可以从折线图谷歌图表中的点向下画一条线(虚线和直线)吗?
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales'],
['2004', 1000],
['2005', 1170],
['2006', 660],
['2007', 1030]
]);
var options = {
title: 'Company Performance',
pointSize: 10
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
这个概念是这样的......
