I’m using highcharts to create a master-detail chart, could you help me how to add another series type area to the chart? i have used example from official site, but i cant imagine how to add second area to this chart
const priceChart1 = Highcharts.getJSON(
'https://cdn.jsdelivr.net/gh/highcharts/[email protected]/samples/data/usdeur.json',
data => {
let detailChart;
// create the detail chart
function createDetail(masterChart) {
// prepare the detail chart
var detailData = [],
detailStart = data[0][0];
masterChart.series[0].data.forEach(point => {
if (point.x >= detailStart) {
detailData.push(point.y);
}
});
// create a detail chart referenced by a global variable
detailChart = Highcharts.chart('detail-container', {
chart: {
zoomType: "x",

spacingRight: -20,

// make the container smaller and add a second container for the master chart

container.style.position = 'relative';
container.innerHTML += '<div id="detail-container" style="height: 100%"></div><div id="master-container" style="height: 90px; position: absolute; bottom: 0; width: 100%"></div>';

there is example that i used https://www.highcharts.com/demo/dynamic-master-detail
