我正在使用Pandas和Matplotlib进行可视化。我在创建图表时遇到了麻烦,即使我觉得我拥有了所有需要的信息。
from matplotlib import rcParams
%matplotlib inline
rcParams['figure.figsize'] = 5, 4
sb.set_style('ticks')
B = df.groupby(['DATE']).BOROUGH.value_counts()

如何绘制这个子集,其中x是日期,每个Borough在同一图表上形成一条单独的行?
答案 0 :(得分:0)
你可以取消堆叠你的系列并将其绘制为常规DF:
B.unstack().plot()
“拆散”的结果:
In [41]: B.unstack()
Out[41]:
