groupbar(x, y)

Input: x, y · Output: no output

What it is

Grouped (side-by-side) bar chart: x (Vec, category positions) and y (Mat or list of Vecs, one series per group of bars).

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.

x = 0 to 9
y = sin(x / 2)
figure()
stem(x, y)
figure()
stair(x, y)
figure()
groupbar([1, 2, 3], [3, 5, 2])
figure()
stackbar([1, 2, 3], [3, 5, 2])
figure()
Z = [1, 2, 3, 4, 5; 2, 3, 4, 5, 6; 3, 4, 5, 6, 7]
waterfall(0 to 4, Z)

output

· stem: figure 14 (10 points)
· stair: figure 15 (10 points)
· groupbar: figure 16 (3 points)
· stackbar: figure 17 (3 points)

How it works

stair is the only callable spelling: step is already a reserved keyword (to ... step ... ranges), so step(...) can't be a function call — it lexes as a keyword, not an identifier. The rendered marker is internally still "step".

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