> qcobjects create mynewapp --custom=qcobjects-charts

2.- Now, you can test your new app usign npm test:

npm i --save-dev jasmine && npm test

3.- If everything is ok, you can view your app in a browser by launching with the QCObjects Built-In Server:

qcobjects launch mynewapp

4.- Go to your browser and navigate to https://localhost

Dashboard Tutorial

Placing chart components

Go to templates/components/charts folder and place a new chart template, for css normalising purposes, it is recomended to enclose your template in a

tag:

Here is an example:

<article>
<!-- Your template goes here -->
<style>
        @import url("./css/components/card.css");
        @import url("./css/components/highcharts.css");
</style>

<div class="card">
    <figure class="highcharts-figure">
      <div class="container" id="areachart">
        Loading chart...
      </div>
      <p class="highcharts-description">
          Demonstrating a basic area chart, also known as a mountain chart.
          Area charts are similar to line charts, but commonly used to visualize
          volumes.
      </p>
    </figure>
</div>
<!-- this is the end of your template -->
</article>

Now that you have created the chart template, you can use it on any component you want, just name it as the template. Example: if the name of your template is: basicareachart.tpl.html then the name you have to use it in the component is basicareachart. Name attributes of the components in QCObjects are not unique, so you can use the same name for many components without having issues.

<!--
  As the component template is placed inside a charts subfolder (templates/components/charts)
  Then the name needs to start with "charts/" prefix as a direct reference to the subfolder path
-->
<component name="charts/fc-barcodechart"></component>

The result of this is just inserting the html code of the template templates/components/charts/basicareachart.tpl.html into the component that you have placed in your main html page

NOTE: check out the prebuilt example in templates/components/pages/page1.tpl.html

## Adding behaviour using Controllers

Now you have to add some behaviour to have the new chart loaded into the component and not just dead html tag elements:

First, create a new QCObjects Controller, to do so, go to js/packages/ folder and open the file org.example.mycharts.js to create your custom controllers package:

Here is an example of a Bar Chart by using FusionCharts:

'use strict';
// js/packages/org.example.mycharts.js

'use strict';
Package('org.example.mycharts', [
  Class('BarChartFCController', FCController, {
    done: function() {
      // this is an example to build a bar chart using FusionCharts
      var controller = this;
      this.loadFusionCharts().then(
        function() {
          // Your custom datasource for your chart goes here
          // to get more examples and license using FusionCharts, go to fusioncharts.com

          const dataSource = {
            "chart": {
              "caption": "Countries With Most Oil Reserves [2017-18]",
              "subcaption": "In MMbbl = One Million barrels",
              "yaxisname": "Reserves (MMbbl)",
              "captionalignment": "left",
              "numbersuffix": "K",
              "labeldisplay": "AUTO",
              "theme": "fusion"
            },
            "data": [{
                "label": "Venezuela",
                "value": "290"
              },
              {
                "label": "Saudi",
                "value": "260"
              },
              {
                "label": "Canada",
                "value": "180"
              },
              {
                "label": "Iran",
                "value": "140"
              },
              {
                "label": "Russia",
                "value": "115"
              },
              {
                "label": "UAE",
                "value": "100"
              },
              {
                "label": "US",
                "value": "30"
              },
              {
                "label": "China",
                "value": "30"
              }
            ]
          };

          FusionCharts.ready(function() {
            const myChart = new FusionCharts({
              type: "column2d",
              renderAt: "chart-container",
              width: "100%",
              height: "500",
              dataFormat: "json",
              dataSource
            }).render();
          });

          // this is the end of your code

        });
    }
  })
]);

NOTE: If you want to create separate files, for instance: one for every Class definition, you must to add the corresponding Import line in the org.quickcorp.custom.controllers.js package before for every new package you want to add. It is recomended to use a hierarchy order in your package imports to have a very progressive and quick load of your dependencies.

To use your new BarChartFCController into a component, you only need to set up a value in a controllerClass attribute of a component tag

<component name="charts/fc-barcodechart" controllerClass="BarChartFCController"></component>
