[英]bar chart over pandas DataFrame
I have dataframe like this: 我有这样的数据框:
Continent Surplus1980 Surplus1985 ... Surplus2005 Surplus2010
Africa -711.186834 -894.362995 ... -1001.189049 -960.203280
Asia -1464.995609 -1528.688190 ... -1511.834129 -1529.459409
Europe 716.832130 580.341819 ... 574.808741 590.688746
North America 1586.628358 2559.054466 ... 2851.819722 2867.880633
Oceania 4163.456825 3899.532718 ... 3807.652781 3796.396563
South America 1455.955084 1196.506188 ... 1086.940969 1093.484142
Now I want to plot a bar-chart that shows each continent value from 1980 to 2010 in the x-axis. 现在,我想绘制一个条形图,在x轴上显示1980年至2010年每个大陆的价值。 I am using this function:
我正在使用此功能:
df.plot(kind="bar", rot=0, ax=ax, width=0.5)
my result shows me: 我的结果告诉我:
bar-chart 柱形图
So how I can change to have continent name in the legend and for each year shows me the value of each continent? 那么,如何在图例中更改大陆名称,并每年向我展示每个大陆的价值?
