Configuring your Chart using PHP

FusionCharts Suite XT includes advanced features that let you add more context to your chart and make data visualization simpler. These features include chart updates, annotations, trend-lines, and events.

This article focuses on how you can configure chart components to:

Update Chart Data

A chart, configured to update data values dynamically, is shown below (click Update Chart Data to start):

{
    "chart": {
        "caption": "Customer Satisfaction Score",
        "subcaption": "Los Angeles Topanga",
        "plotToolText": "Current Score: $value",
        "theme": "fusion",
        "chartBottomMargin": "50",
        "showValue": "1"
    },
    "colorRange": {
        "color": [
            {
                "minValue": "0",
                "maxValue": "90",
                "code": "#e44a00"
            },
            {
                "minValue": "90",
                "maxValue": "150",
                "code": "#f8bd19"
            },
            {
                "minValue": "150",
                "maxValue": "250",
                "code": "#6baa01"
            }
        ]
    },
    "dials": {
        "dial": [
            {
                "value": "70",
                "id": "dial1"
            }
        ]
    }
}

The full code of the above sample is given below:

            }
        }";
        // chart object
        $Chart = new FusionCharts("angulargauge", "angulargauge-1" ,"450", "250", "angulargauge-container", "json", $gaugeData);
        // Render the chart
        $Chart->render();
?>
    <h3>Update data at runtime</h3>
    <div id="angulargauge-container">Chart will render here!</div>
    <div>
        <label for="dial-val">Input dial value</label>
        <input name="dial-val" id="dial-val" type="number" />
        <input type="button" name="update dial" value="Update Dial" onclick="updateData()" />
    </div>
</body>
</html>

The above chart has been rendered using the following steps:

  1. Include the fusioncharts.php file which contains functions to embed the charts.

  2. Include the necessary libraries and components using <script> tags. For example, fusioncharts.js, fusioncharts.theme.fusion.js.

  3. Add the updateData() function to randomly update the value of the chart when the button is clicked.

  4. Store the chart data in a JSON object.

  5. Store the chart configuration in a JSON object. In the JSON object:

    • Set the chart type as column2d. Find the complete list of chart types with their respective alias here.
    • Set the width and height of the chart in pixels.
    • Set the dataFormat as JSON.
    • Embed the json data as the value of dataSource.
  6. Create the <div> elements to:

    • Render the chart using chart id.
    • Create button for updateData().

When you change the values of id and renderAt, ensure that the corresponding changes are reflected in the HTML template. The string values for renderAt in the code, and the corresponding div id in the HTML template, should be the exact same.

Update Chart Attributes

A chart, configured to update the chart caption, sub-caption alignment and chart background dynamically, is shown below (click any one of the buttons shown below the chart to change the chart background and caption, sub-caption alignment):

        },
        {
            "label": "Canada",
            "value": "180"

        {
            "label": "Iran",
            "value": "140"
        },
        {
            "label": "Russia",
            "value": "115"
        },
        {
            "label": "UAE",
            "value": "100"
        },
        {
            "label": "US",
            "value": "30"
        },
        {
            "label": "China",
            "value": "30"
        }
    ]
}

  5. Return the output of the render function (defined in FusionCharts):

    • Pass the request, which is also the only argument accepted by the chart function you are defining.
    • Pass the relative path of the HTML template, where the chart will be rendered.
    • Pass a dictionary.
