        %h3
          %a( href="#setup" ) 1. Setup
        %p Download the latest version here:
        %ul
          %li <a href="https://github.com/c3js/c3/releases/latest" target="_blank">https://github.com/c3js/c3/releases/latest</a>
        %p Installing by Bower/Component is also available with the name <span class="code">c3</span>.

        %p Then, load the scripts and css:

        .sourcecode.highlight
          %pre
            %code.html.xml
              :preserve
                <span class="comment">&lt;!-- Load c3.css --&gt;</span>
                <span class="tag">&lt;<span class="title">link</span> <span class="attribute">href</span>=<span class="value">"/path/to/c3.css"</span> <span class="attribute">rel</span>=<span class="value">"stylesheet"</span>&gt;</span>

                <span class="comment">&lt;!-- Load d3.js and c3.js --&gt;</span>
                <span class="tag">&lt;<span class="title">script</span> <span class="attribute">src</span>=<span class="value">"/path/to/d3.v5.min.js"</span> <span class="attribute">charset</span>=<span class="value">"utf-8"</span>&gt;</span><span class="tag">&lt;/<span class="title">script</span>&gt;</span>

      %section
        %h3
          %a( href="#generate" ) 2. Generate Chart
        %p C3 generates a chart by calling <span class="code">generate()</span> with the argument object, and an element including the chart will insert into the element specified as a selector in that argument as <span class="code">bindto</span>.

        %p Prepare the element to bind the chart:
        .sourcecode.highlight
          %pre
            %code.html.xml
              :preserve
                <span class="tag">&lt;<span class="title">div</span> <span class="attribute">id</span>=<span class="value">"chart"</span>&gt;&lt;/<span class="title">div</span>&gt;</span>

        %p And, call <span class="code">generate()</span> with arguments:

        .sourcecode.highlight
          %pre
            %code.javascript
              :preserve
                var chart = c3.generate({
                    bindto: '#chart',
                    data: {
                      columns: [
                        ['data1', 30, 200, 100, 400, 150, 250],
                        ['data2', 50, 20, 10, 40, 15, 25]
                      ]
                    }
                });

        %p C3 supports the asynchronous module definition (AMD) API. If you use <a href="http://requirejs.org/" target="_blank">RequireJS</a>, you can load like this:

        .sourcecode.highlight
          %pre
            %code.javascript
              :preserve
                require.config({
                  baseUrl: '/js',
                  paths: {
                    d3: "http://d3js.org/d3.v5.min"
                  }
                });

                require(["d3", "c3"], function(d3, c3) {
                  c3.generate({
                    ...
                  });
                });

        %p Then, you will see the chart:

        #chart2_1
        %br

        %p Data can be loaded as <a href="/samples/data_columned.html">columned data</a> / <a href="/samples/data_rowed.html">rowed data</a> / <a href="/samples/data_url.html">csv in URL</a>.
        %p There are serveral options to customize the chart and you can see those here:
        %ul
          %li <a href="/examples.html">Examples</a>

      %hr

      %section
        %h3
          %a( href="#customize" ) 3. Customize Chart
        %p The chart can be customize by giving some options when generating. We will introduce some of them here.

        %h4 1. Additional Axis
        %p Introduce additional axis for <span class="code">data2</span>. Add <span class="code">data.axes</span> and <span class="code">axis.y2.show</span> as follows:

        .sourcecode.highlight
          %pre
            %code.javascript
              :preserve
                var chart = c3.generate({
                    bindto: '#chart',
                    data: {
                      columns: [
                        ['data1', 30, 200, 100, 400, 150, 250],
                        ['data2', 50, 20, 10, 40, 15, 25]
                      ],
                      axes: {
                        data2: 'y2' // ADD
                      }
                    },
                    axis: {
                      y2: {
                        show: true // ADD
                      }
                    }
                });

        %p Then, the chart will be like this:

        #chart3_1
        %br

        %h4 2. Show Axis Label
        %p Show labels for each axis. Add <span class="code">axis.y.label</span> and <span class="code">axis.y2.label</span> as follows:

        .sourcecode.highlight
          %pre
            %code.javascript
              :preserve
                var chart = c3.generate({
                    bindto: '#chart',
                    data: {
                      columns: [
                        ['data1', 30, 200, 100, 400, 150, 250],
                        ['data2', 50, 20, 10, 40, 15, 25]
                      ],
                      axes: {
                        data2: 'y2'
                      }
                    },
                    axis: {
                      y: {
                        label: { // ADD
                          text: 'Y Label',
                          position: 'outer-middle'
                        }
                      },
                      y2: {
                        show: true,
                        label: { // ADD
                          text: 'Y2 Label',
                          position: 'outer-middle'
                        }
                      }
                    }
                });

        %p Then, the chart will be like this:

        #chart3_2
        %br

        %h4 3. Change Chart Type
        %p Show <span class="code">data2</span> as Bar chart. Add <span class="code">data.types</span> as follows:

