◆ KPlotAxis()
KPlotAxis::KPlotAxis |
( |
const QString & |
label = QString() | ) |
|
|
explicit |
Constructor, constructs an axis with the label label
.
◆ ~KPlotAxis()
KPlotAxis::~KPlotAxis |
( |
| ) |
|
◆ areTickLabelsShown()
bool KPlotAxis::areTickLabelsShown |
( |
| ) |
const |
- Returns
- whether tick labels will be drawn for this axis
◆ isVisible()
bool KPlotAxis::isVisible |
( |
| ) |
const |
- Returns
- whether the axis is visible or not
◆ label()
QString KPlotAxis::label |
( |
| ) |
const |
- Returns
- the label string for this axis
◆ majorTickMarks()
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()
◆ minorTickMarks()
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()
◆ setLabel()
void KPlotAxis::setLabel |
( |
const QString & |
label | ) |
|
Sets the axis label.
Set the label to an empty string to omit the axis label.
- Parameters
-
label | a string describing the data plotted on the axis. |
◆ setTickLabelFormat()
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
-
format | the format specification character |
fieldWidth | the 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. |
precision | the number of characters following the decimal point. |
◆ setTickLabelsShown()
void KPlotAxis::setTickLabelsShown |
( |
bool |
b | ) |
|
Determine whether tick labels will be drawn for this axis.
- Parameters
-
b | if true, tick labels will be drawn. |
◆ setTickMarks()
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
-
x0 | the minimum data coordinate of the axis. |
length | the range covered by the axis, in data units. |
- See also
- majorTickMarks()
-
minorTickMarks()
◆ setVisible()
void KPlotAxis::setVisible |
( |
bool |
visible | ) |
|
Sets the "visible" property of the axis.
- Parameters
-
visible | if true, this axis will be drawn on the KPlotWidget |
◆ tickLabel()
QString KPlotAxis::tickLabel |
( |
double |
value | ) |
const |
- Returns
- the ticklabel string for the given value, rendered according to the current format specification.
- Parameters
-
the | value to be rendered as a tick label. |
- See also
- setTickLabelFormat()
◆ tickLabelFormat()
char KPlotAxis::tickLabelFormat |
( |
| ) |
const |
- Returns
- the number format of the tick labels
◆ tickLabelPrecision()
int KPlotAxis::tickLabelPrecision |
( |
| ) |
const |
- Returns
- the number precision of the tick labels
◆ tickLabelWidth()
int KPlotAxis::tickLabelWidth |
( |
| ) |
const |
- Returns
- the field width of the tick labels
