Bar chart in Javascript: stacked bars + grouped bars -


i'm looking javascript solution mix grouped , stacked bars beautiful graph, such provided protovis.

for example if want compare downloads on apple (ipads+iphones) devices android devices, might have (excuse terrible ascii art)

  60k |             ^ 50k |    #    ^   ^ 40k |#   #    ^  #^ 30k |@   #^   ^  #^ 20k |@^  #^  #^  @^ 10k |@^  @^  @^  @^    =================     jan feb mar apr  legend #: ipad downloads @: iphone downloads ^: android downloads

checkout google chart tools , google visualization

for instance can specify following:

enter image description here

cht=bvs chco=4d89f9,c6d9fd chd=t:10,50,60,80,40|   50,60,100,40,20 chds=0,160

let's if change chd to

enter image description here

cht=bvs chs=250x150 chco=4d89f9,c6d9fd chd=t:0,50,0,80,0, 10, 50, 40       60,0,100,0,20, 50, 100, 60 chds=0,160

take @ chart above (as if group chart, stacked). can append data after create stacked 'looking' group graph intended.
