Sorry I wrote bad the link of the first chart. Here it goes OK:

Chart with min in -59 is displayed in wrong way
http://chart.apis.google.com/chart?cht=bvs&chs=250x250&chd=t:10,0|4.48,0|15,-58.42|0,4.73|0,73.44&chco=4D89D9,C6D9FD,FF0000,00FF00,0000FF&chds=-59,80&chf=bg,s,edf5ff|c,s,f6e426&chtt=my_title&chdl=A|B|C|D|E&chdlp=r&chxt=x,y&chxl=0:|Col_1|Col_2&chxr=1,-59,80&chbh=r,1,0&chg=0,12.5

Chart with min in -60 is displayed in correct way (changing only this)
http://chart.apis.google.com/chart?cht=bvs&chs=250x250&chd=t:10,0|4.48,0|15,-58.42|0,4.73|0,73.44&chco=4D89D9,C6D9FD,FF0000,00FF00,0000FF&chds=-60,80&chf=bg,s,edf5ff|c,s,f6e426&chtt=my_title&chdl=A|B|C|D|E&chdlp=r&chxt=x,y&chxl=0:|Col_1|Col_2&chxr=1,-60,80&chbh=r,1,0&chg=0,12.5

Is this a bug or I'm doing something wrong?

Thanks.
