我一直在使用 Matplotlib 將不同的數(shù)據(jù)集繪制到同一個圖中（比如比較線圖），每個數(shù)據(jù)集都有不同的 x 軸和 y 軸值。例如數(shù)據(jù)集看起來像：x = [['12.63', '13.50', '14.15', '15.18', '16.04', '17.28', '18.56', '19.70', '20.90', '22.21', '23.25', '24.13'], ['13.39', '14.10', '15.05', '16.20', '17.55', '18.43', '19.75', '21.29', '22.78', '24.00', '24.85', '24.81'], ['13.02', '13.86', '14.82', '15.80', '16.90', '17.99', '19.24', '20.79', '22.30', '23.43', '24.38', '24.68']]y = [['-15.09', '-15.19', '-15.23', '-15.32', '-15.07', '-15.11', '-15.04', '-15.08', '-14.97', '-14.98', '-14.89', '-15.12'], ['-15.91', '-15.89', '-15.90', '-15.96', '-15.55', '-15.58', '-15.51', '-15.48', '-15.42', '-15.40', '-15.85', '-16.64'], ['-15.71', '-15.75', '-15.83', '-15.83', '-15.54', '-15.55', '-15.53', '-15.47', '-15.41', '-15.33', '-15.43', '-15.97']]我如何制作如下例所示的比較圖表（來自谷歌的參考）

首先，您的數(shù)據(jù)是字符串。您應(yīng)該將它們轉(zhuǎn)換為浮點數(shù)。
然后，最簡單的方法是多次調(diào)用 plot 函數(shù)，每行一次：
x = [['12.63', '13.50', '14.15', '15.18', '16.04', '17.28', '18.56', '19.70',
'20.90', '22.21', '23.25', '24.13'],
['13.39', '14.10', '15.05', '16.20', '17.55', '18.43', '19.75', '21.29',
'22.78', '24.00', '24.85', '24.81'],
['13.02', '13.86', '14.82', '15.80', '16.90', '17.99', '19.24', '20.79',
'22.30', '23.43', '24.38', '24.68']]
y = [['-15.09', '-15.19', '-15.23', '-15.32', '-15.07', '-15.11', '-15.04',
'-15.08', '-14.97', '-14.98', '-14.89', '-15.12'],
['-15.91', '-15.89', '-15.90', '-15.96', '-15.55', '-15.58', '-15.51',
'-15.48', '-15.42', '-15.40', '-15.85', '-16.64'],
['-15.71', '-15.75', '-15.83', '-15.83', '-15.54', '-15.55', '-15.53',
'-15.47', '-15.41', '-15.33', '-15.43', '-15.97']]
fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
ax.plot([float(n) for n in x[0]], [float(n) for n in y[0]], color='tab:blue')
ax.plot([float(n) for n in x[1]], [float(n) for n in y[1]], color='tab:orange')
ax.plot([float(n) for n in x[2]], [float(n) for n in y[2]], color='tab:red')
plt.show()
