• Z - z-coordinates: vector or matrix.
• sz - Marker size: numeric scalar, vector, [] (default: 36)
• c - Marker color: short color name, color name, RGB triplet or vector of colormap indices
• ax - a scalar graphics object value: parent container, specified as a axes.
• propertyName - a scalar string or row vector character. see help of 'line' for property list.
• propertyValue - a value.

Output argument

• s - a graphics object: scatter type or array of scatter.

Description

scatter(x, y, z) generates a scatter plot by placing circular markers at the coordinates defined by the vectors x, y and z.

If you intend to display a single dataset, ensure that both x, y and z are vectors of the same length.

To visualize multiple datasets on a shared set of axes, you can achieve this by using a matrix for either x, y or z, while keeping the other as a vector.

This allows you to overlay or compare multiple datasets within the same plot.

Scatter Properties:

AlphaData: Marker face transparency, 1 (default) or array the same size as XData

BeingDeleted: Flag indicating that the object is being deleted.

BusyAction: Callback queuing specified as 'queue' (default) or 'cancel'. The property determines how Nelson handles the execution of interrupting callbacks.

CData Marker colors: [] (default), RGB triplet, matrix of RGB triplets or vector.

marker color to use for each data series:

'k', 'black': Color Black

'y', 'yellow': Color Yellow

'm', 'magenta': Color Magenta

'c', 'cyan': Color Cyan

'r', 'red': Color Red

'b', 'blue': Color Blue

'g', 'green': Color Green

CDataMode Selection mode for CData: 'manual', 'auto' (default).

Children: Children.

CreateFcn: Component creation function.

DeleteFcn: Component deletion function.

DisplayName Legend label: character vector or string scalar, '' (default).

Interruptible: Callback interruption 'on' (default).

LineWidth Line width: scalar positive value.

MarkerMarker symbol:

marker specifies the symbol to be drawn at each data point:

'o': Circle symbol

'x': Times symbol

'+': Plus symbol

'*': Asterisk symbol

'.': Dot symbol

's': Square symbol

'd': Diamond symbol

'v': Downward-pointing triangle symbol

'^': Upward-pointing triangle symbol

'>': Left-pointing triangle symbol

'<': Right-pointing triangle symbol

MarkerEdgeColor Marker outline color: RGB triplet.

MarkerEdgeAlpha Marker edge transparency: scalar in range [0,1], 'flat or 1 (default).

To assign distinct transparency values to the edges of each point in a plot, set the AlphaData property to a vector matching the size of the XData property and set the MarkerEdgeAlpha property to 'flat'.

MarkerFaceColor Marker fill color: RGB triplet.

MarkerFaceAlpha Marker face transparency: scalar in range [0,1], 'flat or 1 (default).

To assign distinct transparency values to the faces of each point in a plot, set the AlphaData property to a vector matching the size of the XData property and set the MarkerFaceAlpha property to 'flat'.

Parent Parent container: Figure graphics object.

SizeData: Marker sizes:[] (default), scalar or vector.

Tag Object identifier: character vector, string scalar or '' (default).

Type: Type of graphics object 'scatter'.

UserData User data: array or []

Visible State of visibility: 'on' (default) or 'off'.

XData: x values: vector or matrix or [] (default).

YData: y values: vector or matrix or [] (default).

ZData: z values: vector or matrix or [] (default).

XDataMode Selection mode for XData: 'manual' or 'auto'.

Example

f = figure();
n = 100;
x = randn(n,1);
y = randn(n,1);
z = randn(n,1);
c = z;
sz = 20 + 50 * sqrt(x.^2 + y.^2 + z.^2);
scatter3(x, y, z, sz, c, 'filled');
