【问题描述】:
我有以下代码:
dates = pd.date_range('20130101', periods=6)
df = pd.DataFrame(np.random.randn(6, 6), index=dates, columns=["a","b","c","a_x","b_x","c_x"])
结果如下:
a b c a_x b_x c_x
2013-01-01 -0.871681 0.938965 -0.804039 0.329384 -1.211573 0.160477
2013-01-02 1.673895 2.017654 2.181771 0.336220 0.389709 0.246264
2013-01-03 -0.670211 -0.561792 -0.747824 -0.837123 0.129040 1.044153
2013-01-04 -0.571023 -0.430249 0.024393 1.017622 1.072909 0.816249
2013-01-05 0.074952 -0.119953 0.245248 2.658196 -1.525059 1.131054
2013-01-06 0.203816 0.379939 -0.162919 -0.674444 -0.650636 0.415143
我想生成简单的折线图——一共三个,每一个都绘制成对:
a and a_x, b and b_x and c and c_x
我知道如何生成图表,但是由于表格很大并且在列命名约定中具有相同的模式,我在想是否可以通过 for 循环来实现。例如,原始表会有column d and column d_x,还有column e and e_x 等。
