VisualizaçõesHow to switch out charts on the same canvas with Apache ECharts?
Basically what I'm trying to do is have 5 options of graphs each displaying a different set of data (over the same span of time).
Here's what I have right now - it's almost everything I want, except the dropdown menu makes it look very messy in my opinion, so I wanted to see if anyone knew of a way using Apache ECharts' library functions to integrate it nicely? I've been looking through the docs for a few hours but I don't think anything fits.
If it helps, the function I'm using right now alongside the dropdown menu is something like:
function change_day_chart(value) {
if (value == '0') {
day_chart.setOption(prices, true);
}
if (value == '1') {
day_chart.setOption(buy_volume, true);
}
if (value == '2') {
day_chart.setOption(sell_volume, true);
}
if (value == '3') {
day_chart.setOption(seven_day_buy, true);
}
if (value == '4') {
day_chart.setOption(seven_day_sell, true);
}
}
tl;dr is there any built-in way to switch between datasets in Apache ECharts?

I don’t know your data, but this is my code.
the same chart get different parameters,use filter function to deal.
For your reference.
var respon
$.ajax({
url: 'api/url',
type: 'post',
contentType: 'application/json',
dataType: 'json',
success: function (rets) {
respon = rets;
$('#Select').trigger('change');
//get all data
},
error: function (xhr, ajaxOptions, thrownError) {
console.log(xhr.responseText);
}
});
$('#Select').on('change', function () {
var Qry = $(this).val(); //Select value
var res = respon.filter(item => item.Flag == Qry)
//do something
var option = {
//Omit
};
Chart.setOption(option,true);
});
