Hi Tom, I'm facing the same problem. Just to add up to description here, I figured out if I view my code in chart wizard or copy and paste the link created by chart wizard<http://chart.apis.google.com/chart?chxl=1:%7CScore%7C3:%7CAmount&chxp=1,100%7C3,100&chxr=0,-3.333,100%7C1,1.667,100%7C2,6.667,1500%7C3,6.667,100&chxs=1,676767,11.5,-1,l,676767%7C3,676767,11.5,1,l,676767&chxt=x,x,y,y&chs=300x230&cht=s&chco=008000&chds=0,100,10,100,-25,100&chd=t:25,12,40,30,80%7C36.739,54.342,90.194,67.44,71.32%7C54.231,47.7,79.848,66.135,68.304&chdl=Top10&chdlp=b&chg=20,20,10,4&chma=%7C5&chm=r,FF0000,0,0.2,0.21,-1%7CR,FF0000,0,0.3,0.31&chtt=ScoreCard>, the points are perfectly rendered, but if I copy and paste the same code (Click the Embed with Visualization API and copy/Paste the HTML) in the google code playground <http://code.google.com/apis/ajax/playground/> or my php file, then the points disappear from the chart. Also I get this at the end of the Chart "google.setOnLoadCallback(drawVisualization); " May anyone have already figured out why ?
