I want to record the primal bound along with the time spent, in order to plot the figure.

  Hi Liu,

  You can parse and plot the log using gurobi-logtools.

  import gurobi_logtools as glt
  
  results = glt.parse("yourlog.log")
  glt.plot(results.progress("nodelog"))

  See the full example in the gurobi-logtools.ipynb

  Alternatively, you can achieve this manually using callbacks.
  Please see:  Tutorial: Customization Through Callbacks.

  Cheers, 
  David
