Lists, points & curve families

Try it step by step

1. Define a list with square brackets.
2. Use an index to retrieve an entry, or apply supported operations to the list.
3. Combine x and y lists to draw point pairs.
4. Use a short list of parameter values in an expression to draw a curve family.

Examples to try

Each card is one input. For definitions, enter the cards in order. Formula-only cards belong in the tool described above.

Options explained

List entries

Use explicit entries or supported ranges such as . List indexing starts at 1.

List calculations

Supported arithmetic and functions operate on list values. Matching shapes matter; incompatible lengths produce a diagnostic.

Nested lists

Lists may contain lists. A nested list is not automatically a matrix.

Point lists

Coordinate pairs and compatible coordinate lists can create multiple points.

Curve families

Several values can produce several curves from one expression. Up to 64 curves per expression and 256 per document are allowed.

Random, shuffle and repeat

Use these to create or reorganize samples; see Random samples for reproducibility.
