Utilizing the chartjs-plugin-datalabels in conjunction with vue-chart.js for customizing data labels on specific charts

I am currently exploring the use of chartjs-plugin-datalabels with specific charts using vue-chartjs. Initially, I decided to unregister the plugin globally from my main.js file since it is automatically registered when imported.

import Chart from 'chart.js';
import ChartDataLabels from 'chartjs-plugin-datalabels';

Chart.defaults.global.plugins.datalabels.display = false;

After this step, I proceeded to add the plugin for a specific chart. However, despite my efforts, no labels are being displayed.

import { Pie } from "vue-chartjs";
import ChartDataLabels from "chartjs-plugin-datalabels";
export default {
    extends: Pie,
    methods: {
        intChart() {
            var _this = this;
            this.renderChart({
                ..........       
            });
        }
    },

    mounted() {
        this.addPlugin(ChartDataLabels);
        this.intChart();
    }
};

Interestingly, if I comment out the following line, the functionality works for all charts:

Chart.defaults.global.plugins.datalabels.display = false;

Do you have any insights on why this setup is not working specifically for certain charts?

Answer №1

To globally deactivate the chartjs-plugin-datalabels, I found that I needed to utilize

Chart.plugins.unregister(ChartDataLabels);

instead of

Chart.defaults.global.plugins.datalabels.display = false;

within my main.js script. After making this change, the addPlugin function started functioning flawlessly.
