Builtin index · Plotting

colormap(name)

Input: name · Output: no output

What it is

Sets the current panel's categorical/sequential palette to name (string — see the Markers & Styling reference below for the full list). An unknown name silently resolves to "default" rather than erroring.

Overloads

One call shape — this function is not overloaded.

Examples

From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.

figure()
t = linspace(0, 1, 200)
plot(t, sin(2 * pi * 5 * t))
xticks([0, 0.5, 1])
xticklabels("start", "mid", "end")
yticks([-1, 0, 1])
yticklabels("low", "zero", "high")
fontfamily("sans")
fontsize(tick = 10, label = 12, title = 14)
figure_background("#f7f7f7")
colormap("viridis")
colorbar()
grid()
box()
subplot(1, 1, 1)
xscale("linear")
yscale("linear")
title("Styled panel")

· plot: figure 8 (200 points)

How it works

colormap("viridis") -- see plotting::PALETTES; an unknown name is accepted and quietly resolves to "default" rather than erroring a whole script over a typo'd palette name.

From the note above this builtin in the interpreter, where the reasoning was written down as it was built.
