Building a chart with multiple series types

So far we have learned about the line, columns, and pie series types. It's time to bring all these different series presentations into a single chart. In this section, we use the annual data from 2008 through 2011 to plot three different kinds of series type—column, line, and pie. The column type represents the yearly number of games sold for each type of gaming console. The pie series shows the annual number of gaming consoles sold for each vendor. The last one is the spline series type that discloses how many new game titles there are in total for all the consoles released each year.

In order to enforce the whole graph to use the same color scheme for each type of gaming console, we have to manually assign a color code for each data point in the pie charts and the columns series:

    var wiiColor = '#BBBBBB';
    var x360Color = '#89A54E';
    var ps3Color = '#4572A7';
    var splineColor = '#FF66CC';

We then decorate the chart in a more funky...
