谷歌图表轴标题

Question

是否可以在谷歌图表（折线图）上添加轴标题，而不是更改刻度标记？

Tnx in adv！

是的，你可以。这里有一个稍微修改的例子： http://code.google.com/apis/ajax/playground/?type=visualization#line_chart

诀窍是获取两个垂直轴的轴标签（还没有想出如何做到这一点）。

<script type="text/javascript" src="http://www.google.com/jsapi"></script> 
<script type="text/javascript"> 
    google.load('visualization', '1', {packages: ['corechart']}); 
</script> 
<script type="text/javascript"> 
    function drawVisualization() { 
    // Create and populate the data table. 
    var data = new google.visualization.DataTable(); 
    data.addColumn('string', 'x'); 
    data.addColumn('number', 'Cats'); 
    data.addColumn('number', 'Blanket 1'); 
    data.addColumn('number', 'Blanket 2'); 
    data.addRow(["A", 1, 1, 0.5]); 
    data.addRow(["B", 2, 0.5, 1]); 
    data.addRow(["C", 4, 1, 0.5]); 
    data.addRow(["D", 8, 0.5, 1]); 
    data.addRow(["E", 7, 1, 0.5]); 
    data.addRow(["F", 7, 0.5, 1]); 
    data.addRow(["G", 8, 1, 0.5]); 
    data.addRow(["H", 4, 0.5, 1]); 
    data.addRow(["I", 2, 1, 0.5]); 
    data.addRow(["J", 3.5, 0.5, 1]); 
    data.addRow(["K", 3, 1, 0.5]); 
    data.addRow(["L", 3.5, 0.5, 1]); 
    data.addRow(["M", 1, 1, 0.5]); 
    data.addRow(["N", 1, 0.5, 1]); 

    // Create and draw the visualization. 
    new google.visualization.LineChart(document.getElementById('visualization')). 
     draw(data, {curveType: "function", 
        width: 500, height: 400, 
        vAxis: {maxValue: 10, title: "my Axis"}} 
      ); 
    } 


    google.setOnLoadCallback(drawVisualization); 
</script>
