Usage

After installing, import the VueFunnelGraph component:

import "vue3-funnel-graph-js/dist/style.css";
import { VueFunnelGraph } from "vue3-funnel-graph-js";

You can now use the custom element:

<vue-funnel-graph
  :width="width"
  :height="height" 
  :labels="labels"
  :values="values" 
  :colors="colors" 
  :sub-labels="subLabels" 
  :direction="direction"
  :gradient-direction="gradientDirection"
  :animated="true"
  :display-percentage="true"
></vue-funnel-graph>

The values are passed to props:

export default {
  name: 'app',
  components: {
      VueFunnelGraph
  },
  data() {
      return {
          labels: ['Impressions', 'Add To Cart', 'Buy'],
          subLabels: ['Direct', 'Social Media', 'Ads'],
          values: [
          // with the given Labels and SubLabels here's what the values represent:
          // 
          // Direct, Social, Ads  
          //    |      |     |  
          //    v      v     v
              [3000, 2500, 6500], // Segments of "Impressions" from top to bottom
              [3000, 1700, 1000], // Segments of "Add To Cart"
              [600,  200,  130]   // Segments of "Buy"
          ],
          colors: [
              ['#FFB178', '#FF3C8E'], // color set for "Impressions" segment
              ['#A0BBFF', '#EC77FF'], // color set for "Add To Cart" segment
              ['#A0F9FF', '#7795FF']  // color set for "Buy" segment
          ],
          direction: 'horizontal',
          gradientDirection: 'horizontal',
          height: 300,
          width: 800
      };
  }
}
