1. In the CDE Layout perspective, on the Layout Structure toolbar, click the Add Resource icon.

   

2. In the Add Resource dialog box, enter the following data:

   • For Resource Type, select Javascript.
   • For Resource Source, select External File. Click Ok.
   

3. In the Properties pane, click in the Value column to the right of the Name property and enter addins. Press Tab or Enter.

   

4. Click the caret ('^') button to the right of the Resource file property and navigate to public demoDashboard files. Click Ok.

5. In the Create File dialog box, enter addins and click Ok.

   You have now created the addins.js file, which will contain the JavaScript code to execute within the dashboard components. Note that the name you give to the JS file is how the file itself will be referenced within the dashboard.

6. To enter content in the addins.js file, select the addins resource in the Layout Structure pane. Locate the Resource file property and click the ellipse ('...') button to open the Edit window. Enter the following content for this file:

   define([
     "cdf/AddIn",
     "cdf/Dashboard.Clean",
     "cdf/Logger",
     "cdf/lib/jquery"
   ], function(AddIn, Dashboard, Logger, $) {
     Dashboard.registerGlobalAddIn("Table", "colType", new AddIn({
       name: "customArrow",
       label: "customArrow",
       defaults: {},
       implementation: function(tgt, st, opt) {
         if(typeof st.value !== "number") {
           Logger.warn("customArrow add-in invalid value: " + st.value);
           return;
         }
         var trend = st.value > 0 ? "up" : "down";
         $(tgt).empty()
               .append($('<ul><span class="glyphicon glyphicon-arrow-'
                 + trend +'"></span>&nbsp<span>'+ st.value +'%'+'</span></ul>'));
       }
     }));
   });

   • Lines 2 to 5 specify the dependencies needed for the add-in, which are then registered for use in the function.
   • Line 7 registers the add-in, which is then available to the table component.

7. Press the Save button and then press the Close button.

8. Following steps 2 through 5, add a second JavaScript external resource named title and save a new file named title.js in the public demoDashboard files folder. The dashboard will have a title and a subtitle which are provided by the text components created in Step Five. These components will fetch the displayed value from an object returned by the AMD module defined in the title.js file.

9. To enter content in the title.js file, in the Layout Structure pane select the title resource and then select the Resource file property. Click the ellipse ('...') button to open the Edit window. Enter the following content for this file:

   define(function() {
     return {
       option1: 'CDE Dashboard',
       option2: 'Using a Table with a custom add-in and a CCC Bar Chart',
     };
   });

   In this file, an AMD module is defined which returns an object with two properties. This object will be accessible to the text components, using the same name as the one used for the Name property of the JavaScript external resource, and its properties will be used as the title and subtitle.

10. Press the Save button and then press the Close button.

     "Country", "Population growth per City [%]"
   };
   Class[] columnTypes = new Class[]{
     String.class, Float.class
   };
   TypedTableModel model = new TypedTableModel(columnNames, columnTypes);
   model.addRow(new Object[]{
     new String("Tokyo"), new Float("60")
   });
   model.addRow(new Object[]{
     new String("Nice"), new Float("20")
   });
   model.addRow(new Object[]{
     new String("London"), new Float("-10")
   });
   model.addRow(new Object[]{
     new String("Munich"), new Float("30")
   });
   model.addRow(new Object[]{
     new String("Porto"), new Float("10")
   });
   model.addRow(new Object[]{
     new String("Brasilia"), new Float("10")
   });
   
   return model;

4. Add the following script to the Query property for the tableQuery data source:

   import org.pentaho.reporting.engine.classic.core.util.TypedTableModel;
   String[] columnNames = new String[]{
     "Country", "City", "Population growth per City"
   };
   Class[] columnTypes = new Class[]{
     String.class, String.class, Float.class
   };
   TypedTableModel model = new TypedTableModel(columnNames, columnTypes);
   model.addRow(new Object[]{
     new String("Japan"), new String("Tokyo"), new Float("60")
   });
   model.addRow(new Object[]{
     new String("France"), new String("Nice"), new Float("20")
   });
   model.addRow(new Object[]{
     new String("UK"), new String("London"), new Float("-10")
   });
   model.addRow(new Object[]{
     new String("Germany"), new String("Munich"), new Float("30")
   });
   model.addRow(new Object[]{
     new String("Portugal"), new String("Porto"), new Float("10")
   });
   model.addRow(new Object[]{
     new String("Brazil"), new String("Brasilia"), new Float("10")
   });
   
   return model;

• Create a dashboard using RequireJS

1. Switch to the Components perspective.

2. From the Components list, expand the appropriate Group section, and then add the following components to the dashboard with the specified Name and HtmlObject properties in the table below. (See Customize the Components Perspective for more detailed instruction.)

   Group	Component	Name	HtmlObject
   Others	Text Component	subTitleComponent	subTitleColumnObj
   Others	Text Component	titleComponent	titleColumnObj
   Others	table Component	tableComponent	tableObj
   Charts	CCC Bar Chart	chartComponent	chartObj

   

3. Set the width and height for the chartComponent bar chart.

   • Click in the Value column for the Height property and type 450. Press Tab or Enter.
   • Click in the Value column for the Width property and type 400. Press Tab or Enter.

4. Set the titleComponent text component by adding the following code to the Expression property:

   function f() {
     return "<strong>" + title.option1 + "</strong>";
   }

   This piece of code is returning the content of option1 defined in the title.js file in Step Three.

