D3.js Bubble chart graph doesn't appears with AngularJS


I make a Bubble chart graph with D3.js and I would like to transform it using AngularJS but I am lost... I read this tutorial but anything is appears.

This is the code I make :

var d3DemoApp = angular.module('d3DemoApp', []);

// controller business logic
d3DemoApp.controller('AppCtrl', function AppCtrl ($scope) {

    $scope.data = './data.json';

    $scope.getCommitData = function () {
        $http({
            method: 'GET',
            url: $scope.data
        }).
        success(function (data) {
            // attach this data to the scope
            $scope.data = data;

            // clear the error messages
            $scope.error = '';
        }).
        error(function (data, status) {
            $scope.error = 'Error: ' + status;
        });
    };

    // get the commit data immediately
    $scope.getCommitData();
});

d3DemoApp.directive('ghVisualization', function () {

    return {
        restrict: 'E',
        scope: {
            val: '=',
            grouped: '='
        },
        link: function (scope, element, attrs) {
            var diameter = 900,
                format = d3.format(",d"),
                color = d3.scale.category20c();

            var bubble = d3.layout.pack()
                .sort(null)
                .parameter3([diameter, diameter])
                .value(function(d) { return (d.parameter1+1); })
                .padding(1.5);

            var svg = d3.select("body").append("svg")
                .attr("width", diameter)
                .attr("height", diameter)
                .attr("class", "bubble");

            scope.data = getCommitData();

            var node = svg.selectAll(".node")
                .data(bubble.nodes(classes($scope.data))
                    .filter(function (d) {
                        return !d.children;
                    }))
                .enter().append("g")
                .attr("class", "node")
                .attr("transform", function (d) {
                    return "translate(" + d.x + "," + d.y + ")";
                });

            node.append("title")
                .text(function (d) {
                    return d.className + ": " + format(d.value);
                });

            node.append("circle")
                .attr("r", function (d) {
                    return d.r;
                })
                .style("opacity", "0")
                .style("fill", function (d) {
                    return "red";
                });

            node.append("text")
                .attr("dy", ".3em")
                .style("text-anchor", "middle")
                .text(function (d) {
                    return d.className.substring(0, d.r / 3);
                })
                .style("opacity", "0");

            node.on("click", click);
            function click(d) {
                alert("There is a click");
                document.getElementById('myDiv').value = d.parameter2;

            };


            // Returns a flattened hierarchy containing all leaf nodes under the root.
    function classes(root) {
        var classes = [];
        function recurse(name, node) {
            if (node.children) node.children.forEach(function(child) { recurse(node.name, child); });
           else classes.push({parameter2: name, className: node.name, value: node.parameter3, parameter3: node.parameter3});
        }
        recurse(null, root);
        return {children: classes};
    }
    d3.select(self.frameElement).style("height", diameter + "px");
        }
    }
});

I hope you will can help me because I am very lost... Thanks a lot !


Solution

  • There are lot of missing code

    (i) You have not added ng-app to your view

    (ii) $http was not injected since you are retrieving data

    (iii) directive was not properly declared and data was a not passed!

    Here is the View:

      <div id="containerGraphBubble">
        <bubble-chart chart-data="chartData">
        </bubble-chart>
      </div>
    

    Here is the Directive:

    d3DemoApp.directive('bubbleChart', function() {
      return {
        restrict: 'EA',
        transclude: true,
        scope: {
          chartData: '='
        },
        link: function(scope, elem, attrs) {
    
          scope.$watch('chartData', function(newValue, oldValue) {
            if (newValue) {
              scope.drawChart(newValue);
            }
          });
    
          scope.drawChart = function(rootData) {
            var diameter = 960,
              format = d3.format(",d"),
              color = d3.scale.category20c();
    
            var bubble = d3.layout.pack()
              .sort(null)
              .size([diameter, diameter])
              .value(function(d) {
                console.log(d.size);
                return d.size;
              })
              .padding(1.5);
    
            var svg = d3.select("body").append("svg")
              .attr("width", diameter)
              .attr("height", diameter)
              .attr("class", "bubble");
    
    
    
            var node = svg.selectAll(".node")
              .data(bubble.nodes(classes(rootData))
                .filter(function(d) {
                  return !d.children;
                }))
              .enter().append("g")
              .attr("class", "node")
              .attr("transform", function(d) {
                return "translate(" + d.x + "," + d.y + ")";
              });
    
            node.append("title")
              .text(function(d) {
                return d.className + ": " + format(d.value);
              });
    
            node.append("circle")
              .attr("r", function(d) {
                return d.r;
              })
              .style("fill", function(d) {
                return color(d.size);
              });
    
            node.append("text")
              .attr("dy", ".3em")
              .style("text-anchor", "middle")
              .text(function(d) {
                return d.className.substring(0, d.r / 3);
              });
            // Returns a flattened hierarchy containing all leaf nodes under the root.
            function classes(root) {
              var classes = [];
    
              function recurse(name, node) {
                if (node.children) node.children.forEach(function(child) {
                  recurse(node.name, child);
                });
                else classes.push({
                  packageName: name,
                  className: node.name,
                  value: node.size,
                  size: node.size
                });
              }
              recurse(null, root);
              return {
                children: classes
              };
            }
            d3.select(self.frameElement).style("height", diameter + "px");
          }
    
          if (typeof scope.chartData != "undefined") {
            scope.drawChart(scope.chartData);
          }
    
        }
      };
    });
    

    Here is the working Application
