I have created a basic bar chart in plotly that I would like to sort by descending order.
I couldn't find an easy way to specify this in the plotly syntax, so I tried modifying the dataframe with Pandas. This also hasn't worked.
My code is below:
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)
I would like to invert the bar chart, so that the column with the greatest value is on the top. Appreciative for any assistance.

Maximilian Peters almost 5 yearsCan you try 'ascending=True`? Plotly just plots the values in the same order as the come.