5. Set the subTitleComponent text component by adding the following code to the Expression property. Note that this code is similar to the previous step, substituting option2 for option1:

   function f() {
     return title.option2;
   }

6. In the tableComponent component, set the Column Types property as follows:

   

   Notice that the third line in the table is using the non-standard customArrow add-in. It is now available because it was registered earlier using the addins.js JavaScript external resource file.

7. Set the Datasource property for the tableComponent to use the tableQuery data source created earlier in Step Four.

8. Set the Datasource property for the chartComponent to use the chartQuery data source created earlier in Step Four.

• Create a dashboard using RequireJS

Procedure

1. On your Desktop, create a folder named Embed to hold the three files we will create and upload to the Pentaho Server in this tutorial:

   • main.html
   • includeDashboards.js
   • styles.css

2. Use a text editor to create a new HTML file and save it as main.html in the Embed folder you just created. Copy the following HTML code to the file:

   <!DOCTYPE html>
   <html>
     <head>
       <meta http-equiv="content-type" content="text/html; charset=utf-8"/>
       <title>Embedding CDE Dashboards with RequireJS</title>
       <link rel="stylesheet" type="text/css" href="../../repo/files/:public:Embed:styles.css"/>
      <script type="text/javascript" src="../../../plugin/pentaho-cdf-dd/api/renderer/cde-embed.js"></script>
     </head>
     <body>
       <div class="headerContainer">
         <header class="header">
           <a class="logo" href="http://www.pentaho.com/">
             <img src="http://www.pentaho.com/sites/all/themes/pentaho_resp/_media/logo-pentaho-new.svg" alt="Pentaho Logo">
           </a>
           <div class="titleHTML">
             <strong>Embedding CDE Dashboards with RequireJS</strong>
           </div>
         </header>
       </div>
       <div class="dashboardContainer">
         <div id="content1"></div>
         <div id="content2"></div>
         <script src="../../repo/files/:public:Embed:includeDashboards.js"></script>
       </div>
     </body>
   </html>

   • Line 7 loads the cde-embed.js resource, which contains all the RequireJS configurations to embed CDE dashboards into the HTML page.
   • Line 20 creates a div which contains two other divs, identified as content1 and content2, in which two instances of the required dashboard class will be rendered.
   • Line 23 loads the includeDashboards.js file, which uses RequireJS to load the demoDashboard CDE dashboard as a JavaScript class. This file creates both instances and associates each one to its respective div and executes its render function.

3. Create the includeDashboards.js file and save it in the Embed folder. Copy the following JS code to the file:

   require([
     "dash!/public/demoDashboard/demoDashboard.wcdf"
   ], function(SampleDash) {
     // Create two instances of the same dashboard that use distinct DOM elements
     (new SampleDash("content1")).render();
     (new SampleDash("content2")).render();
   });

   • The CDE dashboard is obtained via the CDE endpoint, /pentaho/plugin/pentaho-cdf-dd/api/renderer/getDashboard. The path field in the query string must contain the path to the CDE dashboard. Below is an example.

     require([
       "/pentaho/plugin/pentaho-cdf-dd/api/renderer/getDashboard?path=/public/demoDashboard/demoDashboard.wcdf"
     ], function(SampleDash) { /* code */ });

   • This endpoint returns a RequireJS module which contains a class for a specific dashboard which is used to create new dashboard instances. You can also embed a dashboard using the simpler dash! RequireJS loader plugin, such as in the includeDashboards.js source code. Below is an example.

     require([
       "dash!/public/demoDashboard/demoDashboard.wcdf"
     ], function(SampleDash) { /* code */ });

4. Create the styles.css file in the Embed folder. Copy the following CSS code to the file:

   body {
     padding: 10px;
   }
   
   img {
     width: 300px;
     padding-bottom: 10px;
   }

5. Zip the Embed folder, and then use PUC to upload the compressed folder to the Pentaho Server’s Public folder.

6. Finally, review your work. From the Public Embed folder, open the main.html​ file. The embedded dashboard should look similar to the image below.

• Step 2: edit the settings XML files
• Step 3: edit the Pentaho XML file
• Step 4: edit the main HTML file
• Step 5: access the embedded dashboard

Procedure

1. Open the demoDashboard in CDE.

   1. Log on to Pentaho User Console and navigate to the Browse Files perspective.

   2. In the Folders pane, click to expand the Public folder, and then click to highlight the demoDashboard folder.

      

   3. In the Files pane, click on demoDashboard and then, in the File Actions pane, click Edit.

      You are now in the Opened perspective with CDE in editing mode. The Editing:demoDashboard tab is now active in CDE.

2. In the Components perspective, press ShiftG. In the Choose what charts to render as CGG popup, click to select the chartComponent check box.

   This popup lists all the components available to CGG, such as the Community Charting Components (CCC) chart components. When you save the dashboard, CGG generates a JavaScript file for each chart selected in the popup and saves it in your solutions directory.

3. Click the Url button to generate a URL link to CGG which will export the target chart image. Copy the export link by selecting the full URL text and pressing CtrlC on your keyboard. When finished, click Close.

   

4. Before we can use the export URL, we need to save the dashboard so the CGG scripts are generated and saved in the proper repository. To save the dashboard, on the CDE menu bar, click Save.

5. View the generated CGG JavaScript files. In Pentaho User Console, navigate to your demoDashboard folder. Note the following files:

   • The demoDashboard_chartComponent.js contains the chart definitions.
   • The chartComponent.js contains the same content as the above file. This file is saved for backwards compatibility with previous server versions.
   

6. Open a browser window and paste the export URL (from Step 3) into the browser's navigation bar. Press Enter. The chart image displays in the browser window.
