URL: https://github.com/apache/echarts/issues/15256#issuecomment-871060690
I added .esm file to my project. I'm getting below errors in console
**this.echartsInstance is undefined
this.echartsInstance.getModel() is undefined**
Here is my ts code
-----------------------------------------
import { EChartOption } from 'echarts';
import L from 'leaflet';
import '../../dist/echarts-extension-leaflet.esm.js';
echartsInstance: any;
option: EChartOption = {};
ngAfterViewInit(): void {
this.setOptions();
}
setOptions() {
this.option = {
leaflet: {
roam: true,
center: [4.9,-1.766667],
zoom: 2,
// the following options are from this plugin
// whether the chart should always re-render when moving/zooming the
map
renderOnMoving: true,
// whether to enable large mode (it's better to enable when data is
large)
largeMode: false,
},
series: [
this.getData()
]
};
}
initMap() {
// get leaflet instance
var map =
this.echartsInstance.getModel().getComponent("leaflet").getMap();
var southWest = L.latLng(-89.98155760646617, -180),
northEast = L.latLng(89.99346179538875, 180);
var bounds = L.latLngBounds(southWest, northEast);
// set max bounds
map.setMaxBounds(bounds);
L.tileLayer('assets/tiles/{z}/{x}/{y}.jpg', {
minZoom: 2,
MaxZoom: 6,
attribution: ''
}).addTo(map);
}
onChartInit(echarts: any) {
this.echartsInstance = echarts;
this.setOptions();
this.initMap();
this.resizeChart();
}
resizeChart() {
if (this.echartsInstance) {
this.echartsInstance.resize();
}
}
And here is my template code
-----------------------------------------
<div echarts
[options]="option"
(chartInit)="onChartInit($event)">
</div>
Can you please help me to figure out why it says instance is undefined?
