pathPlotter
Path plotter for bird's-eye plot
Description
creates a pPlotter
= pathPlotter(bep
)PathPlotter
object that configures the display of actor paths
on a bird's-eye plot. The PathPlotter
object is stored in the
Plotters
property of the input birdsEyePlot
object, bep
. To display the paths, use the
plotPath
function.
sets properties using one or more pPlotter
= pathPlotter(bep
,Name,Value
)Name,Value
pair arguments. For
example, pathPlotter(bep,'DisplayName','Actor paths')
sets the display
name that appears in the bird's-eye-plot legend.
Examples
Plot Path of Ego Vehicle
Create a 3-meter-wide lane.
lb = parabolicLaneBoundary([-0.001,0.01,1.5]); rb = parabolicLaneBoundary([-0.001,0.01,-1.5]);
Compute the lane boundary model manually from 0 to 30 meters along the x-axis.
xWorld = (0:30)'; yLeft = computeBoundaryModel(lb,xWorld); yRight = computeBoundaryModel(rb,xWorld);
Create a bird's-eye plot and lane boundary plotter. Display the lane information on the bird's-eye plot.
bep = birdsEyePlot('XLimits',[0 30],'YLimits',[-5 5]); lanePlotter = laneBoundaryPlotter(bep,'DisplayName','Lane boundaries'); plotLaneBoundary(lanePlotter,{[xWorld,yLeft],[xWorld,yRight]});
Create a path plotter. Create and display the path of an ego vehicle that travels through the center of the lane.
yCenter = (yLeft + yRight)/2; egoPathPlotter = pathPlotter(bep,'DisplayName','Ego vehicle path'); plotPath(egoPathPlotter,{[xWorld,yCenter]});
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: pathPlotter('Color','red')
sets the color of the path to
red.
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.
Color
— Path color
[0 0 0]
(black) (default) | RGB triplet | hexadecimal color code | color name | short color name
Path color, specified as the comma-separated pair consisting of
'Color'
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" | |
"green" | "g" | [0 1 0] | "#00FF00" | |
"blue" | "b" | [0 0 1] | "#0000FF" | |
"cyan"
| "c" | [0 1 1] | "#00FFFF" | |
"magenta" | "m" | [1 0 1] | "#FF00FF" | |
"yellow" | "y" | [1 1 0] | "#FFFF00" | |
"black" | "k" | [0 0 0] | "#000000" | |
"white" | "w" | [1 1 1] | "#FFFFFF" | |
"none" | Not applicable | Not applicable | Not applicable | No color |
Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB® uses in many types of plots.
RGB Triplet | Hexadecimal Color Code | Appearance |
---|---|---|
[0 0.4470 0.7410] | "#0072BD" | |
[0.8500 0.3250 0.0980] | "#D95319" | |
[0.9290 0.6940 0.1250] | "#EDB120" | |
[0.4940 0.1840 0.5560] | "#7E2F8E" | |
[0.4660 0.6740 0.1880] | "#77AC30" | |
[0.3010 0.7450 0.9330] | "#4DBEEE" | |
[0.6350 0.0780 0.1840] | "#A2142F" |
LineStyle
— Path line style
':'
(default) | '-'
| '--'
| '-.'
| 'none'
Path line style, specified as the comma-separated pair consisting of
'LineStyle'
and one of the options listed in this table.
Line Style | Description | Resulting Line |
---|---|---|
"-" | Solid line |
|
"--" | Dashed line |
|
":" | Dotted line |
|
"-." | Dash-dotted line |
|
"none" | No line | No line |
Tag
— Tag associated with plotter object
'PlotterN
'
(default) | character vector | string scalar
N
'Tag associated with the plotter object, specified as the comma-separated pair
consisting of 'Tag'
and a character vector or string scalar. The
default value is 'Plotter
, where
N
'N
is an integer that corresponds to the
N
th plotter associated with the input birdsEyePlot
object.
Output Arguments
pPlotter
— Path plotter
PathPlotter
object
Path plotter, returned as a PathPlotter
object. You can modify this
object by changing its property values. The property names correspond to the name-value
pair arguments of the pathPlotter
function.
pPlotter
is stored in the Plotters
property of the input birdsEyePlot
object,
bep
. To plot the paths, use the plotPath
function.
