels of graph supposed utilize html formatting in java labels axes. know supposed utilize stuff superpaint g, , @override, not sure start (some illustration code help). help appreciated assignment due tomorrow!
