Using Pandas Value_Counts and matplotlib
提问by W4K1NG
I have used Pandas's value_counts function to provide counts of unique values:
我使用 Pandas 的 value_counts 函数来提供唯一值的计数:
CountStatus = pd.value_counts(df['scstatus'].values, sort=True)
Output:
200 133809
304 7217
404 2176
302 740
500 159
403 4
301 1
dtype: int64
I now want to plot these values using matplotlib i.e "plt.barh(CountStatus)", however I keep getting the error: ValueError: incompatible sizes: argument 'width' must be length 7 or scalar.
我现在想使用 matplotlib 即“plt.barh(CountStatus)”绘制这些值,但是我不断收到错误:ValueError:不兼容的大小:参数“宽度”必须是长度 7 或标量。
I'm guessing this may have something to do with the left hand column being an index column. Is there a way around this to obtain a horizontal bar chart? Do I need to convert it or specify something else in the function?
我猜这可能与作为索引列的左侧列有关。有没有办法解决这个问题来获得水平条形图?我是否需要转换它或在函数中指定其他内容?
Thanks
