我图表上的标签显示在工具提示上方,看起来不太好。我试着玩zIndex
,但没有结果。如何使工具提示不透明?这是我的 jsFiddle: http: //www.jsfiddle.net/4scfH/3/
$(function() {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'graf1',
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false
},
title: {
margin: 40,
text: 'Podíl všech potřeb'
},
tooltip: {
//pointFormat: '<b>{point.y} Kč [{point.percentage}%]</b>',
percentageDecimals: 2,
backgroundColor: "rgba(255,255,255,1)",
formatter: function() {
return this.point.name + '<br />' + '<b>' + Highcharts.numberFormat(this.y).replace(",", " ") + ' Kč [' + Highcharts.numberFormat(this.percentage, 2) + '%]</b>';
}
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
color: '#000000',
connectorWidth: 2,
useHTML: true,
formatter: function() {
return '<span style="color:' + this.point.color + '"><b>' + this.point.name + '</b></span>';
}
}
}
},
