Add support for null values

[GoogleCodeExporter]

Support for null values should be added such as line or bar charts should not 
be rendered for these.

Using Double.MAX_VALUE for NULL values breaks the XYSeries.getMaxY().  

An easy fix might be to add a check for this NULL value in the updateRange(x,y) 
method before doing mMaxY = Math.max(mMaxY, y);
