Detailed Description

An axis for displaying and scaling numerical data.

Member Function Documentation

bool NumberAxis::AcceptDataset ( Dataset *  dataset )

protectedvirtual

Checks whether dataset can be accepted by this axis. Must be implemented by derivative classes. XXX: maybe remove this method later.

Parameters

dataset

dataset to be checked

Returns

true - if dataset can be accepted, false overwise

Implements Axis.

void NumberAxis::GetDataBounds ( double &  minValue, double &  maxValue  ) const

virtual

Returns bounds, taken from data, eg. real min-max value.

Parameters

minValue	output minimal data value
maxValue	output maximal data value

Implements Axis.

Here is the caller graph for this function:

void NumberAxis::GetLabel ( size_t  step, wxString &  label  )

protectedvirtual

Returns label on step.

Parameters

step	step index
label	output label

Implements LabelAxis.

Reimplemented in LogarithmicNumberAxis, and JulianDateAxis.

Here is the call graph for this function:

Here is the caller graph for this function:

size_t NumberAxis::GetLabelCount

(

)

const

Returns label count, to be draw on axis.

Returns

label count, to be draw on axis

Here is the caller graph for this function:

double NumberAxis::GetMultiplier

(

)

const

Returns multiplier for values.

Returns

multiplier

double NumberAxis::GetValue ( size_t  step )

protectedvirtual

Returns value on step.

Parameters

step	step index

Returns

value on step

Implements LabelAxis.

Reimplemented in LogarithmicNumberAxis.

Here is the caller graph for this function:

void NumberAxis::IntegerValues ( bool  intValues = true )

inline

Set whether to use integer values instead of doubles.

Parameters

intValues

if true than use integer values, false - double values

bool NumberAxis::IsEnd ( size_t  step )

protectedvirtual

Check whether step is last.

Parameters

step

step

Returns

true if step is last

Implements LabelAxis.

void NumberAxis::SetFixedBounds	(	double	minValue,
		double	maxValue
	)

Make data bounds fixed.

Parameters

minValue	minimal data value
maxValue	maximal data value

void NumberAxis::SetLabelCount ( size_t  labelCount )

inline

Sets count of labels.

Parameters

labelCount

count of labels

void NumberAxis::SetMultiplier

(

double

multiplier

)

Sets multiplier for values.

Parameters

multiplier

multiplier

void NumberAxis::SetTickFormat ( const wxString &  tickFormat )

inline

Sets format for tick marks.

Parameters

tickFormat

tick format

Here is the caller graph for this function:

void NumberAxis::UpdateBounds ( )

virtual

Performs axis bounds update after dataset/s change.

Implements Axis.

Reimplemented in LogarithmicNumberAxis.
