This was answered in the RGraph forum today:

[Formerly there was just a link, but here's some sample code instead]

new RGraph.Bar({
    id: 'cvs',
    data: [6,8,6],
    options: {
        colors: ['#888'],
        backgroundColor: 'Gradient(white:purple)',
        backgroundGrid: false,
        marginInner: 80
    }
}).draw();
