我有一個包含兩個區域系列的圖表,第二個系列的fillOpacity爲0.01,我想在單擊第一個圖例時更改該系列的fillOpacity。我會怎麼做呢?Highcharts在legendItemClick上更改了一系列填充不透明度
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
marginRight: 130,
marginBottom: 25
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+
this.x +': '+ this.y +'°C';
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
series: [{
name: 'Tokyo',
type: 'area',
events: {
legendItemClick: function() {
chart.series[1].fillOpacity = 0.75;
chart.redraw();
}
},
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
type: 'area',
fillOpacity: '0.01',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
},
{
name: 'New York',
type: 'area',
fillOpacity: '0.01',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}]
});
這完美地工作,謝謝! – JvnD 2013-03-05 23:36:17
