Define tmpl, so creating a Line chart doesn't fail

[aliou]

Right now, using the scaleOverride and the scaleSteps options produces the following error:

ReferenceError: tmpl is not defined

This pull defines tmpl and fixes the issue.

Actually never mind, this seems to not show the right scale values... (this should be from one to five)

[aliou]

For some reason, these lines always returns the scaleStepWidth. Any idea?

Thanks. Good catch!

// Is `i`, not `1`.
value: (cfg.scaleStartValue + cfg.scaleStepWidth * 1).toFixed(getDecimalPlaces(cfg.scaleStepWidth))

If using the scaleOverride, scaleSteps scaleStepWidth and scaleStartValue must be required. See http://www.chartjs.org/docs/#lineChart-chartOptions.

Cool, thanks ! :+1:

I will add some test cases.