        .sourcecode.highlight
          %pre
            %code.javascript
              :preserve
                var chart = c3.generate({
                    bindto: '#chart',
                    data: {
                      columns: [
                        ['data1', 30, 200, 100, 400, 150, 250],
                        ['data2', 50, 20, 10, 40, 15, 25]
                      ],
                      axes: {
                        data2: 'y2'
                      },
                      types: {
                        data2: 'bar' // ADD
                      }
                    },
                    axis: {
                      y: {
                        label: {
                          text: 'Y Label',
                          position: 'outer-middle'
                        }
                      },
                      y2: {
                        show: true,
                        label: {
                          text: 'Y2 Label',
                          position: 'outer-middle'
                        }
                      }
                    }
                });

        %p Then, the chart will be like this:

        #chart3_3
        %br

        %h4 4. Format values
        %p Format the values of each data. Add <span class="code">axis.y.tick.format</span> as follows:

        .sourcecode.highlight
          %pre
            %code.javascript
              :preserve
                var chart = c3.generate({
                    bindto: '#chart',
                    data: {
                      columns: [
                        ['data1', 30, 200, 100, 400, 150, 250],
                        ['data2', 50, 20, 10, 40, 15, 25]
                      ],
                      axes: {
                        data2: 'y2'
                      },
                      types: {
                        data2: 'bar'
                      }
                    },
                    axis: {
                      y: {
                        label: {
                          text: 'Y Label',
                          position: 'outer-middle'
                        },
                        tick: {
                          format: d3.format("$,") // ADD
                        }
                      },
                      y2: {
                        show: true,
                        label: {
                          text: 'Y2 Label',
                          position: 'outer-middle'
                        }
                      }
                    }
                });

        %p Then, the chart will be like this:

        #chart3_4
        %br

        %p More information about the options, please see <a href="/examples.html">Examples</a>. (We'll add the reference soon)

      %hr

      %section
        %h3
          %a( href="#api" ) 4. Use APIs
        %p By using APIs, you can update the chart after it's been rendered. We will introduce some of APIs here. APIs can be called through the object returned from <span class="code">generate()</span>.

        %h4 1. Load Data
        %p By using <span class="code">load()</span> API, you can load data and update the chart dynamically as follows:

        .sourcecode.highlight
          %pre
            %code.javascript
              :preserve
                // var chart = c3.generate({ ... });

                chart.load({
                  columns: [
                    ['data1', 300, 100, 250, 150, 300, 150, 500],
                    ['data2', 100, 200, 150, 50, 100, 250]
                  ]
                });

        %p If you push the button "Load" below, this code will run and the chart will be updated.

        %button.small( onclick="example4_1();" ) Load

        #chart4_1
        %br

        %h4 2. Unload Data
        %p By using <span class="code">unload()</span> API, you can unload the data dynamically as follows:

        .sourcecode.highlight
          %pre
            %code.javascript
              :preserve
                // var chart = c3.generate({ ... });

                chart.unload({
                    ids: ['data2', 'data3']
                });

        %p If you push the button "Unload" below, this code will run and the chart will be updated.

        %button.small( onclick="example4_2();" ) Unload

        #chart4_2
        %br

        %p Please use <span class="code">unload</span> param in <span class="code">load()</span> API if load and unload need to run simultaneously. Please see <a href="/samples/data_load.html">this example</a>.

        %h4 3. Show/Hide Data
        %p By using <span class="code">show()</span> and <span class="code">hide()</span> API, you can show/hide the data dynamically as follows:

        .sourcecode.highlight
          %pre
            %code.javascript
              :preserve
                // var chart = c3.generate({ ... });

                chart.hide(['data2', 'data3']);
                chart.show(['data2', 'data3']);

        %p If you push the button "Show" and "Hide" below, this code will run and the chart will be updated.

        %button.small( onclick="example4_3_2();" ) Hide
        %button.small( onclick="example4_3_1();" ) Show

        #chart4_3
        %br

        %p The documentation about APIs is poor now, so please check the <a href="https://github.com/c3js/c3/issues?state=open">issues on github</a>. There might be some hints about what you want to do. (We will add the document soon)

      %hr

      %section
        %h3
          %a( href="#style" ) 5. Customize Style
        %p C3 give some classes for each element when generating. So, you can change the style of the elements by using those classes.
        %h4 1. Line style
        %p The lines have <span class="code">c3-line-[id]</span> class, so this class can be used to define the style in css as follows:

        .sourcecode.highlight
          %pre
            %code.css
              :preserve
                #chart .c3-line-data2 {
                  stroke-width: 5px;
                }

        #chart5_1
        %br

        %p Please check the class for each element if you want to change the style. Web Inspector would be useful. (We will add the document for class definition soon)

      %hr

      %section
        %h3
          %a( href="#more" ) 6. And More..
        %p Please check the <a href="/examples.html">examples</a> and the <a href="https://github.com/c3js/c3/issues?state=open">issues</a> on github for more information. Sorry for the poor documentation. We're working on now and please give me some time. Thank you.
