HOWTO: Using the global configuration values

Global configuration values are an easy way to reduce the amount of code on your pages if you're showing multiple charts that you want to all look the same - or at least share some configuration values.

You can set all or just a few values on the global object and all subsequently created chart objects will pick up those values. Here's an example:

    RGraph.SVG.GLOBALS.backgroundGridVlines = false;
    RGraph.SVG.GLOBALS.backgroundGridBorder = false;
    RGraph.SVG.GLOBALS.xaxisLabels          = ['Mon', 'Tue','Wed','Thu','Fri','Sat','Sun'];
    RGraph.SVG.GLOBALS.colors               = ['blue', 'red','pink','green'];
    RGraph.SVG.GLOBALS.marginInner          = 15;
    RGraph.SVG.GLOBALS.xaxis                = false;
    RGraph.SVG.GLOBALS.yaxis                = false;
    new RGraph.SVG.Bar({
        id: 'cc',
        data: [
            [8,8,8,4],[4,1,4,9], [6,3,6,3], [2,8,5,5],
            [4,6,1,2], [6,3,8,6], [4,8,4,8]
        options: {
            marginInnerGrouped: 2

    new RGraph.SVG.Bar({
        id: 'cc2',
        data: [5,8,7,6,4,3,5],
        options: {

The global properties are read and set first - so any further configuration that you then set on the individual object will override the global value.
