Python 2.7 使用pandas和matplotlib的分组折线图

我有这样一个数据集：

数据集可在以下位置找到：

我想画一个折线图，包含每年的犯罪率。 大概是这样的：
但图中显示了x轴上的连续年份，如2005.5 2007.5。 有人能帮忙吗？或者建议一种更好的方法。谢谢

代码如下：

%matplotlib inline
import pandas as pd
import numpy as np
from matplotlib import pyplot as plt
import plotly.plotly as py
import seaborn as sns

cd =pd.read_clipboard() #after copying the dataset from given url above


        yearRate = cd[['Year','ViolentCrimeRate','MurderRate','RapeRate','RobberyRate','AggravatedAssaultRate','PropertyCrimeRate','BurglaryRate','LarcenyTheftRate','MotorVehicleTheftRate']]
    # These are the "Tableau 20" colors as RGB.    
    tableau20 = [(31, 119, 180), (174, 199, 232), (255, 127, 14), (255, 187, 120),    
                 (44, 160, 44), (152, 223, 138), (214, 39, 40), (255, 152, 150),    
                 (148, 103, 189), (197, 176, 213), (140, 86, 75), (196, 156, 148),    
                 (227, 119, 194), (247, 182, 210), (127, 127, 127), (199, 199, 199),    
                 (188, 189, 34), (219, 219, 141), (23, 190, 207), (158, 218, 229)] 
    for i in range(len(tableau20)):    
        r, g, b = tableau20[i]    
        tableau20[i] = (r / 255., g / 255., b / 255.)  


    plt.figure(figsize=(20,15))
    ax = plt.subplot(111)

    ax.spines['top'].set_visible(False)
    ax.spines['bottom'].set_visible(False)
    ax.spines['left'].set_visible(False)
    ax.spines['right'].set_visible(False)

    plt.ylim(0,5000)
    plt.xlim(1994, 2013)

    plt.yticks(fontsize=14)  
    plt.xticks(fontsize=14)  

    for y in range(0, 5000, 1000):    
        plt.plot(range(1994, 2013), [y] * len(range(1994, 2013)), "--", lw=0.5, color="black", alpha=0)

    rates=['ViolentCrimeRate','MurderRate','RapeRate','RobberyRate','AggravatedAssaultRate','PropertyCrimeRate','BurglaryRate','LarcenyTheftRate','MotorVehicleTheftRate']

    for rank, column in enumerate(rates):    
        # Plot each line separately with its own color, using the Tableau 20    
        # color set in order.    
        plt.plot(yearRate.Year.values,yearRate[column.replace("\n", " ")].values,lw=2.5, color=tableau20[rank])    
        # Add a text label to the right end of every line. Most of the code below    
        # is adding specific offsets y position because some labels overlapped.    
        y_pos = yearRate[column.replace("\n", " ")].values[-1] - 0.5    
        if column == "MotorVehicleTheftRate":    
            y_pos -= 50 
        elif column == "MurderRate":    
            y_pos -= 50 
        plt.text(2013, y_pos, column, fontsize=14, color=tableau20[rank])

添加：

plt.xticks(cd['Year'])

解决了这个问题。

你能提供一个简单的例子吗？特别是如果有一些可复制粘贴的代码就更好了。@ArcoBast你想让我将代码粘贴到这里还是数据集？你能在你的原始帖子中编辑它，这样我就可以复制粘贴代码并立即运行吗？对不起，这个复制粘贴步骤对我不起作用。可能您想签出此链接：您需要从提供的链接复制数据集（它将保存在clipbaord中）：然后运行代码，读取）剪贴板（）将从clipbaord加载数据
