Create track plotter

Syntax

tPlotter = trackPlotter(tp)

tPlotter = trackPlotter(tp,Name,Value)

Description

tPlotter = trackPlotter(tp) creates a track plotter for use with the theater plot tp.

tPlotter = trackPlotter(tp,Name,Value) creates a track plotter with additional options specified by one or more Name,Value pair arguments.

Plot Tracks in Theater Plot

Open Script

Create a theater plot. Create a track plotter with DisplayName set to 'Tracks' and with HistoryDepth set to 5.

tp = theaterPlot('XLim',[0,90],'YLim',[-35,35]);
tPlotter = trackPlotter(tp,'DisplayName','Tracks','HistoryDepth',5);

Update the track plotter with three tracks labeled 'T1', 'T2', and 'T3' with start positions in units of meters all starting at (30, 5, 1) with corresponding velocities (in m/s) of (3, 0, 1), (3, 2, 2) and (3, -3, 5), respectively. Update the tracks with the velocities for ten iterations.

positions = [30, 5, 1; 30, 5, 1; 30, 5, 1];
velocities = [3, 0, 1; 3, 2, 2; 3, -3, 5];
labels = {'T1','T2','T3'};
for i=1:10
    plotTrack(tPlotter, positions, velocities, labels)
    positions = positions + velocities;
end

This animation loops through all the generated plots.

Input Arguments

`tp` — Theater plot
`theaterPlot` object

Theater plot, specified as a theaterPlot object.

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: 'MarkerSize',10

`'DisplayName'` — Plot name to display in legend
character vector | string scalar

Plot name to display in legend, specified as the comma-separated pair consisting of 'DisplayName' and a character vector or string scalar. If no name is specified, no entry is shown.

Example: 'DisplayName','Radar Detections'

`'HistoryDepth'` — Number of previous track updates to display
`0` (default) | nonnegative integer less than or equal to 10,000

Number of previous track updates to display, specified as the comma-separated pair consisting of 'HistoryDepth' and a nonnegative integer less than or equal to 10,000. If set to 0, then no previous updates are rendered.

`'ConnectHistory'` — Connect tracks flag
`'off'` (default) | `'on'`

Connect tracks flag, specified as either 'on' or 'off'. When set to 'on', tracks with the same label or track identifier between consecutive updates are connected with a line. This property can only be specified when creating the trackPlotter. The default is 'off'.

To use the trackIDs input argument of plotTrack, 'ConnectHistory' must be 'on'. If trackIDs is omitted when 'ConnectHistory' is 'on', then the track identifiers are derived from the labels input instead.

`'ColorizeHistory'` — Colorize track history
`'off'` (default) | `'on'`

Colorize track history, specified as either 'on' or 'off'. When set to 'on', tracks with the same label or track identifier between consecutive updates are connected with a line of a different color. This property can only be specified when creating the trackPlotter.The default is 'off'.

ColorizedHistory is applicable only when ConnectHistory is 'on'.

`'Marker'` — Marker symbol
`'s'` (default) | character vector | string scalar

Marker symbol, specified as the comma-separated pair consisting of 'Marker' and one of these symbols.

Value	Description
`'o'`	Circle
`'+'`	Plus sign
`'*'`	Asterisk
`'.'`	Point
`'x'`	Cross
`'_'`	Horizontal line
`'\|'`	Vertical line
`'square'` or `'s'`	Square
`'diamond'` or `'d'`	Diamond
`'^'`	Upward-pointing triangle
`'v'`	Downward-pointing triangle
`'>'`	Right-pointing triangle
`'<'`	Left-pointing triangle
`'pentagram'` or `'p'`	Five-pointed star (pentagram)
`'hexagram'` or `'h'`	Six-pointed star (hexagram)
`'none'`	No markers

`'MarkerSize'` — Size of marker
`10` (default) | positive integer

Size of marker, specified as the comma-separated pair consisting of 'MarkerSize' and a positive integer in points.

`'MarkerEdgeColor'` — Marker outline color
`'black'` (default) | character vector | string scalar | RGB triplet | hexadecimal color code

Marker outline color, specified as the comma-separated pair consisting of 'MarkerEdgeColor' and a character vector, a string scalar, an RGB triplet, or a hexadecimal color code.

`'MarkerFaceColor'` — Marker fill color
`'none'` (default) | character vector | string scalar | RGB triplet | hexadecimal color code

Marker outline color, specified as the comma-separated pair consisting of 'MarkerFaceColor' and a character vector, a string scalar, an RGB triplet, a hexadecimal color code, or 'none'. The default is 'none'.

`'FontSize'` — Font size for labeling tracks
`10` (default) | positive integer

Font size for labeling tracks, specified as the comma-separated pair consisting of 'FontSize' and a positive integer that represents font point size.

`'LabelOffset'` — Gap between label and positional point
`[0 0 0]` (default) | three-element row vector

Gap between label and positional point it annotates, specified as the comma-separated pair consisting of 'LabelOffset' and a three-element row vector. Specify the [x y z] offset in meters.

`'VelocityScaling'` — Scale factor for magnitude length of velocity vectors
`1` (default) | positive scalar

Scale factor for magnitude length of velocity vectors, specified as the comma-separated pair consisting of 'VelocityScaling' and a positive scalar. The plot renders the magnitude vector value as VK, where V is the magnitude of the velocity in meters per second, and K is the value of VelocityScaling.

`'Tag'` — Tag to associate with the plotter
`'PlotterN'` (default) | character vector | string scalar

Tag to associate with the plotter, specified as the comma-separated pair consisting of 'Tag' and a character vector or string scalar. The default value is 'PlotterN', where N is an integer that corresponds to the Nth plotter associated with the theaterPlot.

Tags provide a way to identify plotter objects, for example when searching using findPlotter.
