* 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.
*
* 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.
