Hi friends.I am practicing tutorial and I faced one code for doing one plot with all data like this: #load the binning analysis for the absolute value of the magnetization binning = pyalps.loadBinningAnalysis(pyalps.getResultFiles(prefix='param'),'|Magnetization|') binning = pyalps.flatten(binning) #make one plot with all data for dataset in binning: dataset.props['label'] = 'L='+str(dataset.props['L']) plt.figure() plt.xlabel('binning level') plt.ylabel('Error of |Magnetization|') pyalps.plot.plot(binning) plt.legend() plt.show() Now I have 2 question: 1. I can not understand what is the meaning of : " dataset.props['label'] = 'L='+str(dataset.props['L'])",what is its meaning? 2. And also if I wanna plot energy versus temperature , which part of the above code must be changed ? thanks alot for your help
