i created chartjs plugin waterfall charts.

see https://github.com/martindawson/chartjs-plugin-waterfall

this plugin works checking if of datasets contain property called dummystack set true. stack property must used in conjunction dummystack plugin work properly. if dummystack true hides label, tooltip , sets color invisible. when use stacking creates affect of floating bar shown in image above can use waterfall charts chartjs-2 doesn't support waterfall charts default.

import waterfallplugin 'chartjs-plugin-waterfall';  var chart = new chart(ctx, {     plugins: [waterfallplugin] });  const data = {   datasets: [     {       label: 'closing costs',       data: [50],       backgroundcolor: '#e8cdd7',       stack: 'stack 1',     },     {       label: 'purchase price',       data: [700],       backgroundcolor: '#d29baf',       stack: 'stack 1',     },     {       data: [200],       dummystack: true,       stack: 'stack 2',     },     {       label: 'opening loan balance',       data: [550],       backgroundcolor: '#bb6987',       stack: 'stack 2',     },     {       label: 'initial cash investment',       data: [200],       backgroundcolor: '#a53860',       stack: 'stack 3',     },   ], };
