Opis szczegółowy

This QCPAxisTicker subclass generates ticks that are expressed with respect to a given symbolic constant with a numerical value specified with setPiValue and an appearance in the tick labels specified with setPiSymbol.

Ticks may be generated at fractions of the symbolic constant. How these fractions appear in the tick label can be configured with setFractionStyle.

The ticker can be created and assigned to an axis like this:

Dokumentacja składowych wyliczanych

enum QCPAxisTickerPi::FractionStyle

Defines how fractions should be displayed in tick labels.

Wartości wyliczeń
fsFloatingPoint	Fractions are displayed as regular decimal floating point numbers, e.g. "0.25" or "0.125".
fsAsciiFractions	Fractions are written as rationals using ASCII characters only, e.g. "1/4" or "1/8".
fsUnicodeFractions	Fractions are written using sub- and superscript UTF-8 digits and the fraction symbol.

Dokumentacja konstruktora i destruktora

QCPAxisTickerPi::QCPAxisTickerPi ( )

Constructs the ticker and sets reasonable default values. Axis tickers are commonly created managed by a QSharedPointer, which then can be passed to QCPAxis::setTicker.

void QCPAxisTickerPi::setFractionStyle ( QCPAxisTickerPi::FractionStyle style )

Sets how the numerical/fractional part preceding the symbolic constant is displayed in tick labels. See FractionStyle for the various options.

void QCPAxisTickerPi::setPeriodicity ( int multiplesOfPi )

Sets whether the axis labels shall appear periodicly and if so, at which multiplicity of the symbolic constant.

To disable periodicity, set multiplesOfPi to zero.

For example, an axis that identifies 0 with 2pi would set multiplesOfPi to two.

void QCPAxisTickerPi::setPiSymbol ( QString symbol )

Sets how the symbol part (which is always a suffix to the number) shall appear in the axis tick label.

If a space shall appear between the number and the symbol, make sure the space is contained in symbol.

void QCPAxisTickerPi::setPiValue ( double pi )

Sets the numerical value that the symbolic constant has.

This will be used to place the appropriate fractions of the symbol at the respective axis coordinates.
