Code sample

Code

import matplotlib
import matplotlib.pyplot as plt
import numpy as np

import flet as ft
from flet.matplotlib_chart import MatplotlibChart

matplotlib.use("svg")

def main(page: ft.Page):

    # Fixing random state for reproducibility
    np.random.seed(19680801)

    dt = 0.01
    t = np.arange(0, 30, dt)
    nse1 = np.random.randn(len(t))  # white noise 1
    nse2 = np.random.randn(len(t))  # white noise 2

    # Two signals with a coherent part at 10Hz and a random part
    s1 = np.sin(2 * np.pi * 10 * t) + nse1
    s2 = np.sin(2 * np.pi * 10 * t) + nse2

    fig, axs = plt.subplots(2, 1)
    axs[0].plot(t, s1, t, s2)
    axs[0].set_xlim(0, 2)
    axs[0].set_xlabel("time")
    axs[0].set_ylabel("s1 and s2")
    axs[0].grid(True)

    cxy, f = axs[1].cohere(s1, s2, 256, 1.0 / dt)
    axs[1].set_ylabel("coherence")

    fig.tight_layout()
    
    chart = MatplotlibChart(fig, expand=True)

    #page.add(chart)
    
    def on_button_click(e):
    
        plt.cla()
        #plt.clf()
    
        # Fixing random state for reproducibility
        np.random.seed(23412)
        
        dt = 0.01

        s1 = np.sin(2 * np.pi * 10 * t) + nse1
        s2 = np.sin(2 * np.pi * 10 * t) + nse2
        
        fig, axs = plt.subplots(1, 1)
        #axs[0].plot(t, s1, t, s2)
        #axs[0].set_xlim(0, 2)
        #axs[0].set_xlabel("timesssss")
        #axs[0].set_ylabel("s2 and s1")
        #axs[0].grid(True)
        
        #cxy, f = axs[0].cohere(s1, s2, 256, 1.0 / dt)
        #axs[0].set_ylabel("coherence")

        cxy, f = axs.cohere(s1, s2, 256, 1.0 / dt)
        axs.set_ylabel("coherence")
       
        fig.tight_layout()  
    
        #chart.update()
        
        page.update()
    
    page.add(
        ft.ElevatedButton("Update Stock Chart", on_click=on_button_click),
        chart
    )    

ft.app(main)

To reproduce

1. build my-app (flet build apk -vv)
2. Copy apk-file to my android-phone.
3. Installed my-app in android-phone.
4. Click my-app.
