在熊猫中创建堆叠的条形图

Question

I am plotting the foll . dataframe using pandas:

╔═════════════════════════════════════════════════════════════════════════╗
║                       country_name              1960s      1970s        ║

╚════════════════════════════════════════════════════════════════════╝

Using the foll . command:

out_dec_df = out_dec_df.set_index('functional_crop_type')
out_dec_df.plot(kind='bar',stacked=True)

However, I want the x-axis to be '1960s', '1970s'...'2010s' and the stacked bar plot to be composed of the functional crop types. How do I do this?

Answer 1

尝试使用转置。

out_dec_df.drop('country_name', axis=1).T.plot(kind='bar',stacked=True)
