- just a heads-up that color bars have been completely revamped in master. See the matrix visualization examples in http://toyplot.readthedocs.org/en/latest/matrix-visualization.html
, plus options for adding color scales to axes and the canvas in http://toyplot.readthedocs.org/en/latest/labels-and-legends.html
. For those interested in looking under the hood, the revised color scales are actually just the first application of the new NumberLine axes, so there will be interesting new ways to combine them with other marks to come!
