谷歌图表vAxis在右边

Question

我正在使用谷歌可视化

var data2 = new google.visualization.DataTable();
        data2.addColumn('string', 'time');
        data2.addColumn('number', 'amount');
        data2.addColumn({ type: 'string', role: 'tooltip' });
        data2.addRows(rows_data);
        var options2 = {
            vAxis: { textPosition: 'none', title: '', textStyle: { fontName: 'arial'} },
            hAxis: { slantedText: false, textStyle: { color: '#E6EFFA' }, gridlines: { color: '#E6EFFA', count: 20} },
            backgroundColor: '#E6EFFA',
            legend: 'none',
            chartArea: { top: 0 },
            colors: ['#435988'],
            chartArea: { width: 800 }
        };
        chart2 = new google.visualization.LineChart(document.getElementById('chart_div_volume'));

我希望vAxis的位置在右边.可能吗 ？

简答:是的,但这很棘手.

答案很长:

您需要设置多轴图表.基本上,您创建一个没有标签或任何东西的虚拟轴,使其看起来像一个轴.然后配置辅助轴.您可以创建一组虚拟值(隐藏)以放在第一个轴上,并在第二个轴上绘制实际数据.

这是一个例子:

function drawVisualization() {
  // Create and populate the data table.
  var data = google.visualization.arrayToDataTable([
    ['Year', 'Dummy', 'Sales', 'Expenses'],
    ['2004',  0,   1000,      400],
    ['2005',  null,   1170,      460],
    ['2006',  null,   660,       1120],
    ['2007',  null,   1030,      540]
  ]);

  var options = {
    title: 'Company Performance',
    series: { 0: {targetAxisIndex: 0, visibleInLegend: false, pointSize: 0, lineWidth: 0},
              1: {targetAxisIndex: 1},
              2: {targetAxisIndex: 1}
             },
    vAxes: {
      0: {textPosition: 'none'},
      1: {},
    }
  };

  var chart = new google.visualization.LineChart(document.getElementById('visualization'));
  chart.draw(data, options);
}
