> Project: Mahout
> Issue Type: New Feature
> Components: visiualization
> Affects Versions: 0.12
> Reporter: Andrew Palumbo
> Assignee: Andrew Palumbo
> Fix For: 0.13

> Attachments: drmSamplePlot2d.png

>
> Add basic 2d and 3d plotting capabilities to Mahout using the Smile library:
> https://github.com/haifengl/smile
> I've prototyped an {{mplot2d}} class here to sample a certain percentage of a
> DRM's data using {{drmSampleKRows()}} and to create a 2d plot from the
> resulting x,y coordinate matrix, and tested from the spark-shell as a POC.
> Extending to 3d should be trivial:
> The Smile-Plot library has some very nice plotting features, all of which can
> easily integrated into mahout:
