/**
* Class: $.jqplot.MekkoRenderer
* Draws a Mekko style chart which shows 3 dimensional data on a 2 dimensional graph.
* the <$.jqplot.MekkoAxisRenderer> should be used with mekko charts. The mekko renderer
* overrides the default legend renderer with its own $.jqplot.MekkoLegendRenderer
* which allows more flexibility to specify number of rows and columns in the legend.
*
* Data is specified per bar in the chart. You can specify data as an array of y values, or as
* an array of [label, value] pairs. Note that labels are used only on the first series.
* Labels on subsequent series are ignored:
*
* > bar1 = [['shirts', 8],['hats', 14],['shoes', 6],['gloves', 16],['dolls', 12]];
* > bar2 = [15,6,9,13,6];
* > bar3 = [['grumpy',4],['sneezy',2],['happy',7],['sleepy',9],['doc',7]];
*
* If you want to place labels for each bar under the axis, you use the barLabels option on
* the axes. The bar labels can be styled with the ".jqplot-mekko-barLabel" css class.
*
* > barLabels = ['Mickey Mouse', 'Donald Duck', 'Goofy'];
* > axes:{xaxis:{barLabels:barLabels}}
*
