Feature request: option to pre-process the data

[sahuguet]

Hi,

big fan of the framework.

There are two things I would like to do with the data before rendering it:

• reverse the order of the data e.g. [1,2,3] becomes [3,2,1]
• accumulate values e.g. [1,1,3,4] becomes [1,2,5,9]

Having a callback function to preprocess the value array before it is rendered should do the trick.

regards,

Arnaud

Why do you need the plugin to do this, rather than just handling it from your own code before the sparkline() function is called?
