Could you try again, please, because specifying colors via the CHCO
parameter works for me:
http://chart.apis.google.com/chart?cht=bvs;
chxt=y,x
chs=600x200
chd=t:0,1,2,3,4,4,3,2,1,0
chds=0,4,0,100
chxl=1:||first|second|third|fourth|fifth|sixth|seventh|eight||0:|0|1|2|
3|4
chbh=15,50
I think your spacing solution is probably best. Regarding individual
colors, try: chco=ff|ff|dd|bb|99|77|55|
33|11|ff and the documentation discusses how colors repeat
if you define too few.
Good luck,
K
Unfortunately, no, but you can specify text for two x-labels (see
http://code.google.com/apis/chart/labels.html#axis_labels):
chxt=x,y,x
chxl=0:|Fine lines and wrinkes|Skin is firmer|Skin appeared|Overall
skin|2:|were reduced||more youthful|has improved
Or move to a horizontal bar chart...
