问题描述

  plotOptions：{
列：{
 pointPadding：0.2，
 borderWidth：0，
} 
}，
系列：[{
 name：'Tokyo'，
 data：[49.9 ，0,106.4,129.2,144.0,176.0,135.6,148.5,216.4,194.1,95.6,54.4]，
 
}，{
名称：'纽约'，
数据：[83.6,78.8，null，93.4,106.0,84.5,105.0,104.3,91.2,83.5,106.6,92.3] 
 
}，{
名称：'伦敦'，
数据：[48.9，38.8，39.3，0，47.0，48.3，59.0，59.6，52.4，65.2，59.3，51.2] 
 
}，{

解决方案

您可以让自定义函数负责定位您的列：

  var justifyColumns = function（chart）{
 var categoriesWidth = chart.plotSizeX /（1 + chart.xAxis [0] .max  -  chart.xAxis [0] .min），
 distanceBetweenColumns = 0， 
 each = Highcharts.each，
 sum，categories = chart.xAxis [0] .categories，
 number; 
 for（var i = 0; i< categories.length; i ++）{
 sum = 0; 
 each（chart.series，function（p，k）{
 if（p.visible）{
 each（p.data，function（ob，j）{
 if （ob.category == categories [i]）{
 sum ++; 
} 
}）; 
} 
}）; 
 distanceBetweenColumns = categoriesWidth /（sum + 1）; 
 number = 1; 
 each（chart.series，function（p，k）{
 if（p.visible）{
 each（p.data，function（ob，j）{
 if （ob.category == categories [i]）{
 ob.graphic.element.x.baseVal.value = i * categoriesWidth + distanceBetweenColumns * number  -  ob.pointWidth / 2; 
 number ++; 
} 
}）; 
} 
}）; 
} 
}; 
  

您可以使用chart.plotSizeX等图表参数来计算列之间的距离。

您也可以使用getColumnMetrics函数的包装函数

亲切的问候。

Trying to remove column with zero value from highcharts.

plotOptions: {
        column: {
            pointPadding: 0.2,
            borderWidth: 0,
        }
    },
    series: [{
        name: 'Tokyo',
        data: [49.9, 0, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4],

    }, {
        name: 'New York',
        data: [83.6, 78.8, null, 93.4, 106.0, 84.5, 105.0, 104.3, 91.2, 83.5, 106.6, 92.3]

    }, {
        name: 'London',
        data: [48.9, 38.8, 39.3, 0, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2]

    }, {

    }]

解决方案

You can make custom function responsible for positioning your columns:

var justifyColumns = function(chart) {
  var categoriesWidth = chart.plotSizeX / (1 + chart.xAxis[0].max - chart.xAxis[0].min),
    distanceBetweenColumns = 0,
    each = Highcharts.each,
    sum, categories = chart.xAxis[0].categories,
    number;
  for (var i = 0; i < categories.length; i++) {
    sum = 0;
    each(chart.series, function(p, k) {
      if (p.visible) {
        each(p.data, function(ob, j) {
          if (ob.category == categories[i]) {
            sum++;
          }
        });
      }
    });
    distanceBetweenColumns = categoriesWidth / (sum + 1);
    number = 1;
    each(chart.series, function(p, k) {
      if (p.visible) {
        each(p.data, function(ob, j) {
          if (ob.category == categories[i]) {
            ob.graphic.element.x.baseVal.value = i * categoriesWidth + distanceBetweenColumns * number - ob.pointWidth / 2;
            number++;
          }
        });
      }
    });
  }
};

You can use you chart parameters like chart.plotSizeX for calculating distance between your columns.

Here you can find live example: http://jsfiddle.net/7o0eq05L/8/

You can also use wrapper of getColumnMetrics function
