简单定制matplotlib/pandas条形图(标签，刻度等) [英] Simple customization of matplotlib/pandas bar chart (labels, ticks, etc.)

问题描述

我是matplotlib的新手，我试图在熊猫中使用它来绘制一些简单的图表.我有一个DataFrame，其中包含两个标签"score"和"person"，它们是从另一个DF派生的.

I am new to matplotlib and I am trying to use it within pandas to plot some simple charts. I have a DataFrame that contains two labels "score" and "person", derived from another DF.

df1 = DataFrame(df, columns=['score','person'])

产生此输出:

我正在尝试创建一个简单的条形图，以用不同的颜色显示每个人，这是我到目前为止所拥有的:

I am trying to create a simple bar chart, to show each person in different color, and this is what I have thus far:

df1.plot(kind='bar', title='Ranking')

如何对其进行自定义，以使图表在x轴上以唯一的颜色显示人员姓名，并删除图形周围的框架"?如何使其成为水平条形图?

How can I customize it so the chart shows the person names in the x axis with unique colors and remove the "frame" surrounding the figure? How can I make it a horizontal bar chart?

预先感谢您的帮助.

推荐答案

我想这会给你一个想法:

I guess this will give you the idea:

df = pd.DataFrame({'score':np.random.randn(6),
                   'person':[x*3 for x in list('ABCDEF')]})

ax = plt.subplot(111)
df.score.plot(ax=ax, kind='barh', color=list('rgbkym'), title='ranking')
ax.axis('off')
for i, x in enumerate(df.person):
    ax.text(0, i + .5, x, ha='right', fontsize='large')

为

  person  score
0    AAA   1.79
1    BBB   0.31
2    CCC  -0.52
3    DDD   1.59
4    EEE   0.59
5    FFF  -1.03
