trackPlotter
Track plotter for bird's-eye plot
Description
creates a tPlotter
= trackPlotter(bep
)TrackPlotter
object that configures the display of tracks on a
bird's-eye plot. The TrackPlotter
object is stored in the
Plotters
property of the input birdsEyePlot
object, bep

plotTrack
function.
sets properties using one or more tPlotter
= trackPlotter(bep
,Name,Value
)Name,Value
pair arguments. For
example, trackPlotter(bep,'DisplayName','Tracks')
sets the display name

Examples
Create and Display Labeled Tracks on Bird's-Eye Plot
Create a bird's-eye plot with an x-axis range from 0 to 90 meters and a y-axis range from –35 to 35 meters. Create a track plotter that displays up to seven history values for each track and offsets labels by 3 meters in front of the tracks.
bep = birdsEyePlot('XLim',[0 90],'YLim',[-35 35]); tPlotter = trackPlotter(bep,'DisplayName','Tracks','HistoryDepth',7,'LabelOffset',[3 0]);
Set the positions and velocities of three labeled tracks.
positions = [30, 5; 30, 5; 30, 5]; velocities = [3, 0; 3, 2; 3, -3]; labels = {'T1','T2','T3'};
Display the tracks for 10 trials. The bird's-eye plot shows the seven history values specified previously.
for i=1:10 plotTrack(tPlotter,positions,velocities,labels); positions = positions + velocities; end
Input Arguments
bep
— Bird’s-eye plot
birdsEyePlot
object
Bird’s-eye plot, specified as a birdsEyePlot
object.
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Before R2021a, use commas to separate each name and value, and enclose
Name
in quotes.
Example: trackPlotter('Marker','*')
sets the marker symbol for tracks
to an asterisk.
DisplayName
— Plotter name to display in legend
''
(default) | character vector | string scalar
Plotter name to display in legend, specified as the comma-separated pair consisting of
'DisplayName'
and character vector or string scalar. If you do
not specify a name, the bird's-eye plot does not display a legend entry for the
plotter.
HistoryDepth
— Number of previous track updates to display
0
(default) | integer in the range [0, 100]
Number of previous track updates to display, specified as the comma-separated pair
consisting of 'HistoryDepth'
and an integer in the range [0, 100].
When you set this value to 0
, the bird's-eye plot displays no
previous updates.
Marker
— Marker symbol for tracks
'square'
(default) | '+'
| '*'
| '.'
| 'x'
| ...
Marker symbol for tracks, specified as the comma-separated pair consisting of
'Marker'
and one of the markers in this table.
Marker | Description | Resulting Marker |
---|---|---|
"o" | Circle |
|
"+" | Plus sign |
|
"*" | Asterisk |
|
"." | Point |
|
"x" | Cross |
|
"_" | Horizontal line |
|

|
"v" | Downward-pointing triangle |
|
">" | Right-pointing triangle |
|
"<" | Left-pointing triangle |
|
"pentagram" | Pentagram |
|
"hexagram" | Hexagram |

"none" | No markers | Not applicable |
MarkerSize
— Size of marker for tracks
10
(default) | positive integer
Size of marker for tracks, specified as the comma-separated pair consisting of
'MarkerSize'
and a positive integer in points.
MarkerEdgeColor
— Marker outline color for tracks
[0 0 0]
(black) (default) | RGB triplet | hexadecimal color code | color name | short color name
Marker outline color for tracks, specified as the comma-separated pair consisting
of 'MarkerEdgeColor'
and an RGB triplet, a hexadecimal color code,
a color name, or a short color name.
For a custom color, specify an RGB triplet or a hexadecimal color code.
An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range
[0,1]
, for example,[0.4 0.6 0.7]
.A hexadecimal color code is a string scalar or character vector that starts with a hash symbol (
#
) followed by three or six hexadecimal digits, which can range from0
toF
. The values are not case sensitive. Therefore, the color codes"#FF8800"
,"#ff8800"
,"#F80"
, and"#f80"
are equivalent.
Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.
Color Name | Short Name | RGB Triplet | Hexadecimal Color Code | Appearance |
---|---|---|---|---|
"red" | "r" | [1 0 0] | "#FF0000" | |
