chartjs-plugin-custom-legend v1.0.2

chartjs-plugin-custom-legend

This is a plugin for replacing chartjs legend to images.

here, the legend items are images

they change by click/hover you need to pass the images to each dataset. as you can see I also added margin between the legend to the chart

let's see the code:

import {LegendHover, LegendClick, LegendBottomMargin} from "chartjs-plugin-custom-legend"
import { Chart as ChartJS, Legend } from "chart.js";

ChartJS.register(
LegendClick,
LegendHover,
LegendBottomMargin(20),
Legend,
///...rest of the chart plugins
);

const dataset = {
     label:"some label text",
     data:[{y: 50, x: new Date()}],
     // now here we give each dataset its legend item image
     
     // the initial image, mostly you put the same image as the primaryImage
     pointStyle: primaryIMAGE

     //the image in its regular state.
     primaryImage: primaryIMAGE

     // the image in its selected state.
     selectedImage: selectedIMAGE

     // this is a must to track the latest image which is the primary image at initial.  
     lastImage: primaryIMAGE

     // required only if you use hover plugin.
     primaryHoverImage:  primaryHoverIMAGE
     selectedHoverImage: SelectedHoverIMAGE
}

// now only render the chart.
const BarChart = () => {
    return <Bar options={{//whatever your options are...}} data={{datasets:[dataset]}} />;
};



export default BarChart;
