这个奇怪的东西让我看到水平线上只有4个网格线。任何人都可以帮忙吗？Google Chart - date＆gridlines

<html>

    <script type="text/javascript"> 
     google.load("visualization", "1", {packages:["corechart"]}); 
     google.setOnLoadCallback(drawChart); 
     function drawChart() { 
     var data = new google.visualization.DataTable(); 
    data.addColumn('date', 'Date'); 
    data.addColumn('number', 'Now'); 
    data.addColumn('number', 'Comparison'); 
    data.addRows([ 
    [new Date(2008, 1 ,1), 1264,  1477],

图表的默认行为是使用5个网格线。请参阅the documentation下的hAxis.gridlines.count。

如果要增加网格线的数量，请在图表中设置选项。例如：

chart.draw(data, {vAxis: {gridlines: {count: 100}}})

这里是网格线的整个混乱的样品（来自谷歌游乐场上述选项添加）：

function drawVisualization() { 
    // Create and populate the data table. 
    var data = google.visualization.arrayToDataTable([ 
    ['x', 'Cats', 'Blanket 1', 'Blanket 2'], 
    ['A', 1,  1,   0.5], 
    ['B', 2,  0.5,   1], 
    ['C', 4,  1,   0.5], 
    ['D', 8,  0.5,   1], 
    ['E', 7,  1,   0.5], 
    ['F', 7,  0.5,   1], 
    ['G', 8,  1,   0.5], 
    ['H', 4,  0.5,   1], 
    ['I', 2,  1,   0.5], 
    ['J', 3.5,  0.5,   1], 
    ['K', 3,  1,   0.5], 
    ['L', 3.5,  0.5,   1], 
    ['M', 1,  1,   0.5], 
    ['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, gridlines: {count: 100}} 
       } 
     ); 
}

当你没有指定你有多少网格线预计，请编辑上述内容以满足您的需求。
