[Seaside] SeaChart - current version?

[Markus Fritsche]

Hello,

I loaded PlotKit-0.9.1 from squeaksource, but it doesn't seem to work
with the Seaside Image downloaded from seaside.st (the 'Oneclick'
Image). I get a walkback:

MessageNotUnderstood: WARenderCanvas>>canvas

Which version (if any) should work with Seaside-2.8?
