同时绘制两个图形时出现了一些麻烦,没有在一个图中显示。但是根据文档,我编写了代码,只有图1所示。我想也许我失去了一些重要的东西。有人可以帮我弄清楚吗?谢谢。(代码中使用的* tlist_first *是数据列表。)
plt.figure(1)
plt.hist(tlist_first, bins=2000000, normed = True, histtype ="step", cumulative = True, color = 'g',label = 'first answer')
plt.ylabel('Percentage of answered questions')
plt.xlabel('Minutes elapsed after questions are posted')
plt.axvline(x = 30, ymin = 0, ymax = 1, color = 'r', linestyle = '--', label = '30 min')
plt.axvline(x = 60, ymin = 0, ymax = 1, color = 'c', linestyle = '--', label = '1 hour')
plt.legend()
plt.xlim(0,120)
plt.ylim(0,1)
plt.show()
plt.close() ### not working either with this line or without it
plt.figure(2)
plt.hist(tlist_first, bins=2000000, normed = True, histtype ="step", cumulative = True, color = 'g',label = 'first answer')
plt.ylabel('Percentage of answered questions')
plt.xlabel('Minutes elapsed after questions are posted')
plt.axvline(x = 240, ymin = 0, ymax = 1, color = 'r', linestyle = '--', label = '30 min')
plt.axvline(x = 1440, ymin = 0, ymax = 1, color = 'c', linestyle = '--', label = '1 hour')
plt.legend(loc= 4)
plt.xlim(0,2640)
plt.ylim(0,1)
plt.show()
