`scatter`

Scatter plot: markers at given positions, with optional size and color for each point.

Syntax

scatter(x, y)

Draws a circle at each point (x(k), y(k)).

scatter(x, y, sz)

Sets the marker area; a vector gives each point its own size.

scatter(x, y, sz, c)

Sets the color: a color spec, an RGB triplet, or a vector mapped through the colormap.

scatter(___, 'filled')

Fills the markers.

scatter(___, mkr)

Chooses the marker shape, such as 's' or '^'.

s = scatter(___)

Also returns the Scatter object.

Description

scatter is for relationships between variables where each point stands alone, and it can encode two more variables through size and color. For a plain line through the points, plot is lighter and faster.

Input arguments

x, y: Vectors of the same length.
sz: Marker area in points squared; scalar or one per point. The default is 36.
c: Color data. A vector of values is mapped through the current colormap.

Output arguments

s: Scatter object; read or change SizeData, CData, MarkerFaceColor and more.

Example

Size and color per point

rng(1)
x = rand(1, 40);
y = x + 0.2*rand(1, 40);
scatter(x, y, 20 + 200*rand(1, 40), x, 'filled')

In the app, the figure is drawn below the code.
