如何在Pylot中仅显示时分坐标？

import pylotimport datetime# 时间数据（仅包含时分）x = [datetime.time(10, 59), datetime.time(14, 59), datetime.time(16, 59), ...]# 人为设置年月日为相同日期y_vals = [1, 2, 3, ...]dates = []for _ in range(len(x)):    dates.append(datetime.datetime(2023, 3, 8))# 创建图表fig = pylot.figure()fig.line(dates, y_vals, x_key=x)fig.show()
