我在一个图上绘制了 2 个线图，代表 2019 年和 2020 年船舶到达数据。对于每个折线图，y 轴代表船舶到达数量x 轴代表月份（三月、四月、五月等..）但是，我不确定如何让 y 轴值（船舶到达数量）显示在两个折线图上。有人知道怎么做吗？我的代码和折线图如下：# Trendline comparison of the total number of vessel arrivals in 2019 & 2020# Displaying all numbers to 0 decimal placespd.options.display.float_format = "{:,.0f}".formatVESSEL_ARRIVALS_2019 = MARITIME_DATASET_2019["VESSEL ARRIVAL NUMBERS"]VESSEL_ARRIVALS_2020 = MARITIME_DATASET_2020["VESSEL ARRIVAL NUMBERS"]# Displaying the plotted figurefig = plt.figure(figsize = (48, 20))plt.xticks(fontsize = 20)plt.yticks(fontsize = 20)plt.plot(LIST_OF_MONTHS, VESSEL_ARRIVALS_2019, color = "blue", linewidth = 3,  label = "2019 NUMBER OF VESSEL ARRIVALS")plt.plot(LIST_OF_MONTHS, VESSEL_ARRIVALS_2020, color = "red", linewidth = 3,  label = "2020 NUMBER OF VESSEL ARRIVALS")plt.title("TOTAL NUMBER OF VESSEL ARRIVALS 2020 ON 2019 COMPARISON", fontsize = 32)plt.legend(loc = "best", prop = {"size": 26})plt.show()
