Detailed Description

A translation between data values and graph coordinates

Member Function Documentation

convert()

std::vector< float > Axis::convert ( QList< double >  values ) const

virtual

Translate data space values into plot space values. Subclasses will overload this method to enable different scaling methods (e.g. log scaling).

Reimplemented in LogAxis.

direction()

Axis::Direction Axis::direction

(

)

const

The direction in which the axis is pointing.

Todo:

This needs to be a proper enum to handle three dimensions

maximum()

double Axis::maximum

(

)

const

Get the maximum edge of the axis

minimum()

double Axis::minimum

(

)

const

Get the minimum edge of the axis

nudge

void Axis::nudge ( double  delta )

virtualslot

Shift the axis bounds by a given distance

Reimplemented in LogAxis.

setMaximum()

void Axis::setMaximum

(

const double

value

)

Set the maximum edge of the axis

setMinimum()

void Axis::setMinimum

(

const double

value

)

Set the minimum edge of the axis

tick()

double Axis::tick

(

int

index

)

const

Access the value of an individual tick label by index

tickCoord()

double Axis::tickCoord ( int  index ) const

virtual

Access the position of an individual tick label by index

Reimplemented in LogAxis.

tickCount()

int Axis::tickCount

(

)

const

The number of tick labels on the axis

tickLabels()

AxisTickLabels * Axis::tickLabels

(

)

The tick label model for this axis

Member Data Documentation

tics_

std::vector<double> Axis::tics_

protected

The tick labels values
