Properties​

figure​

Matplotlib figure to draw - an instance of matplotlib.figure.Figure class.

isolated​

Every time when a page or parent chart control are updated with page.update() or Control.update() methods respectively the chart is re-drawn by calling Matplotlib API. Frequent re-drawings of large charts could affect the performance of the entire Flet app.

Set isolated to True to enable explicit chart updates. To re-draw the chart call its update() method. For example the first example on this page could be modified as following:

def main(page: ft.Page):

    # ...

    # set initial axis legent
    ax.legend(title="Fruit color")

    # enable explicit updates
    # and add chart to a page
    chart1 = MatplotlibChart(fig, isolated=True, expand=True)
    page.add(chart1)

    sleep(5)

    # update chart axis
    ax.legend(title="Colors")
    chart1.update()

ft.app(main)
