javascript - 从图表的开始到结束绘制的图表上自动触发鼠标单击事件？

Question

    graph1 = new links.Graph(document.getElementById('adasLineChart1'));
    graph1.draw(data1, options1);


    links.events.addListener(graph1, "selectItem", function(event) {

    });

我正在寻找类似于图形鼠标单击事件的自动触发，从图形的开始到结束，无需手动单击鼠标，示例：

function counter(){

//trigger graph event similar to mouse on click event.
}
