Correct some lines in my project (VANET) and get out as result the curves with omnet ++.

I am looking for an expert in Omnet ++ to correct one function in my project and to leave curves with omnet ++ using @ signal / @ statistic. I need as results: curve1: axis y = number of cluster, axis x = velocity, legend1 = number of vehicles = 20, legend2 = number of vehicles = 30, legend3 = number of vehicles = 40. curve2: axis y = number of cluster, axis x = number of vehicles, Legend_1 = proposed clustering curve3: Axis y = ch duration (s), axis x = velocity [5,10,15 (m / s), ..] legend = proposed clustering curve4: axix y = PDR axis [64,68 .., 74], axis x= velocity Legend_1 = number of vehicles = 20 Legend_2 = number of vehicles = 30 For more details, i will share its on chat.
