Calculating a table of electron transport properties using Magboltz

Garfield++

I have generated a N2 gas file,and now I want to plot the electron transport properties using Magboltz, the code is in the below, but there is no plot at all.

MediumMagboltz gas;
  gas.LoadGasFile("N2.gas")
  gas.PrintGas();
  ViewMedium view;
  view.SetMedium(&gas);
  view.PlotElectronVelocity('e');

I have solved the problem and get the electron velocity plot, I think the reason maybe I should rebuild a new example instead of just modify the code in the gem.c then cmake …
