只需将此代码放入 Google 的 Visualization Playground 作为示例，我正在使用条形图并编辑工具提示的文本：

function drawVisualization() {
    data = new google.visualization.DataTable()
    data.addColumn('string', 'Date');
    data.addColumn('number');
    data.addColumn({type:'string',role:'tooltip'});
    data.addRow();
    base = 10;
    data.setValue(0, 0, 'Datapoint1');
    data.setValue(0, 1, base++);
    data.setValue(0, 2, " This is my tooltip1 ");

    data.addRow();
    data.setValue(1, 0, 'Datapoint2');
    data.setValue(1, 1, base++);
    data.setValue(1, 2, "This is my second tooltip2");

    // Draw the chart.
    var chart = new google.visualization.BarChart(document.getElementById('visualization'));
    chart.draw(data, {legend:'none', width:600, height:400});
}

似乎有一些关于如何在此处执行此操作的详细信息

http://code.google.com/apis/chart/interactive/docs/examples.html

向下滚动到底部，这是最后一个示例。

将此粘贴到：https ://code.google.com/apis/ajax/playground/?type=visualization#simple_dashboard

  function drawVisualization() {
    // Prepare the data
    var data = new google.visualization.DataTable();
    data.addColumn('string', 'Name');
    data.addColumn('number', 'Donuts eaten');
    data.addColumn({'type': 'string', 'role': 'tooltip', 'p': {'html': true}});

    data.addRows([
      ['Sven', 16, createCustomHTMLContent('https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRnV6emFCNN90Nt-HQcd_x5umqdoSpagUp5fwOqc5QYnVpEHHF8', 16)],

    ]);

     function createCustomHTMLContent(flagURL, totalEaten) {
       return '<div style="padding:5px 5px 5px 5px;">' +
        '<img src="' + flagURL + '" style="width:75px;height:50px"/><br/>' +
        '<table>' +
        '<tr>' +

     }

    // Define a slider control for the 'Donuts eaten' column
    var slider = new google.visualization.ControlWrapper({
      'controlType': 'NumberRangeFilter',
      'containerId': 'control1',
      'options': {
        'filterColumnLabel': 'Donuts eaten',
        'ui': {'labelStacking': 'vertical'}
      }
    });

    // Define a pie chart
    var piechart = new google.visualization.ChartWrapper({
      'chartType': 'ColumnChart',
      'containerId': 'chart1',

          'isHtml': true
        },     
        'pieSliceText': 'value'
      }
    });

    // Create the dashboard.
    new google.visualization.Dashboard(document.getElementById('dashboard')).
      // Configure the slider to affect the piechart
      bind(slider, piechart).
      // Draw the dashboard
      draw(data);
  }

这里有一些带有工具提示的示例

关联

所以有柱形图的例子：

    function drawChart() {
      var dataTable = new google.visualization.DataTable();
      dataTable.addColumn('string', 'Country');
      // Use custom HTML content for the domain tooltip.
      dataTable.addColumn({'type': 'string', 'role': 'tooltip', 'p': {'html': true}});
      dataTable.addColumn('number', 'Gold');
      dataTable.addColumn('number', 'Silver');
      dataTable.addColumn('number', 'Bronze');

      dataTable.addRows([
        ['USA', createCustomHTMLContent('http://upload.wikimedia.org/wikipedia/commons/2/28/Flag_of_the_USA.svg', 46, 29, 29), 46, 29, 29],
        ['China', createCustomHTMLContent('http://upload.wikimedia.org/wikipedia/commons/f/fa/Flag_of_the_People%27s_Republic_of_China.svg', 38, 27, 23), 38, 27, 23],
        ['UK', createCustomHTMLContent('http://upload.wikimedia.org/wikipedia/commons/a/ae/Flag_of_the_United_Kingdom.svg', 29, 17, 19), 29, 17, 19]
      ]);

      var options = {
        title: 'London Olympics Medals',
        colors: ['#FFD700', '#C0C0C0', '#8C7853'],
        // This line makes the entire category's tooltip active.
        focusTarget: 'category',
        // Use an HTML tooltip.
        tooltip: { isHtml: true }
      };

      // Create and draw the visualization.
      new google.visualization.ColumnChart(document.getElementById('custom_html_content_div')).draw(dataTable, options);
    }

    function createCustomHTMLContent(flagURL, totalGold, totalSilver, totalBronze) {
      return '<div style="padding:5px 5px 5px 5px;">' +
          '<img src="' + flagURL + '" style="width:75px;height:50px"><br/>' +
          '<table id="medals_layout">' + '<tr>' +
          '<td><img         src="http://upload.wikimedia.org/wikipedia/commons/1/15/Gold_medal.svg" style="width:25px;height:25px"/></td>' +
