Detailed Description

The main class, and handler for all of the trajectory data.

The main purpose of this class is to hold the trajectory data. Contains functions to read in trajectory data and output images. After outlier detection is run this class also holds information on the outlying trajectories and outlying partitions.

Member Function Documentation

void TrajData::OutputTrajectoryPlot

(

string

filePath

)

Output an eps image of the trajectories and outliers.

Makes a plot of the trajectories with gnuplot and highlights outlying trajectories and partitions. Uses default coloring and line widths: outlier trajectories colored red, line widths 2, and outlier partitions in a line width of 6.

The output file is specified with filePath, which should be an .eps file.

Parameters

filePath

[in] The desired path and filename of the eps file to output

void TrajData::OutputTrajectoryPlot	(	string	filePath,
		string	termSettings,
		string	oTrajColor,
		int	oTrajWidth,
		string	oPartColor,
		int	oPartWidth
	)

Output an eps image of the trajectories and outliers.

Makes a plot of the trajectories with gnuplot and highlights outlying trajectories and partitions. The output file is specified with filePath, which should be an eps file.

Parameters

filePath	[in] The desired path and filename of the eps file to output
termSettings	[in] the terminal settings passed to gnuplot to specify the output type and style. For example, for eps files specify "post eps", for png output specify "pngcairo", etc. Options can be specified afterward, such as "post eps color".
oTrajColor	[in] The color for outlying trajectories
oTrajWidth	[in] The line width for outlying trajectories
oPartColor	[in] The color for outlying partitions
oPartWidth	[in] The line width for outlying partitions

void TrajData::OutputTrajectoryPlotPNG

(

string

filePath

)

Output a png image of the trajectories and outliers.

Makes a plot of the trajectories with gnuplot and highlights outlying trajectories and partitions. Uses default coloring and line widths: outlier trajectories colored red, line widths 2, and outlier partitions in a line width of 6.

The output file is specified with filePath, which should be an .png file.

Parameters

filePath

[in] The desired path and filename of the png file to output

bool TrajData::readFile

(

string

filePath

)

Read trajectories from an input .traj file.

Parameters

[in]

filePath

The path to the input .traj file

Returns

True if read is successful
