PeriodAxis.setFirst() does not work or not documented well

[jdotsoft]

Demo the issue:
Add the line domainAxis.setFirst(new Month(10, 2001)); in the demo PeriodAxisDemo1.java

Expected the chart to start from Oct-2010, but it starts from the first chart point.
Commenting out the method domainAxis.setAutoRangeTimePeriodClass(Month.class); does not have effect.
Using v1.5.5, Java-8

Verify that you invoke setFirst() after calling setDomainAxis().

It works! Please update JavaDoc.

The constructor PeriodAxis(label, first, last) does not work with this required sequence of calls.
BTW, it is very unusual sequence of calls. I expect all settings for PeriodAxis object to be called before finally calling setDomainAxis() with this PeriodAxis object.

From user's perspective classes PeriodAxis and DateAxis are very similar. It would be great to have method DateAxis.setLabelInfo() similar to PeriodAxis.setLabelInfo() and method PeriodAxis.setMinimumDate() and PeriodAxis.setMaximumDate() similar to class DateAxis. Please create feature requests for these methods.

Rather than relying on an existing time series ChartFactory, it might be useful to aggregate the required sequence into a custom factory method.
