span color on graph sunset/dawn - mcgrim - Jun-13-2019 I am trying to color sections of this graph by dividing it into times from dawn to sunset and from sunset to dawn (next day). The graph looks (almost) exactly the way I want,but when I uncomment line 28 and 29 to span the colors throughout the times mentioned above, I get an almost empty graph with the hours overlapping each other to the left. How do I fix this problem? from astral import Astral import numpy as np import matplotlib.pyplot as plt import datetime import pytz import sys date_list = [date(2015, 5, 12), date(2015, 5, 13), date(2015, 5, 14)] data1 = range(47) data2 = [0, 0, 0, 3, 0, 0, 0, 0, 0, 0, 0, 0, 6, 1, 0, 1, 2, 4, 4, 0, 0, 0, 0, 0, 0, 0, 0, 10, 2, 0, 1, 0, 1, 0, 2, 0, 0, 1, 0, 1, 0, 1, 0, 0, 0, 0, 0] CEU_times1=datetime.datetime(2015, 5, 12, 3, 0, 5, 597773) CEU_times2=datetime.datetime(2015, 5, 12, 3, 0, 5, 597773) time_list=[CEU_times1 + datetime.timedelta(hours=i) for i in range(0,len(data2))] hours=[time_list[i].time() for i in range(0,len(data2),3)] city_name = 'Copenhagen' a = Astral() a.solar_depression = 'civil' city = a[city_name] sun1=city.sun(date=(CEU_times1), local=True) sun2=city.sun(date=(CEU_times2), local = True) #plt.axvspan(sun1['dawn'],sun1['sunset'],facecolor='green', alpha=3) ## the graph looks ok as long as these #plt.axvspan(sun1['sunset'], sun2['dawn'], facecolor='orange',alpha=3) ## two lines remain commented plt.bar(data1,data2, width=1, color='blue' ) plt.xticks(range(1, len(data2),3 ),hours, rotation=45) plt.gcf().autofmt_xdate() plt.twiny() plt.xticks((1,23,45), date_list, rotation=45) plt.show() |
