我正在使用 matplotlib 創(chuàng)建圖表，這是我的代碼：fig = plt.figure(facecolor='#131722',dpi=155, figsize=(8, 4))ax1 = plt.subplot2grid((1,2), (0,0), facecolor='#131722')Colors = [['#0400ff', '#FF0000'], ['#09ff00', '#ff8c00']]for x in List: Index = List.index(x) rate_buy = [] total_buy = [] for y in x['data']['bids']: rate_buy.append(y[0]) total_buy.append(y[1]) rBuys = pd.DataFrame({'buy': rate_buy}) tBuys = pd.DataFrame({'total': total_buy}) ax1.plot(rBuys.buy, tBuys.total, color=Colors[Index][0], linewidth=0.5, alpha=0.8) ax1.fill_between(rBuys.buy, 0, tBuys.total, facecolor=Colors[Index][0], alpha=1)這是輸出：當(dāng)前輸出的問題是兩個區(qū)域的顏色正在“合并”：基本上藍(lán)線下方的區(qū)域應(yīng)該是藍(lán)色的，但它是綠色的。我怎樣才能將它設(shè)置為藍(lán)色，例如，就像我的例子一樣？示例List數(shù)據(jù)：[[9665, 0.07062500000000001], [9666, 0.943708], [9667, 5.683787000000001], [9668, 9.802289], [9669, 11.763305], [9670, 14.286004], [9671, 16.180122], [9672, 23.316723000000003], [9673, 30.915156000000003], [9674, 33.44226200000001], [9675, 36.14526200000001], [9676, 45.76024100000001], [9677, 51.85294700000001], [9678, 58.79529300000001], [9679, 59.05322900000001], [9680, 60.27704500000001], [9681, 60.743885000000006], [9682, 66.75103700000001], [9683, 71.86412600000001], [9684, 73.659636], [9685, 78.08502800000001], [9686, 78.19614200000001], [9687, 79.98396400000001], [9688, 90.55855800000002]]

您以錯誤的順序繪制并用新的繪制覆蓋了以前的繪制。
我試圖重新創(chuàng)建一個小示例，其中total_buy1> total_buy0，因此為了獲得所需的結(jié)果，您首先必須繪制total_buy1 然后total_buy0：
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
Colors = [['#0400ff', '#FF0000'],
['#09ff00', '#ff8c00']]
n = 100
rate_buy = np.linspace(0, 1000, 100)
total_buy0 = np.linspace(0, 300, n)[::-1] + np.random.normal(scale=10, size=n)
total_buy1 = np.linspace(0, 600, n)[::-1] + np.random.normal(scale=10, size=n)
ax.plot(rate_buy, total_buy1, color=Colors[1][1], linewidth=0.5, alpha=0.8)
ax.fill_between(rate_buy, 0, total_buy1, facecolor=Colors[1][0], alpha=1)
ax.plot(rate_buy, total_buy0, color=Colors[0][1], linewidth=0.5, alpha=0.8)
ax.fill_between(rate_buy, 0, total_buy0, facecolor=Colors[0][0], alpha=1)
我注意到您Colors[Index][0]用于兩個繪圖調(diào)用，因此線條和區(qū)域不會有不同的顏色。
