In this Angular getting started guide, you'll learn how to use the wijscatterchart in an HTML project using HTML markup, jQuery script, and AngularJS directives.

For more complex samples that have the controller and model in separate files, see Wijmo Charts in the AngularJS Directive Gallery on our web site.

  1. To create a new HTML page in your favorite text editor, add the following code and save the document with an .html extension. Notice that the <HTML> and <body> tags are different from our usual tags.
    • The <HTML> tag is marked as an Angular app with the ng-app directive, in our script, we will specify that it uses Wijmo.
    • The <body> tag is used to define the scope of the Angular controller that we create. You can use another tag such as a <div> for the scope, but for our purposes, we will use the entire body. The ng-controller directive specifies the controller to use within this scope.

    Drop down and copy markup

    Paste in your favorite text editor.
    Copy Code 
    <!DOCTYPE HTML>
<HTML ng-app="MyApp">
<head>
</head>
<body ng-controller="MyController">
</body>
</HTML>
  2. Add links to the dependencies to your HTML page within the <head> tags. Find the latest dependencies in the content delivery network (CDN) file at wijmo cdn. Along with our usual references, we add two script references for Angular that must come after the jQuery references, so they are the last two lines:
    • One is for AngularJS itself.
    • The other is for Wijmo's Angular javascript integration library.

    Drop down and copy references to paste inside the head tags

  3. Within the <head> tags, below the references, add the following script to set the app to use Wijmo, and to create a model and controller.
    • We use a model to specify two data fields that we link to data supplied in the controller.
    • We use a $scope parameter on the controller to control data context for the model
    • We add an optional $locale parameter on the controller.
    • We add two scopes, each with 20 data rows to the list in the controller.
    To see how this is done in jQuery without Angular, see Change Markers.
    Script
    Copy Code 
    <script type="text/javascript">
    var app = angular.module("MyApp", ["wijmo"]);
    //Type class
    function Type(data) {
        this.Weight = data.Weight;
        this.Height = data.Height;
    };
    function MyController($scope, $locale) {
        $scope.Female = [
            new Type({Weight: 161.4, Height: 63.4}), 
            new Type({Weight: 169.0, Height: 58.2}), 
            new Type({Weight: 166.2, Height: 58.6}), 
            new Type({Weight: 159.4, Height: 45.7}),

            new Type({Weight: 168.2, Height: 53.4}), 
            new Type({Weight: 168.9, Height: 69.0}), 
            new Type({Weight: 173.2, Height: 58.4}), 
            new Type({Weight: 174.0, Height: 73.6}),

        ];
        $scope.Male = [
            new Type({Weight: 175.0, Height: 70.2}), 
            new Type({Weight: 174.0, Height: 73.4}), 
            new Type({Weight: 165.1, Height: 70.5}), 
            new Type({Weight: 177.0, Height: 68.9}),

            new Type({Weight: 182.1, Height: 75.7}), 
            new Type({Weight: 179.8, Height: 84.5}), 
            new Type({Weight: 175.3, Height: 87.7}), 
            new Type({Weight: 184.9, Height: 86.4}), 
            new Type({Weight: 177.3, Height: 73.2}), 
            new Type({Weight: 167.4, Height: 53.9}), 
            new Type({Weight: 178.1, Height: 72.0}),

            new Type({Weight: 188.0, Height: 87.3})
        ];
    }
</script>
  4. Add the following markup within the <body> tags to create the widget.
    • We use a <wij-wijscatterchart> directive to create the widget, and set the height and width options as attributes within the element.
    • We use nested elements in the markup to set the axis, header, legend, and seriesList options.
      • Inside our axis directive, we nest the y axis, and set the text option.
      • We set the header text to show the title for the chart.
      • We set the visible attribute of the legend directive to true to show the legend.
      • Inside our series-list directive, we nest two series objects, one with the data-source directive set to "Female" and the other "Male" and set the marker-type attributes to different shapes for each.
      • Inside each of our series objects, we nest a data directive with nested x and y options that bind to the data fields in the model.
    Markup
    Copy Code 
    <wij-scatterchart height="400" width="600">
    <axis>
        <y text="Total Hardware"></y>
    </axis>
    <header text="Height Versus Weight of 40 Individuals by Gender"></header>
    <legend visible="true"></legend>
    <series-list>
        <series label="Female" data-source="Female" marker-type="box">
            <data>
                <x bind="Weight"></x>
                <y bind="Height"></y>
            </data>
        </series>
        <series label="Male" data-source="Male" marker-type="diamond">
            <data>
                <x bind="Weight"></x>
                <y bind="Height"></y>
            </data>
        </series>
    </series-list>
</wij-scatterchart>
  5. Save your HTML file and open it in a browser. The widget appears like the following live widget.
    MISSING WIDGET TYPE: The "Live Widget" Widget Type could not be found. The "Live Widget" Widget Type may have been deleted since this Widget was created.
