Hello, I think this is a bug in Google Charts:
I use 3 underscores to omit values, but they are still displayed as -1 here: http://chart.apis.google.com/chart?chs=700x280&cht=bvo&chco=3399FF,CCCCFF&chd=t%3a_,_,_,-2064|3927,6133,8053,2802&chxl=0%3a|2010-44|2010-45|2010-46|2010-47&chxt=x,y&chxs=0,006633,12,0,_,000000&chxr=1,-2064,8053&chds=-2064,8053&chbh=140,10,0&chm=N,,0,,12|N,,1,,12 Probably -1 is used internally to indicate NULL values, but this fails here because the chds range starts at a lower negative value. The workaround would be to use a (MIN-1) value or maybe something else...
