After a closer look at the ScatterChart Data_Format:
http://code.google.com/apis/visualization/documentation/gallery/scatterchart.html#Data_Format
It looks like the last two lines should be:
,{c:[{v:0},{v:'--'},null]} // blank left column
,{c:[{v:3},{v:'--'},null]} // blank right column
instead of:
,{c:[{v:0},{v:'--'},{v:0}]} // empty left Set -- with
point at [0,0]
,{c:[{v:3},{v:'--'},{v:0}]} // empty right Set
If you want to still have it start from 0 instead of the lowest value
in your set (~ 40),
then add:
,{c:[null,null,{v:0}]} // min y=0
as the last row. "null" means that the value is not displayed.
