/**
 * Build and configure a multiple axis chart.  A multiple axis chart support more than
 * one range axis.  Multiple datasets using different ranges can be displayed as long as
 * they share a common domain axis.  Each dataset can be rendered differently, so one chart
 * can contain (for example) two line charts, a bar chart and an area chart.
 * <br><br>/*from   www.j av  a  2  s  .  c  om*/
 * Multiple axis charts are handled differently than the other chart types.  They do not
 * have a dataset, as each chart that is added to the multiple axis chart has its own
 * dataset.  For simplicity, each dataset is treated as its own chart, and in fact we
 * reuse the design of all the chart types and let JFreeChart actually run them.  Then
 * we pull out the bits we need and add it to the common chart.  All the plot and chart
 * options on the nested charts is ignored, and all formatting is controlled by the plot
 * attached to the multiAxisChart.  The one exception is seriesColor, which can be used in
 * a nested report to specify a color for a specific series in that report.
