I developed an angular application with three synchronized line charts (let's assume this is a very helpful example: https://apexcharts.com/angular-chart-demos/line-charts/syncing-charts/).
Now, I cannot find a way to use the toolbar export functionality for all three charts at the same time. I mean: if I click the export PNG button, it exports just one of the three charts. Is it possible to have a kind of "general" export functionality that involves all the charts belonging to the same chart group?
I think the only option is to add a custom menu icon that will download all of them https://apexcharts.com/docs/options/chart/toolbar/#customIcons
And for click method
click: async () => {
let ids = ['chart1', 'chart2'] // you can't select chart by group so we need all ids
for await (let id of ids) {
let dataURI = await ApexCharts.exec(id, 'dataURI')
fetch(dataURI.imgURI).then(res => res.blob()).then(res2 => {
let url = URL.createObjectURL(res2)
let a = document.createElement("a");
a.href = url
a.download=`${id}.png`
a.click();
})
}
}
