Users can choose to highlight some series

[breznak]

A feedback from users, they want to be able to highlight some (a few) series while still visualizing all of them.

TODO:

• [ ] add a row with checkboxes 'Highlight'
• [ ] change options in graph to highlight the selected series

USECASE:

• on multi-series data
  • for example the OPF file
• you want to see/feel all of the variables
• but focus on one/few (anomalyScore, consumption)

the highlightSelectedSeries and strokeBorderWidth functionality seems to be causing unbearable slowdown in the graph rendering, we should investigate and report upstream. https://github.com/nupic-community/nupic.visualizations/blob/master/client/src/app/appCtrl.js#L542-L547

One way to do this without a performance hit would be to change the colors of the plot lines. We would need to write a little algorithm that can output a lightened version of a given color. The lightened colors would then fade into the background, giving the other plot lines prominence.

Yes, or maybe a default transparency ~80% and 100% for selected. In the "Profiling" issue we still need to asses what throttles the performance. And I wanted to double-check with you, the slow-down should not be caused by anything at our side, right? So we can raise an issue upstream..
