javascript - display vertical axis label in line chart using chart.js -

-

how add vertical axis (y-axis) label line graph created using chart.js , angular-chart.js

i need display y-axis label. 

html <ion-content ng-controller="agecontroller"> <canvas id="line" class="chart chart-line" data="data"   labels="labels" legend="true" series="series"   click="onclick" colours="['red','yellow']" width="402" height="201" style="width: 402px; height: 201px"> </canvas>  </ion-content>  js  app.controller('agecontroller', ['$scope','$http',function($scope,$http) {                  $scope.labels = ["january", "february", "march", "april", "may", "june", "july"];   $scope.series = ['series a', 'series b'];   $scope.data = [     [65, 59, 80, 81, 56, 55, 40],     [28, 48, 40, 19, 86, 27, 90]   ];                   }]);

the original opinion on axis title outside of canvas (see here https://github.com/nnnick/chart.js/issues/114), given activity on linked issue https://github.com/nnnick/chart.js/issues/52 change.

adding y axis title

that said, here's how can on current version using canvas. first, extend chart draw axis title (mostly rehash how set chartjs y axis title cleaner code)

chart.types.line.extend({     name: "linealt",     initialize: function (data) {         // making space title increasing y axis label width         if (this.options.yaxislabel)             this.options.scalelabel = '         ' + this.options.scalelabel;          chart.types.line.prototype.initialize.apply(this, arguments);          if (this.options.yaxislabel)             this.scale.yaxislabel = this.options.yaxislabel;     },     draw: function () {         chart.types.line.prototype.draw.apply(this, arguments);          // drawing title         if (this.scale.yaxislabel) {             var ctx = this.chart.ctx;             ctx.save();             // text alignment , color             ctx.textalign = "center";             ctx.textbaseline = "bottom";             ctx.fillstyle = this.options.scalefontcolor;             // position             var x = this.scale.xscalepaddingleft * 0.2;             var y = this.chart.height / 2;             // change origin             ctx.translate(x, y)             // rotate text             ctx.rotate(-90 * math.pi / 180);             ctx.filltext(this.scale.yaxislabel, 0, 0);             ctx.restore();         }     } });

from directives, assume using http://jtblin.github.io/angular-chart.js/. if register new chart type so

angular.module('chart.js')     .directive('chartlinealt', ['chartjsfactory', function (chartjsfactory) { return new chartjsfactory('linealt'); }]);

and pass in axis title using options so

... $scope.options = {     yaxislabel: "my y axis label", }

with markup

<canvas id="line" class="chart chart-line-alt" data="data"         labels="labels" legend="true" series="series" options="options"         click="onclick" colours="['red','yellow']" width="402" height="201" style="width: 402px; height: 201px"></canvas>

note added options , changed class chart-line-alt
