Tkinter模拟电路：如何让按钮点击实时更新函数图像并控制电路开关？

# 如果当前时刻开关状态与上一时刻不同
if self.switch_states[current_time_index] != self.switch_states[current_time_index - 1]:
    # 更新上一个开关状态
    self.previous_switch_state = not self.previous_switch_state

    # 找到下一个开关状态变化的时间点
    next_switch_index = current_time_index + np.argmax(
        self.switch_states[current_time_index:] != self.switch_states[current_time_index])

    # 根据当前开关状态更新电压和电流数组
    if not self.previous_switch_state:
        # 开关断开
        self.voltageovertime[current_time_index:] = 0
        self.currentovertime[current_time_index:] = 0
    else:
        # 开关闭合
        self.voltageovertime[current_time_index:] = v_battery * np.ones_like(
            self.voltageovertime[current_time_index:])
        self.currentovertime[current_time_index:] = v_battery / r_load * np.ones_like(
            self.currentovertime[current_time_index:])

    # 更新上一次开关切换的时间索引
    self.previous_switch_time_index = next_switch_index

def toggle_manual_switch(self):
    # 获取当前时刻的索引
    current_time_index = int(self.current_time_index)

    # 切换开关状态
    self.simulator.toggle_switch_at_time(current_time_index)
    self.simulator.calculate_circuit_response(current_time_index)

    # 更新按钮文本和命令
    # ... 省略 ...

    # 更新图表，传递当前时刻的索引
    self.update_plot(current_time_index)
    self.canvas.draw_idle()

def update_plot(self, frame):
    # 计算电路响应
    self.simulator.calculate_circuit_response(frame)

    # 获取当前时间和电压、电流数据
    time = t[frame]
    V_circuit = self.simulator.VoltageOverTime
    I_circuit = self.simulator.CurrentOverTime

    # 更新图表数据
    self.V_line.set_data(t, V_circuit)
    self.I_line.set_data(t, I_circuit)

    # 设置坐标轴范围
    # ... 省略 ...

    # 打印提示信息
    print("Plot updated")
    print("Plot Voltage:", V_circuit[-1], "V")

    return self.V_line, self.I_line
