ylabel

Builtin index · Plotting

ylabel(text, [align=])

Input: text, align · Output: no output

What it is

Labels the current panel's y-axis with text (string). align= (string, "left"/"center"/"right", plus "bottom"/"top" for the rotated text, default "center") sets alignment. While yyaxis right is active, labels the *right* axis instead of the left one.

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.

scatterfit(t, y, 2)   # degree-2 polynomial fit through the scatter

xlabel("x")
ylabel("y")

plot(t, noisy, color = "#b0b0b0")
