Note: Many of the histogram references need work.

CSI - timing was goofy in reference (or made with some strange trigger
set?). RC histogram somehow ended up in the main page of CsI plots.

DC - some plots in reference have frowny faces.

SCIA - hitmap looks very sparse in reference.

Please take a look at your favorite reference section.
