plot problem

[Zhang-Wen-Jun]

I think in the file plot_utils.py, the variable 'all_curves' used in the outside of the loop only saves the last algorithm's results, in this way, when we add several algorithms in the config, the plot figure result will cut the other algorithms' trend by following the last one's scope.

max_acc = np.max([max_acc, np.max(all_curves) ]) + 4e-2
