An SVG Bar/HBar combo chart

She founded Bet365 - an online gambling firm. Who would have guessed that gambling could be so profitable?! Ok perhaps everyone in the world! Personally though, if a company that I started earned just (?) five million pounds - I'd retire!

The chart itself is quite straightforward with a single solid color for the bars, a small marginInner setting and large text. Being like this though makes the clarity of the chart quite good.

It also uses the labelsAbove setting to show the exact figures that the bars represent.

For smaller screens, the chart is switched from being a Bar chart to a Horizontal Bar chart. There's another, canvas example of this in the download archive called bar-hbar-responsive.html

This goes in the documents header:

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

Put this where you want the chart to show up:

<div style="float: right">
    <div style="width: 600px; height: 250px;" id="chart-container1"></div>
    <div style="width: 350px; height: 650px;" id="chart-container2"></div>
</div>

This is the code that generates the chart - it should be placed AFTER the div tag:

<script>

    //
    // These are used by both charts
    //
    data   = [6,5,13,30,54,199,220,320,469,300];
    labels = ['2012','2013','2014','2015','2016','2017','2018','2019','2020','2021'];

    //
    // These functions are called to draw the charts. Both
    // charts are drawn straight-away but each is alternatively
    // hidden based on the size of the screen.
    //
    drawBar();
    drawHbar();


    //
    // This function draws the Bar chart
    //
    function drawBar()
    {
        new RGraph.SVG.Bar({
            id: 'chart-container1',
            data: data,
            options: {

                // Add labelsAbove and color them turquoise like the bar color
                labelsAbove: true,
                labelsAboveSize: 12,
                labelsAboveColor: '#1280A1',
                labelsAboveBold: true,

                // Give the bars a turqoise color
                colors: ['#1280A1'],
                
                // Only horizontal grid lines are shown
                backgroundGridBorder: false,
                backgroundGridVlines: false,
                
                // Disable both of the X and Y axes (but there are still some
                // X-axis labels given)

                // Give the Y-axis labels some units that are both prepended
                // and appended to the numbers
