谷歌图表 vAxis

Question

我在对象 vAxis 中使用 Combo Chart google 构建图形并显示在一个地方我为每个图表设置了颜色和名称：

vAxes: {
    0: {
        title:'График 1',
        textStyle: {color: '#21C40A'},
        minorGridlines: {count: 2, color: '#ccc'},
        titleTextStyle: {color: '#21C40A'},
    },
    1: {
        title:'График 2',
        textStyle: {color: '#E89712'},
        minorGridlines: {count: 2, color: '#ccc'},
        titleTextStyle: {color: '#E89712'}
    },
    2: {
        title:'График 3',
        textStyle: {color: '#390983'},
        minorGridlines: {count: 2, color: '#ccc'},
        titleTextStyle: {color: '#390983'}
    }
}

问题是如何指定 y 坐标的位置或取彼此之间的距离，以使数据不会相互堆叠？ 我可以这样得到吗？

Answer 1

在右侧轴之一上，
设置 --> textPosition: 'in'

这将在图表内移动一个，否则，
它们将永远堆叠在一起......

请参阅以下工作 sn-p，
还可以使用chartArea.right 为标签和标题留出足够的空间......

google.charts.load('current', {
  callback: function () {
    var data = new google.visualization.DataTable();
    data.addColumn('date', 'Month');
    data.addColumn('number', "Average Temperature");
    data.addColumn('number', "Average Hours of Daylight");
    data.addColumn('number', "Average 1");
    data.addColumn('number',"Average 2")
    data.addRows([
      [new Date(2014, 0),  -.5,  8.7,7,11],
      [new Date(2014, 1),   .4,  8.7,5,12],
      [new Date(2014, 2),   .5,   12,6,13],
      [new Date(2014, 3),  2.9, 15.7,5,14],
      [new Date(2014, 4),  6.3, 18.6,8,15],
      [new Date(2014, 5),    9, 20.9,8,16],
      [new Date(2014, 6), 10.6, 19.8,9,16],
      [new Date(2014, 7), 10.3, 16.6,7,15],
      [new Date(2014, 8),  7.4, 13.3,8,14],
      [new Date(2014, 9),  4.4,  9.9,12,13],
      [new Date(2014, 10), 1.1,  6.6,11,12],
      [new Date(2014, 11), -.2,  4.5,11,11]
    ]);

    var classicOptions = {
      title: 'Average Temperatures and Daylight in Iceland Throughout the Year',
      width: '100%',
      height: '100%',
      chartArea: {
        width: '100%',
        height: '100%',
        top: 72,
        left: 60,
        bottom: 48,
        right: 84
      },
      series: {
        0: {targetAxisIndex: 0},
        1: {targetAxisIndex: 1},
        2: {targetAxisIndex: 2}
      },
      vAxes: {
        0: {
          textPosition: 'out',
          title: 'Temps (Celsius)'
        },
        1: {
          textPosition: 'out',
          title: 'Daylight',
          viewWindow: {
            max: 30
          }
        },
        2: {
          textPosition: 'in',
          title: 'third',
          viewWindow: {
            max: 40
          }
        }
      },
      hAxis: {
        ticks: [
          new Date(2014, 0), new Date(2014, 1), new Date(2014, 2), new Date(2014, 3),
          new Date(2014, 4),  new Date(2014, 5), new Date(2014, 6), new Date(2014, 7),
          new Date(2014, 8), new Date(2014, 9), new Date(2014, 10), new Date(2014, 11)
        ]
      },
    };

    var classicChart = new google.visualization.LineChart(document.getElementById('chart_div'));
    classicChart.draw(data, classicOptions);
  },
  packages:['corechart']
});
