pyxll-dash 0.0.1

Adds Plotly Dash support to PyXLL for integrating Dash apps into Microsoft Excel.

PyXLL-Dash

Plotly Dash Integration for Microsoft Excel.

See the Plotly Dash Apps In Excel.

Installation

To install this package use:

pip install pyxll-dash

The PyXLL Excel add-in must also be installed. See PyXLL.

Usage

Once installed, the pyxll.plot function can be called with a dash app object.

Calling pyxll.plot with a dash app object from a PyXLL function will display the app in an embedded web control in Excel in the same way as other supported PyXLL plot types.

See PyXLL Plotting for details of how to use the pyxll.plot function.

Example

from pyxll import xl_func, plot
from dash import Dash, html, dcc, callback, Output, Input
import plotly.express as px
import pandas as pd


@xl_func
def dash_app():

    df = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/gapminder_unfiltered.csv')

    app = Dash()

    app.layout = [
        html.H1(children='Title of Dash App', style={'textAlign':'center'}),
        dcc.Dropdown(df.country.unique(), 'Canada', id='dropdown-selection'),
        dcc.Graph(id='graph-content')
    ]

    @app.callback(
        Output('graph-content', 'figure'),
        Input('dropdown-selection', 'value')
    )
    def update_graph(value):
        dff = df[df.country==value]
        return px.line(dff, x='year', y='pop')

    # Show the dash app in Excel using PyXLL's plot function.
    # This requires the "pyxll-dash" package to be installed.
    plot(app)

    return app
