What steps will reproduce the problem? Please provide a link to a
demonstration page if at all possible, or attach code.

When this code is executed, "Large" gets dropped and "Small" only is
displayed in the chart (column Z):

function drawVisualization(){
var data = new google.visualization.DataTable();
data.addColumn('string', 'State');
data.addColumn('date', 'Date');
data.addColumn('string', 'Size');
data.addColumn('number', 'X');
data.addColumn('number', 'Y');
data.addColumn('number', 'Z');
var s = new Array();
s.push(['CA',new  Date ('05/01/2010'),'Small',8.7,0.3,9694]);
s.push(['NY',new  Date ('05/01/2010'),'Small',7.9,0.3,4266]);
s.push(['TX',new  Date ('05/01/2010'),'Small',9.5,0.3,2581]);
s.push(['CA',new  Date ('05/01/2010'),'Large',10.9,0.3,3252]); 
s.push(['NY',new  Date ('05/01/2010'),'Large',6.5,0.2,988]); 
s.push(['TX',new  Date ('05/01/2010'),'Large',12.3,0.3,776]); 
s.push(['CA',new  Date ('05/02/2010'),'Small',8.6,0.4,9697]); 
s.push(['NY',new  Date ('05/02/2010'),'Small',8.9,0.5,4271]);
s.push(['TX',new  Date ('05/02/2010'),'Small',9.2,0.4,2588]);
s.push(['CA',new  Date ('05/02/2010'),'Large',11.7,0.4,3225]);
s.push(['NY',new  Date ('05/02/2010'),'Large',7.7,0.3,998]);
s.push(['TX',new  Date ('05/02/2010'),'Large',13.5,0.5,734]);   
s.push(['CA',new  Date ('05/03/2010'),'Small',14.4,1.2,10237]); 
s.push(['NY',new  Date ('05/03/2010'),'Small',15.2,1.5,4476]);
s.push(['TX',new  Date ('05/03/2010'),'Small',18.0,1.5,2805]); 
s.push(['CA',new  Date ('05/03/2010'),'Large',14.4,0.9,3109]);
s.push(['NY',new  Date ('05/03/2010'),'Large',8.5,0.7,994]);
s.push(['TX',new  Date ('05/03/2010'),'Large',18.5,1.2,804]);

data.addRows(s);

 var chart = new 
google.visualization.MotionChart(document.getElementById('visualization'));
 chart.draw(data, {width: 600, height:300}); 
}

Correction: "Small" gets dropped and "Large" only is displayed.

And it's actually column Size in the code. Sorry for the typos. Still the the core of
the issue is the same - values get dropped.
