Javascript google 图表设置

Question

我有以下图表。我希望图表旁边和图表上的单位都有一个空的“”作为千位分隔符。我希望数字后跟单位，例如“100,000 美元”。有什么建议吗？

Answer 1

首先，格式化程序不适用于数据视图。
因此您需要在构建视图之前格式化数据 table。

接下来，没有模式允许 space 字符用作分隔符。
从格式化程序中删除 pattern 选项。

  var formatter = new google.visualization.NumberFormat({
    groupingSymbol: ' ',
    suffix: ' Kč',
    fractionDigits: 0,
    prefix: '$'
  });

并且您需要格式化所有数字列...

  formatter.format(data, 1);
  formatter.format(data, 2);
  formatter.format(data, 3);

接下来，为了格式化注释，您需要使用格式化程序的 formatValue 方法。
并将注释类型更改为 'string'

  view.setColumns([0,
    1, {
      calc: function(dt, row) {
        return formatter.formatValue(dt.getValue(row, 1));  // <-- use formatValue
      },
      type: "string",
      role: "annotation",
    },

并且由于您是在数据视图中添加注释，
注释列可以从数据中删除 table.

最后，由于模式不起作用，
格式化 v 轴标签的唯一方法是提供您自己的自定义刻度。

ticks 选项需要一个值数组。
在这种情况下，我们需要使用对象表示法，
提供报价单的值 (v:)，
和格式化值 (f:)

ticks: [{v: 0, v: '0'}, {v: 100000, f: '100 000 Kč'}, {v: 200000, f: '200 000 Kč'}, ...]

请参阅以下工作片段...

google.charts.load('current', {
  packages: ['corechart']
});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {

  var data = google.visualization.arrayToDataTable([
    ['Genre', 'Vk', 'Sta', 'Va'],
    ['Ps', 360000, 82000, 200000],
    ['Ds', 360000, 82000, 200000]
  ]);

  var formatter = new google.visualization.NumberFormat({
    groupingSymbol: ' ',
    suffix: ' Kč',
    fractionDigits: 0,
    prefix: '$'
  });
  formatter.format(data, 1);
  formatter.format(data, 2);
  formatter.format(data, 3);


  var view = new google.visualization.DataView(data);

  view.setColumns([0,
    1, {
      calc: function(dt, row) {
        return formatter.formatValue(dt.getValue(row, 1));
      },
      type: "string",
      role: "annotation",
    },
    2, {
      calc: function(dt, row) {
        return formatter.formatValue(dt.getValue(row, 2));
      },
      type: "string",
      role: "annotation"
    },
    3, {
      calc: function(dt, row) {
        return formatter.formatValue(dt.getValue(row, 3));
      },
      type: "string",
      role: "annotation"
    },
  ]);

  var options = {
    title: '',
    isStacked: true,
    //pieSliceText: 'value',
    legend: {
      position: 'right'
    },
    chartArea: {
      left: "12%",
      top: "4%",
      height: "92%",
      width: "70%"
    },
    colors: ['#3366CC', '#DC3912', '#23C228', '#000000'],
    vAxis: {
      ticks: [{v: 0, v: '0'}, {v: 100000, f: '0 000 Kč'}, {v: 200000, f: '0 000 Kč'}, {v: 300000, f: '0 000 Kč'}, {v: 400000, f: '0 000 Kč'}, {v: 500000, f: '0 000 Kč'}, {v: 600000, f: '0 000 Kč'}, {v: 700000, f: '0 000 Kč'}]
    }
  };

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

  chart.draw(view, options);

  document.getElementById("j_idt26:chart").value = chart.getImageURI();
}
