i not find more relevant on github or anywhere else! if find something, please update same here.

anyway, tried create small heatmap using external file, hope helps!

var myapp = angular.module('myapp', []);    myapp    .controller('heatmapctrl', function($scope) {        //random data      var points = [];      var max = 0;      var width = 840;      var height = 400;      var len = 200;        while (len--) {        var val = math.floor(math.random() * 100);        max = math.max(max, val);        var point = {          x: math.floor(math.random() * width),          y: math.floor(math.random() * height),          value: val        };        points.push(point);      }      // heatmap data format      $scope.heat_data = {        max: max,        data: points      };    })    .directive('heatmap', function() {      return {        restrict: 'e',        scope: {          data: '='        },        template: '<div container></div>',        link: function(scope, ele, attr) {          scope.heatmapinstance = h337.create({            container: ele.find('div')[0]          });          scope.heatmapinstance.setdata(scope.data);        }        };    });
heat-map {    width: 600px;    height: 300px;    display: block;  }    heat-map div {    height: 100%;  }
<script src="https://www.patrick-wied.at/static/heatmapjs/assets/js/heatmap.min.js"></script>  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.1/angular.min.js"></script>  <div ng-app="myapp">    <div ng-controller="heatmapctrl">      <heat-map data="heat_data"></heat-map>    </div>  </div>

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
