如何使用matplotlib绘制酒吧时间线? [英] How to draw a bar timeline with matplotlib?

问题描述

我有以下数据类型:

开始结束事件2003 2007年赛事11991 2016 活动二2008 2016年赛事31986 2015 事件 42013 2013赛事51994 1999 事件 62002 2002年赛事7

我的目标是制定这些事件的时间表，即绘制从日期1到日期2的一系列不同的直线和水平条，上面带有事件的名称.

我目前正在使用matplotlib中的 barh 函数来试试运气，但是我想知道python中是否已经有一个现成的模块，可以与matplotlib和pandas很好地集成吗?

解决方案

我认为这里不需要特殊功能.使用 plt.barh 直接为您提供所需的情节.

 将matplotlib.pyplot导入为plt将numpy导入为npbegin = np.array([2003,1991,2008,1986,2013,1994,2002])end = np.array([2007,2016,2016,2015,2013,1999,2002])event = ["Event {}".format(i)for i in range(len(begin))]plt.barh(range(len(begin))，end-begin，left = begin)plt.yticks(range(len(begin))，event)plt.show()

请注意，事件 4 和 6 似乎丢失了，因为开始和结束是相同的.如果你想把end解释为年末，你可以加1，

  plt.barh(range(len(begin))，end-begin + 1，left = begin)

I have the type of following data:

Begin   End                        Event
 2003  2007                      Event 1
 1991  2016                      Event 2
 2008  2016                      Event 3
 1986  2015                      Event 4
 2013  2013                      Event 5
 1994  1999                      Event 6
 2002  2002                      Event 7

My goal is to make a timeline of these events, ie to draw a series of distinct straight and horizontal bars from date 1 to date 2 with the names of the events on them.

I am currently trying my luck with the barh function from matplotlib, but I wonder if there is already a ready-made module in python that would integrate nicely with matplotlib and pandas to do so ?

解决方案

I don't think there is the need to for a special function here. Using plt.barh is directly giving you the desired plot.

import matplotlib.pyplot as plt
import numpy as np

begin = np.array([2003,1991,2008,1986,2013,1994,2002])
end =   np.array([2007,2016,2016,2015,2013,1999,2002])
event = ["Event {}".format(i) for i in range(len(begin))]

plt.barh(range(len(begin)),  end-begin, left=begin)

plt.yticks(range(len(begin)), event)
plt.show()

Note that Event 4 and 6 seem missing, because start and end are identical. If you want to interprete end as being the end of the year, you may add 1 to it,

plt.barh(range(len(begin)),  end-begin+1, left=begin)
