Member Function Documentation

unsigned int AddPlot

(

)

Add a new plot to the canvas.

Returns

Unique id of the plot

unsigned int AddVariable	(	const std::string &	_variable,
		const unsigned int	_plotId = EmptyPlot
	)

Add a new variable to a plot.

Parameters

[in]	_variable	Name of the variable.
[in]	_plotId	Unique id of the plot to add the variable to.

Returns

Unique id of the variable

void CanvasDeleted ( )

signal

Qt signal to request self-deletion.

void Clear

(

)

Clear the canvas and remove all variables and plots.

virtual bool eventFilter ( QObject *  _o, QEvent *  _event  )

virtual

Used to filter scroll wheel events.

Parameters

[in]	_o	Object that receives the event.
[in]	_event	Pointer to the event.

Returns

True if event was handled.

void Export	(	const std::string &	_dirName,
		const FileType	_type
	)		const

Export to PDF files in the given directory.

Parameters

[in]	_dirName	Name of the directory to save the files into.
[in]	_type	File type, such as PDFFile or CSVFile.

unsigned int PlotByVariable

(

const unsigned int

_variableId

)

const

Get the plot id which the variable is plotted in.

Parameters

[in]

_id

Unique id of the variable

Returns

Unique id of the plot

unsigned int PlotCount

(

)

const

Get the number of plots in this canvas.

Returns

Number of plots

PlotCurveWeakPtr PlotCurve

(

const unsigned int

_variableId

)

Get the curve associated with the variable.

Parameters

[in]

_id

Unique id of the variable

Returns

A pointer to the PlotCurve object.

std::vector<IncrementalPlot *> Plots

(

)

const

Get all the plots in this canvas.

Returns

A list of plots in this canvas.

void RemovePlot

(

const unsigned int

_plotId

)

Remove a plot from the canvas.

Parameters

[in]

_id

Unique id of the plot

void RemoveVariable	(	const unsigned int	_id,
		const unsigned int	_plotId = EmptyPlot
	)

Remove a variable from a plot.

Parameters

[in]	_id	Unique id of the variable
[in]	_plotId	Unique id of plot to remove the variable from. If EmptyPlot is specified, the function will search through all plots for the variable and remove it from the plot if found.

void Restart
