let data = [];
for (let i = 0, min = 5, max = 99; i < 6; i++) {
data.push(Math.floor(Math.random() * (max + 1 - min) + min));
}
that.loading = !that.loading;
that.bar.series[0].data = data;

You need use global variable to register component. (Ref)
So, change IEcharts to "v-chart": VueECharts
For example:
// https://github.com/ecomfe/vue-echarts#using-the-component
var app = new Vue({
el: "#app",
components: {
"v-chart": VueECharts
},
data() {
let data = []
for (let i = 0; i <= 360; i++) {
let t = i / 180 * Math.PI
let r = Math.sin(2 * t) * Math.cos(2 * t)
data.push([r, i])
}
return {
polar: {
title: {
text: 'Demo'
},
legend: {
data: ['line']
},
polar: {
center: ['50%', '54%']
},
tooltip: {
trigger: 'axis',
axisPointer: {
type: 'cross'
}
},
angleAxis: {
type: 'value',
startAngle: 0
},
radiusAxis: {
min: 0
},
series: [
{
coordinateSystem: 'polar',
name: 'line',
type: 'line',
showSymbol: false,
data: data
}
],
animationDuration: 2000
}
}
}
});
