this is its official instance echarts k diagram instance
there is code in the instance to set up the display of these data, but it doesn"t work
tooltip: {
formatter: function (param) {
param = param[0];
return [
"Date: " + param.name + "<hr size=1 style="margin: 3px 0">",
"Open: " + param.data[0] + "<br/>",
"Close: " + param.data[1] + "<br/>",
"Lowest: " + param.data[2] + "<br/>",
"Highest: " + param.data[3] + "<br/>"
].join("");
}
excuse me, is this data no longer supported by echarts?
Why does it have this code in its official instance?
