Consider a BarLegend
showing a smooth gradient, like this one:
SeedRandom[36] data = RandomReal[{-0.5, 1}, 10] BarLegend[{"SolarColors", MinMax[data]}]
I would like to have two extra tick marks showing the actual minimal and maximal values.
MinMax[data] (* {-0.289979, 0.789597} *)
Is there a simple way to do this using BarLegend
?
I guess I could just use a DensityPlot instead. Here’s an example, with the CustomTicks package. But this is a bit too complicated to write up when one is in a hurry and doesn’t have personal utility functions handy. Is there an easier way?
DensityPlot[y, {x, 0, 1}, {y, Min[data], Max[data]}, PlotRangePadding -> None, ColorFunction -> "SolarColors", AspectRatio -> 15, ImageSize -> {Automatic, 250}, FrameTicks -> {{None, Sort@Join[ LinTicks[Min[data], Max[data], TickDirection -> Out, MajorTickLength -> 0.2, MinorTickLength -> 0.1], ({#, NumberForm[#, 2], {0, 0.2}, {}} &) /@ MinMax[data]]}, {None, None}} ]
