An SVG Bar chart showing the UK inflation rate

This is a copy of a chart that represents the UK monthly inflation rate (these are the real figures). Not good if you have a mortgage - but on the other hand if you're a saver its a good sign! It's using gradients, labelsAbove and a custom font. It also sets the yaxisMax property to 3.5 so the granularity is clearer.

This goes in the documents header:

<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.bar.js"></script>

Put this where you want the chart to show up:

<div style="width: 750px; height: 300px" id="chart-container"></div>

This is the code that generates the chart:

<script>
    // This is the source data

    // This is the source data
    data = {            
        source: [
            {rate: 3.0, label: 'February 2018'},
            {rate: 3.0, label: 'January 2018'},
            {rate: 3.1, label: 'November 2017'},
            {rate: 3.0, label: 'October 2017'},
            {rate: 3.0, label: 'September   2017'},
            {rate: 2.9, label: 'August 2017'},
            {rate: 2.6, label: 'July 2017'},
            {rate: 2.6, label: 'June 2017'},
            {rate: 2.9, label: 'May 2017'},
            {rate: 2.7, label: 'April 2017'},
            {rate: 2.3, label: 'March 2017'},
            {rate: 2.3, label: 'February 2017'}
        ],
        
        // These are for once the data has been extracted and split up from
        // the source
        data:   [],
        labels: []
    };

    // Reverse the data so that the latest figure is on the right
    data.source = RGraph.SVG.arrayReverse(data.source);
    
    
    // Loop through the source data extracting the required parts
    for (var i=0; i<data.source.length; ++i) {
        if (data.source[i]) {
            
            // Extract the data piece from the source data
            data.data[i] = data.source[i].rate;

            // Extract the label from the source data
            data.labels[i] = ((i+1) % 3 === 0 ? data.source[i].label : '');
        }
    }
