I use vue js and I display a graph with chartjs. When I click on the graph I want emit an event for get data in parent component. My onClick function works but not the event. Do you have an idea of my problem ? Component Line2.vue
<script>
import { mixins, Line } from "vue-chartjs";
const { reactiveProp } = mixins;
export default {
extends: Line,
mixins: [reactiveProp],
props: ["options"],
mounted() {
const self = this;
console.log(self);
this.options.onClick = function (e, tooltipItems) {
console.log(tooltipItems[0].__ob__); //.logged
self.$emit("sendIndex", tooltipItems[0]._index);
};
this.renderChart(this.chartData, this.options);
},
};
</script>
<style scoped></style>
My main component
...
<h1 v-on:sendIndex="getIndexCoord($event)">{{ indexCoord }}</h1>
...
methods: {
getIndexCoord: function (e) {
console.log("rrr", e); //Not logged
this.indexCoord = e;
},
}

1.first you create EventBus.js file import Vue from 'vue';
export const EventBus = new Vue();
2.In your char.js file code like below
import { EventBus } from "../EventBus.js";
import { mixins, Line } from "vue-chartjs";
const { reactiveProp } = mixins;
export default {
extends: Line,
mixins: [reactiveProp],
props: ["options"],
mounted() {
const self = this;
console.log(self);
this.options.onClick = function (e, tooltipItems) {
console.log(tooltipItems[0].__ob__); //.logged
EventBus.$emit("sendIndex", tooltipItems[0]._index);
};
this.renderChart(this.chartData, this.options);
},
};
where you want to access your data in that file like below
import { EventBus } from "../EventBus.js";
mounted() {
EventBus.$on('sendIndex', data => {
console.log(data)
});
},
