highcharts用零值删除间隙(列) [英] highcharts remove gap (column) with zero value
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]
},{
名称:'Berlin',

这里是演示

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。
您可以在这里找到现场示例:

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],

Thanks, Vitaliy
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
