我想创建一个动态图表,以动态方式显示所有条形,除了观察对象的人(在这种情况下:由Afrika,Amerika等人代表的人)。您知道如何做到(以一种简单的方式)?
谢谢!
的高图代码Highcharts.chart('container', {
chart: {
type: 'bar'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: <a href="https://en.wikipedia.org/wiki/World_population">Wikipedia.org</a>'
},
xAxis: {
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 80,
floating: true,
borderWidth: 1,
backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'),
shadow: true
},
credits: {
enabled: false
},
series: [{
name: 'Year 1800',
data: [107, 31, 635, 203, 2]
}]
});
答案 0 :(得分:1)
您只需为数据中的点设置color
:
Highcharts.chart('container', {
series: [{
type: 'bar',
data: [43934, {
y: 52503,
color: 'red'
}, 57177, 69658, 97031, 119931, 137133, 154175]
}]
});
如果要根据某些条件更改颜色,则可以使用update
方法进行定位,例如在load
事件中:
chart: {
events: {
load: function() {
Highcharts.each(this.series[0].points, function(p) {
if (p.y > 8) {
p.update({
color: 'red'
});
}
});
}
}
}
