highcharts - 更改 HighCharts 中成交量列（高/低）的颜色

Question

我有一个简单的图表，显示烛台下方的交易量列：http: //jsfiddle.net/T83Xy/

基本上，我想根据收盘价是否高于开盘价，对列使用黑色和红色。我通过推 Y: data, color: '#000000' 作为参数看到了一些示例。问题是我正在推送日期和卷号。我试图推送 X: date, Y: data, color: '#000000' 但它抛出错误并且没有给我预期的结果。

首先，如果您有大量积分，您需要将series.turboThreshold设置为 0。这将禁用输入数据格式检查。

然后，要根据蜡烛应用列颜色，我建议您使用这段代码：

Highcharts.seriesTypes.column.prototype.pointAttribs = (function(func) {
    return function(point, state) {
      var attribs = func.apply(this, arguments);
      
      var candleSeries = this.chart.series[0]; // Probably you'll need to change the index
      var candlePoint = candleSeries.points.filter(function(p) { return p.index == point.index; })[0];

      var color = (candlePoint.open < candlePoint.close) ? '#FF0000' : '#000000'; // Replace with your colors
      attribs.fill = state == 'hover' ? Highcharts.Color(color).brighten(0.3).get() : color;
      
      return attribs;
    };
}(Highcharts.seriesTypes.column.prototype.pointAttribs));

请小心，因为此代码会影响当前页面上的所有图表。但是您可以轻松添加一些条件以仅在特定图表上运行它。这是带有上述代码的默认 Highstock 演示。

这对我来说非常有效：

$(function () {
jQuery.getJSON('https://www.highcharts.com/samples/data/jsonp.php?filename=aapl-ohlcv.json&callback=?', function (data) {

    // split the data set into ohlc and volume
    var volumeColor = '';
    var ohlc = [],
        volume = [],
        dataLength = data.length,
        // set the allowed units for data grouping
        groupingUnits = [[
            'week',                         // unit name
            [1]                             // allowed multiples
        ], [
            'month',
            [1, 2, 3, 4, 6]
        ]],

        i = 0;

    for (i; i < dataLength; i += 1) {
        ohlc.push([
            data[i][0], // the date
            data[i][1], // open
            data[i][2], // high
            data[i][3], // low
            data[i][4] // close
        ]);
         if (i==0) {
        volumeColor = '#CCCCCC';
         } else {         
            if (data[i][1] >= data[i-1][1]) {
               volumeColor = '#006633';
            } else {
               volumeColor = '#CC0033';
            }
         }

        volume.push({
            x: data[i][0], // the date
            y: data[i][5],
            color: volumeColor
        });
    }


    // create the chart
    $('#container').highcharts('StockChart', {

        rangeSelector: {
            selected: 1
        },

        title: {
            text: 'AAPL Historical'
        },

        yAxis: [{
            labels: {
                align: 'right',
                x: -3
            },
            title: {
                text: 'OHLC'
            },
            height: '60%',
            lineWidth: 2
        }, {
            labels: {
                align: 'right',
                x: -3
            },
            title: {
                text: 'Volume'
            },
            top: '65%',
            height: '35%',
            offset: 0,
            lineWidth: 2
        }],

        series: [{
            type: 'candlestick',
            name: 'AAPL',
            data: ohlc,
            dataGrouping: {
                units: groupingUnits
            }
        }, {
            type: 'column',
            name: 'Volume',
            data: volume,
            yAxis: 1,
            turboThreshold: Number.MAX_VALUE,
            dataGrouping: {
                enabled: false,
                units: groupingUnits
            }
        }]
    });
});

当前（HighCharts 7+）解决方案，不需要覆盖任何方法，是color根据当前烛台点的开盘价和收盘价之间的比较简单地设置交易量点的属性：green if <, red if >,如果相等，则为黄色。

这是一个最小的例子。

// Return a color matching the candle by comparing the open (1) and close (4)
function volumeBarColor(point) {
  if (point[1] < point[4])
    return 'green';
  if (point[1] > point[4])
    return 'red';
  return 'yellow';
}

Highcharts.getJSON('https://www.highcharts.com/samples/data/aapl-ohlcv.json', data => {

  // Split the data set into ohlc and volume
  const ohlc = [],
      volume = [];

  for (let i = 0; i < data.length; i += 1) {
    ohlc.push([
      data[i][0], // the date
      data[i][1], // open
      data[i][2], // high
      data[i][3], // low
      data[i][4], // close
    ]);

    volume.push({
      x: data[i][0], // the date
      y: data[i][5], // the volume
      color: volumeBarColor(data[i]),
    });
  }


  // Create the chart
  Highcharts.stockChart('container', {

    title: {
      text: 'AAPL Historical'
    },

    yAxis: [{
      labels: {
        align: 'right',
        x: -3
      },
      height: '60%',
    }, {
      labels: {
        align: 'right',
        x: -3
      },
      top: '65%',
      height: '35%',
      offset: 0,
    }],

    series: [{
      type: 'candlestick',
      name: 'AAPL',
      data: ohlc,
    }, {
      type: 'column',
      name: 'Volume',
      data: volume,
      yAxis: 1,
    }]
  });
});
