Line Interpolation / Smoothing :

By default Chartist uses a cardinal spline algorithm to smooth the lines. However, like all other things in Chartist, this can be customized easily! Check out the API Documentation for more smoothing options.

Series Overrides :
By naming your series using the series object notation with a name property, you can enable the individual configuration of series specific settings.
showLine, showPoint, 
showArea and even the smoothing function can be overriden per series! And guess what? You can even override those series settings in the responsive configuration! Check the example code for more details.
