Chart Newbie question

[Marty]

I am working on my first Google Charts app.  I am accessing the charts from Java and I am having problems finding the API documentation.  I have been looking around, I can find some Javascript docs, but no Javadoc for the API.  The only javadoc I could find was from 2008, and it did not mention the ComboChart (which is what I am using).  I have also run the chart wizard which gave me the opportunity to tune the chart on the fly, but the data output is also javascript and has options formatted like the following:

 var options = {

          chf: 'bg,lg,100,EFEFEF,0,00FF00,1',

          chxl: '0:|0|1|2|3|4|5|1:|0|50|100|2:|min|average|max',

          chxp: '2,10,50.83,90',

          chxr: '0,1,31',

          chxs: '1,676767,11.5,0,lt,676767',

          chxtc: '',

          chxt: 'x,y,r',

          chbh: '20',

          chs: '400x200',

          cht: 'bvg',

          chco: '76A4FB',

          chd: 't:50,30,10,60,65,90',

          chdl: 'Legend%3F',

          chdlp: 'b',

          chg: '0,10',

          chma: '|15',

          chtt: 'Daily+Usage'

        };

So, what I really need is access to the API that will allow me to translate all of the above (sample chart) into Java calls via com.google.gwt.visualization.client... calls.

I appreciate the help.
