Google 图表消除 space

Google charts eliminate space

是否可以消除每两个柱之间的 space 然后添加 space?

看我的例子:

google.load('visualization', '1', {packages: ['corechart', 'bar']});
google.setOnLoadCallback(drawBasic);

function drawBasic() {

  var data = new google.visualization.DataTable();
  data.addColumn('string', 'Time of Day');
  data.addColumn('number', 'Motivation Level');

  data.addRows([
    ["6/4/2015", 10] ,
      ["13/4/2015", 10] ,
      ["7/4/2015", 20] ,
      ["14/4/2015", 10] ,
    ["8/4/2015", 10] ,
  ]);

  var chart = new google.visualization.ColumnChart(
    document.getElementById('chart_div'));

  chart.draw(data, null);
}

看看下面的fiddle。在代码中,我添加了 options 数组并将 bar 值设置为 99%。这按照您的要求减少了间距(我相信)。

var options = {
    bar: {
        groupWidth: "99%"
    },
};

chart.draw(data, options);
