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.

t = linspace(0, 1, 200)
y = sin(2 * pi * 5 * t)
plot(t, y)
xspan(0.2, 0.4, color = "orange")
yspan(-0.3, 0.3, color = "green")
arrow(0.6, 0, 0.8, 0.8)
arrowtext(0.85, -0.5, 0.95, 0.2, "peak")
figure()
plot(t, t)
xbreak(0.3, 0.6)
