这是我的图表的简化版本:
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var jsonData = '{"cols":[{"id":"","label":"date","type":"string"},{"id":"","label":"a","type":"number"},{"id":"","label":"b","type":"number"}],"rows":[{"c":[{"v":"2012-05-01"},{"v":"1"},{"v":"8"}]},{"c":[{"v":"2012-05-02"},{"v":"1"},{"v":"7"}]},{"c":[{"v":"2012-05-03"},{"v":"1"},{"v":"38"}]}]}';
var data = new google.visualization.DataTable(jsonData);
var options = {
title : 'Company Performance',
pointSize : 5,
chartArea: {width: 800, height: 800},
width: 800+300, height: 800+600,
legend:{position: 'bottom',maxLines: 3},
vAxis: {direction:-1, minValue: 1, viewWindowMode: 'explicit', viewWindow:{min:1}},
colors : ['#0E9DFF','#9616F3']
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="chart_div" style="width: 900px; height: 500px;"></div>
</body>
</html>
我的目标是将vAxis的最小值设置为0 它有效,但如何显示它? 以及如何将水平轴移动到底部?
