Interactive surface 3D

Sampled mathematical surfaces for seeing peaks, valleys, and overall shape across two inputs.

Purpose: Explore a sampled surface over two inputs and one output.
Use when: Overall shape, peaks, and valleys matter more than a single exact sample.
Avoid when: Users need to compare individual values or cannot use a three-dimensional view.
Equivalent data: Formula, domains, sample count, and downloadable CSV expose the full dataset.

y = i / 60, x = j / 60, z = sin(x × π) × sin(y × π), with i and j from -60 through 59

Exact surface data

Formula: y = i / 60, x = j / 60, z = sin(x × π) × sin(y × π), with i and j from -60 through 59

14400 ordered points. X domain [-1, 0.9833333333333333]; Y domain [-1, 0.9833333333333333]; Z domain [-1, 1].

y = i / 10, x = j / 10, z = sin(x² + y²) × x / π, with i and j from -30 through 29

Compare the examples as distinct sampled surfaces. Their formulas and domains identify what changes.

Go API

v0.0.1

The examples above cover behavior and composition. pkg.go.dev is the canonical reference for exported types, functions, methods, and Go documentation.

Enabled, disabled, hidden, and omitted wrapper behavior, controls, export, and client transitions are shared by every chart. Review chart controls, then compare static/vector and interactive capabilities.
