canvasxpress-dash

CanvasXpress interactive charts in Dash apps — no JavaScript build step. CanvasXpress(...) returns a self-contained html.Iframe that loads the library from the CanvasXpress CDN and renders one chart.

Install

pip install canvasxpress-dash

Use

from dash import Dash, html
from canvasxpress_dash import CanvasXpress

app = Dash(__name__)

app.layout = html.Div([
    html.H2("CanvasXpress in Dash"),
    CanvasXpress(
        data={
            "y": {
                "vars": ["Revenue"],
                "smps": ["Q1", "Q2", "Q3", "Q4"],
                "data": [[10, 14, 9, 17]],
            }
        },
        config={"graphType": "Bar", "title": "Quarterly Revenue"},
        height=420,
    ),
])

if __name__ == "__main__":
    app.run(debug=True)

data and config are exactly the arguments of new CanvasXpress({...}) in JavaScript, so any spec from the gallery or the R / Python packages works unchanged.

Parameters

Extra keyword arguments (className, style, …) pass through to the underlying html.Iframe.
