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:
<script>
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: {
marginInner:15,
marginInnerGrouped: 2
}
}).draw();
new RGraph.SVG.Bar({
id: 'cc2',
data: [5,8,7,6,4,3,5],
options: {
}
}).draw();
</script>
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.
