我在一個圖上繪制了 2 個線圖，代表 2019 年和 2020 年船舶到達數據。對于每個折線圖，y 軸代表船舶到達數量x 軸代表月份（三月、四月、五月等..）但是，我不確定如何讓 y 軸值（船舶到達數量）顯示在兩個折線圖上。有人知道怎么做嗎？我的代碼和折線圖如下：# 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()
