python3 selenium K线图 拖动ActionChains

我就是举个例子，selenium 的 Actionchains使用可以参考这篇博客https://blog.youkuaiyun.com/jamieblue1/article/details/89856576

def canvas_move_right(self,move_d = 0):
        driver = self.driver
        actions = ActionChains(driver)
        try:
            if move_d <= self.width:
                actions.move_to_element_with_offset(self.canvas, 0,0.5*self.height).perform()
                time.sleep(0.2)
                actions.click_and_hold(self.canvas).perform()
                time.sleep(0.2)
                actions.move_to_element_with_offset(self.canvas, move_d , 0.5 * self.height).perform()
                time.sleep(0.2)
                actions.move_to_element_with_offset(self.canvas, move_d , 0.5 * self.height).click().perform()
            else:
                print("一次移动距离过大，移动失败")
        except Exception as Erro:
            print(Erro)
