Hi there,

I'm testing it right now and I've found that when you select the time field
for the charts, Flotr2 is not using the "time" format. I don't know if this
could be fixed easily, but it will be really awesome to have that feature.

Including the time format is as simple as this in any Flotr2 chart:

graph = drawGraph({                    xaxis: {
    mode: 'time',                            },

Thus, if you detect that a column is called "time", then, the chart
should use that "mode" for the chart :-)
