You could try to use a python code block to generate the array string
(you could even generate it on the controller), perhaps something like
this:
<?python
datasetString = reduce(lambda x,y: str(x) + "," + str(y), bars)
?>
var dataset = [${datasetString}];
The python code (by using the reduce function), will concatenate the
floats inside bars and generate a string like this: "1,2,3,4", then
you just print (output) that string in your javascript code.
You could use standard loop tools in Kid, but quite frankly I don't
see a straight forward way of knowing when you reached the last
element of the list in a loop, perhaps someone more versed in
Kid/Genshi templates could provide some enlightenment here.
Finally there is the way Mengu suggested which could be done with
build-in looping tools, but again I'm not a Genshi/Kid guru and
haven't used it in some time, testing is needed but you get the idea:
var dataset = [];
<py:for="item in bars">
dataset.push(${item});
</py:for>
