~PlotCurve

(

)

Destructor.

Member Function Documentation

bool Active

(

)

const

Get whether the curve is active.

Returns

Active state of the plot curve

void AddPoint

(

const ignition::math::Vector2d &

_pt

)

Add a point to the curve.

Parameters

[in]

_pt

Point to add.

void AddPoints

(

const std::vector< ignition::math::Vector2d > &

_pt

)

Add points to the curve.

Parameters

[in]

unsigned int Age

(

)

const

Get the age of the curve.

Returns

Curve age

void Attach

(

IncrementalPlot *

_plot

)

Attach the curve to a plot.

Parameters

[in]

_plot

Plot to attach to.

void Clear

(

)

Clear all data from the curve.

QwtPlotCurve* Curve

(

)

void Detach

(

)

Detach the curve from the plot.

unsigned int Id

(

)

const

unsigned int Size

(

)

const

Get the number of data points in the curve.

Returns

Number of data points.
