我需要在工具提示中进行货币转换,以便它同时显示 R$(巴西雷亚尔)和 US$(美元)。该系列以 R$ 为单位,因此我需要在工具提示格式化程序中进行一些数学运算以显示 US$。但我该怎么做呢?谁能帮我?
这是代码
$(function () {
Highcharts.setOptions({
lang: {
decimalPoint: ',',
thousandsSep: '.'
}
});
$('#container').highcharts({
chart: {
type: 'area'
},
title: {
text: 'Receita líquida consolidada'
},
legend: {
enabled: false
},
xAxis: {
categories: ['2012', '2011', '2010'],
tickmarkPlacement: 'on',
title: {
enabled: false
}
},
yAxis: {
title: {
text: 'Bilhões'
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b> R$ {point.y} Bilhões</b> (US$ {point.y} Bilhões)<br/>',
shared: true
},
plotOptions: {
series: {
fillOpacity: 1
},
area: {
stacking: 'normal',
lineColor: '#384044',
lineWidth: 1,
marker: {
lineWidth: 1,
lineColor: '#384044',
}
}
},
series: [{
name: 'Receita líquida consolidada',
data: [35.5, 32.5, 19.4],
color: '#4fc6e0'
}]
});
});
