📦 安装

pip install tkchart

import tkchart

🚀 快速开始

import tkinter as tk
import tkchart
import random
import threading
import time

root = tk.Tk()

# 1. 创建图表
chart = tkchart.LineChart(
    master=root,
    x_axis_values=("a", "b", "c", "d", "e", "f"),
    y_axis_values=(100, 900)
)
chart.place(x=10, y=10)

# 2. 创建折线
line = tkchart.Line(master=chart)

# 3. 在后台线程中持续推送数据
def loop():
    while True:
        chart.show_data(line=line, data=[random.choice(range(100, 900))])
        time.sleep(1)

threading.Thread(target=loop, daemon=True).start()
root.mainloop()
