如何按降序对 Plotly 条形图进行排序

I have created a basic bar chart in plotly that I would like to sort by descending order.

我找不到在绘图语法中指定这一点的简单方法，因此我尝试使用 Pandas 修改数据框。这也没有奏效。

我的代码如下：

import plotly.plotly as py
import plotly.graph_objs as go
import pandas as pd


df = pd.read_csv('C:/Users/Documents/Python/CKANMay.csv')
sd = df.nlargest(3,'Views')
fd = sd.sort_values(by='Views', ascending = False)


my_data = [go.Bar( x = fd.Views, y = fd.Publisher, orientation = 'h')]
my_layout = ({"title": "Most popular publishers",
                       "yaxis": {"title":"Publisher"},
                       "xaxis": {"title":"Views"},
                       "showlegend": False})

fig = go.Figure(data = my_data, layout = my_layout)

py.iplot(fig)

我想反转条形图，以便具有最大值的列位于顶部。感谢您的任何帮助。

添加这个来更新你的数字：

fig.update_layout(barmode='stack', xaxis={'categoryorder':'total descending'})
