Member Function Documentation

bool KPlotAxis::areTickLabelsShown ( ) const
Returns
whether tick labels will be drawn for this axis

Definition at line 57 of file kplotaxis.cpp.

bool KPlotAxis::isVisible ( ) const
Returns
whether the axis is visible or not

Definition at line 47 of file kplotaxis.cpp.

QString KPlotAxis::label ( ) const
Returns
the label string for this axis

Definition at line 72 of file kplotaxis.cpp.

QList< double > KPlotAxis::majorTickMarks ( ) const
Returns
the list of coordinates of the major tickmarks for this axis
Note
the positions of tickmarks are automatically computed by setTickMarks().
See also
setTickMarks()
minorTickMarks()

Definition at line 184 of file kplotaxis.cpp.

QList< double > KPlotAxis::minorTickMarks ( ) const
Returns
the list with the minor tickmarks
Note
the positions of tickmarks are automatically computed by setTickMarks().
See also
setTickMarks()
majorTickMarks()

Definition at line 189 of file kplotaxis.cpp.

void KPlotAxis::setLabel ( const QString label)

Sets the axis label.

Set the label to an empty string to omit the axis label.

Parameters
labela string describing the data plotted on the axis.

Definition at line 67 of file kplotaxis.cpp.

void KPlotAxis::setTickLabelFormat ( char  format = 'g',
int  fieldWidth = 0,
int  precision = -1 
)

Set the display format for converting the double value of the tick's position to the QString for the tick label.

Normally, the format character is one of 'e', 'E', 'f', 'g', or 'G' (see the documentation for QString::arg(double) for details).

In addition, it is possible to set the format character to 't'; in this case the tickmark value is interpreted as a time in hours, and the ticklabel string will be in "hh:mm" clock format. Note that when the format character is 't', the fieldWidth and prec values are ignored.

Parameters
formatthe format specification character
fieldWidththe number of characters in the output string. If set to 0, the string will be as wide as it needs to be to fully render the value.
precisionthe number of characters following the decimal point.

Definition at line 77 of file kplotaxis.cpp.

void KPlotAxis::setTickLabelsShown ( bool  b)

Determine whether tick labels will be drawn for this axis.

Parameters
bif true, tick labels will be drawn.

Definition at line 62 of file kplotaxis.cpp.

void KPlotAxis::setTickMarks ( double  x0,
double  length 
)

Determine the positions of major and minor tickmarks for this axis.

Note
this function is called by KPlotWidget whenever the plot's limits are modified.
Parameters
x0the minimum data coordinate of the axis.
lengththe range covered by the axis, in data units.

minorTickMarks()

void KPlotAxis::setVisible ( bool  visible)

Sets the "visible" property of the axis.

Parameters
visibleif true, this axis will be drawn on the KPlotWidget

Definition at line 52 of file kplotaxis.cpp.

QString KPlotAxis::tickLabel ( double  value) const
Returns
the ticklabel string for the given value, rendered according to the current format specification.
Parameters
thevalue to be rendered as a tick label.

Returns
the number format of the tick labels

Definition at line 89 of file kplotaxis.cpp.

int KPlotAxis::tickLabelPrecision ( ) const
Returns
the number precision of the tick labels

Definition at line 94 of file kplotaxis.cpp.

int KPlotAxis::tickLabelWidth ( ) const
Returns
the field width of the tick labels
