    $ cd Flask-Plots
    $ python3 -m venv venv
    $ source venv/bin/activate
    (venv) $ pip install -r requirements/dev.txt

Quick start

With Flask-Plots you can instance the Plots object and document your endpoints.

    from flask import Flask, render_template_string
    from flask_plots import Plots
    import matplotlib
    from matplotlib.figure import Figure
    import numpy as np
    
    app = Flask(__name__)
    plots = Plots(app)

    # routes
    @app.route("/")
    def bar():
        # Make data:
        countries = ["Argentina", "Brasil", "Colombia", "Chile"]
        peoples = [14, 40, 16, 24]
        # Plot:
        fig = Figure()
        ax = fig.subplots()
        ax = plots.bar(fig, countries, peoples)
        ax.set_title("Bar Chart")
        data = plots.get_data(fig)
        return render_template_string(
                """
                {% from 'plots/utils.html' import render_img %}
                {{ render_img(data=data, alt_img='my_img') }}
                """,
                data=data
            )

    if __name__ == "__main__":
        app.run(port=5000, debug=True)
