This work fine

Answer 1

Just wanted to provide an answer using Razor syntax:

We have a Dictionary that we are rendering for a jQuery Sparkline, in the form of "an array of arrays".

var usageData = [ @string.Join(",", Model.UsageData.Select(d => string.Format("[{0},{1}]", d.Key, d.Value)).ToArray()) ];

Which is used like so:

$('#sparkline').UsageSparkline(usageData, { tooltipFormatter: cachedTooltips });

This is what we get when viewing the source:

var usageData = [ [-13,0],[-12,1],[-11,0],[-10,0],[-9,1],[-8,1],[-7,0],[-6,2],[-5,2],[-4,0],[-3,0],[-2,9],[-1,3],[0,4] ];
$('#sparkline').UsageSparkline(usageData, { tooltipFormatter: cachedTooltips });
