How To Plot Sorted Barplot In Plolty3.10

I have been trying to plot sorted barplot in plotly for some stores sales data, but whatever I try it gives me the unsorted data. How to plot the sorted barplot using plotly. NOTE:

Solution 1:

The correct key to use for this is layout.xaxis.categoryorder, with the value "total ascending", but it only applies when the layout.xaxis.type is "category". This happens automatically if your x array contains strings, but if your x contains only numbers you'll have to set it manually.

Here is a version of your barplot function as recommended:

def barplot(x,y):
    data = [go.Bar(
        x=x,
        y=y,
        marker={
            'color': y,
            'colorscale': 'Reds'
        }
    )]

    layout = {
        'xaxis': {
            'tickvals': x,
            'ticktext': ['store ' + str(i) for i in x],
            'tickangle': 40,
            'type': "category",
            'categoryorder': 'total ascending'
        }
    }

    fig = go.FigureWidget(data=data, layout=layout)

    return iplot(fig)
