Dear All, I have a question about the dataset class. Suppose I have a variable "magnetization" in class dataset (see below). I prefer the data form as the following, X(1), y(1) X(2), y(2).. I want to know how I use the x of magnetization. I tried magnetization.x or magnetization.y, but it does not give me results. Many thanks for the reply. Sincerely, Huaiming class DataSet(ResultProperties): magnetization [x=[ 0. 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1. 1.2 1.4 1.6 1.8 2. 2.2 2.4 2.5] y=[0.000125981483652 +/- 0.000122322506977 0.00860528601563 +/- 0.000365690783567 0.0222620599739 +/- 0.00089047889358 0.0370211267606 +/- 0.000570927849528 0.048406793936 +/- 0.000429342486559 0.0584663763909 +/- 0.0004796634673 0.0728869134363 +/- 0.000659369158556 0.0893286949981 +/- 0.000587776900735 0.101889483066 +/- 0.000593519471563 0.1160502693 +/- 0.000825142408233 0.133805849632 +/- 0.00057575130612 0.165816585036 +/- 0.000469748080503 0.208087821355 +/- 0.000521162407847 0.258726150393 +/- 0.000553055778572 0.331226556639 +/- 0.000601625820527 0.434736729908 +/- 0.000675053120055 0.491099090239 +/- 0.0003387686197 0.499313131313 +/- 8.51581569713e-05 0.499728317659 +/- 5.31002968192e-05] props={'observable': 'Magnetization Density', 'local_S': 0.5, 'THERMALIZATION': 100.0, 'J': 1.0, 'SWEEPS': 100.0, 'L': 20.0, 'LATTICE': 'chain lattice', 'hdf5_p ath': '/simulation/results/Magnetization Density', 'xlabel': 'h', 'T': 0.08, 'yl abel': 'Magnetization Density', 'MODEL': 'spin', 'label': ''}]
