Hi,

If I have 2 data points e.g. chd=t:92,64 then a line displays fine,

http://chart.apis.google.com/chart?cht=lc&chd=t:92,64&chs=400x200&chg=100.00,100.00&chm=c,FF0000,0,1,20.0&chxt=x,y&chxl=0:|Mar|1:|300|400|500|600|700|800|900

however how can I just display a marker for a single data point e.g.
chd=t:92?

Doing this doesn't display anything:

 
http://chart.apis.google.com/chart?cht=lc&chd=t:92&chs=400x200&chg=100.00,100.00&chm=c,FF0000,0,1,20.0&chxt=x,y&chxl=0:|Mar|1:|300|400|500|600|700|800|900

Thanks, Jason
