javascript - Chart.js stacked and grouped bar chart -

-

is there way stacked , grouped bar chart chart.js library?

it should http://www.highcharts.com/demo/column-stacked-and-grouped

ok, found solution. it's described in github issue , solution in this jsfiddle

chart.defaults.groupablebar = chart.helpers.clone(chart.defaults.bar);  var helpers = chart.helpers; chart.controllers.groupablebar = chart.controllers.bar.extend({   calculatebarx: function (index, datasetindex) {     // position bars based on stack index     var stackindex = this.getmeta().stackindex;     return chart.controllers.bar.prototype.calculatebarx.apply(this, [index, stackindex]);   },    hideotherstacks: function (datasetindex) {     var meta = this.getmeta();     var stackindex = meta.stackindex;      this.hiddens = [];     (var = 0; < datasetindex; i++) {       var dsmeta = this.chart.getdatasetmeta(i);       if (dsmeta.stackindex !== stackindex) {         this.hiddens.push(dsmeta.hidden);         dsmeta.hidden = true;       }     }   },    unhideotherstacks: function (datasetindex) {     var meta = this.getmeta();     var stackindex = meta.stackindex;      (var = 0; < datasetindex; i++) {       var dsmeta = this.chart.getdatasetmeta(i);       if (dsmeta.stackindex !== stackindex) {         dsmeta.hidden = this.hiddens.unshift();       }     }   },    calculatebary: function (index, datasetindex) {     this.hideotherstacks(datasetindex);     var bary = chart.controllers.bar.prototype.calculatebary.apply(this, [index, datasetindex]);     this.unhideotherstacks(datasetindex);     return bary;   },    calculatebarbase: function (datasetindex, index) {     this.hideotherstacks(datasetindex);     var barbase = chart.controllers.bar.prototype.calculatebarbase.apply(this, [datasetindex, index]);     this.unhideotherstacks(datasetindex);     return barbase;   },    getbarcount: function () {     var stacks = [];      // put stack index in dataset meta     chart.helpers.each(this.chart.data.datasets, function (dataset, datasetindex) {       var meta = this.chart.getdatasetmeta(datasetindex);       if (meta.bar && this.chart.isdatasetvisible(datasetindex)) {         var stackindex = stacks.indexof(dataset.stack);         if (stackindex === -1) {           stackindex = stacks.length;           stacks.push(dataset.stack);         }         meta.stackindex = stackindex;       }     }, this);      this.getmeta().stacks = stacks;     return stacks.length;   }, });  var data = {   labels: ["january", "february", "march"],   datasets: [     {       label: "apples",       backgroundcolor: "rgba(99,255,132,0.2)",       data: [20, 10, 30],       stack: 1     },     {       label: "bananas",       backgroundcolor: "rgba(99,132,255,0.2)",       data: [40, 50, 20],       stack: 1     },     {       label: "cookies",       backgroundcolor: "rgba(255,99,132,0.2)",       data: [60, 20, 20],       stack: 1     },     {       label: "apples",       backgroundcolor: "rgba(99,255,132,0.2)",       data: [20, 10, 30],       stack: 2     },     {       label: "bananas",       backgroundcolor: "rgba(99,132,255,0.2)",       data: [40, 50, 20],       stack: 2     },     {       label: "cookies",       backgroundcolor: "rgba(255,99,132,0.2)",       data: [60, 20, 20],       stack: 2     },     {       label: "apples",       backgroundcolor: "rgba(99,255,132,0.2)",       data: [20, 10, 30],       stack: 3     },     {       label: "bananas",       backgroundcolor: "rgba(99,132,255,0.2)",       data: [40, 50, 20],       stack: 3     },     {       label: "cookies",       backgroundcolor: "rgba(255,99,132,0.2)",       data: [60, 20, 20],       stack: 3     },   ] };  var ctx = document.getelementbyid("mychart").getcontext("2d"); new chart(ctx, {   type: 'groupablebar',   data: data,   options: {     legend: {       labels: {         generatelabels: function(chart) {           return chart.defaults.global.legend.labels.generatelabels.apply(this, [chart]).filter(function(item, i){                 return <= 2;           });         }       }     },     scales: {       yaxes: [{         ticks: {           max: 160,         },         stacked: true,       }]     }   } });
