Color Trajectory Plot

A multi-color line based on a 2D trajectory with corresponding color data.

Colored Trajectory Plot

Version: 1.0

This chart creates a multi-color line based on a 2D trajectory with corresponding color data.

Syntax

• colorTrajectoryPlot(x,y) create a multi-color line plot following the 2D path specified by the coordinates x and y using the index of each coordinate to determine the color of the line. x and y must be numeric vectors of equal length.
• colorTrajectoryPlot(x,y,c) create a multi-color line plot following the 2D path specified by the coordinates x and y using values from c to determine the color of the line at each coordinate. x, y, and c must be numeric vectors of equal length.
• colorTrajectoryPlot() create a multi-color line plot using only name-value pairs.
• colorTrajectoryPlot(___,Name,Value) specifies additional options for the multi-color line plot using one or more name-value pair arguments. Specify the options after all other input arguments.
• colorTrajectoryPlot(parent,___) creates the multi-color line plot in the specified parent.
• h = colorTrajectoryPlot(___) returns the colorTrajectoryPlot object. Use h to modify properties of the plot after creating it.

Name-Value Pair Arguments/Properties

• XData (n x 1 numeric vector) x-coordinates of the trajectory.
• YData (n x 1 numeric vector) y-coordintaes of the trajectory.
• ColorData (n x 1 numeric vector) data used to determine the color of the line.
• Colormap (m x 3 matrix of RGB triplets) colormap used to convert ColorData into colors.
• ColorLimits (1 x 2 numeric vector) limits used to convert ColorData into colors.
• ColorLimitsMode ('auto' or 'manual') mode for the color limits.
• ColorbarVisible (scalar matlab.lang.OnOffSwitchState) display the colorbar or not.
• LineWidth (scalar positive double) line width of the trajectory.
• TitleText (n x 1 string vector) title of the plot.
• SubtitleText (n x 1 string vector) subtitle of the plot.
• ColorbarLabel (n x 1 string vector) label on the colorbar.

Example

Create a multi-color trajectory plot using x, y, and color data generated by the helper script randomWalk.

[x,y,c] = randomWalk;
c = colorTrajectoryPlot(x,y,c);
c.ColorbarLabel = "Firing Rate (Hz)";
colormap(hot(256))
