Tkinter界面实时绘制函数图像：如何实现按钮控制电路的断开与闭合并从点击时刻开始绘制？

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

    # 进行状态切换
    self.simulator.switch_states[current_index] = not self.simulator.switch_states[current_index]

    # 更新按钮文本和命令

        self.manual_switch_button["text"] = "Open Circuit"
    else:
        self.manual_switch_button["text"] = "Close Circuit"

    # 更新整个图表，传递当前时间点的索引
    self.update_plot(current_index)
    self.canvas.draw_idle()

    # 检查当前时间点是否有开关切换发生
    if current_time_index > self.previous_switch_time_index:
        # 检查当前时间点的开关状态是否与前一时刻不同
        if self.switch_states[current_time_index] != self.switch_states[current_time_index - 1]:
            self.previous_switch_state = not self.previous_switch_state
            next_switch_index = current_time_index + np.argmax(
                self.switch_states[current_time_index:] != self.switch_states[current_time_index])
            if not self.previous_switch_state:

    V_circuit = self.simulator.VoltageOverTime[:frame + 1]
    I_circuit = self.simulator.CurrentOverTime[:frame + 1]

    self.V_line.set_data(t[:len(V_circuit)], V_circuit)

    self.axs[0].set_ylim(0, 20)
    self.axs[1].set_ylim(0, 2)
    print("Plot updated")  # 添加这行代码来确认图表是否被更新
