Axis for KPlotWidget
Contains all data for drawing an axis including format specification axis labels. Author Andreas Nicolai Version: 1.0 |
|
Constructor, constructs an axis with the label label. |
|
|
|
Returns whether tick labels will be drawn for this axis |
|
Returns whether the axis is visible or not |
|
Returns the label string for this axis |
|
Returns the list of coordinates of the major tickmarks for this axis
the positions of tickmarks are automatically computed by setTickMarks().
See also setTickMarks() See also minorTickMarks() |
|
Returns the list with the minor tickmarks
the positions of tickmarks are automatically computed by setTickMarks().
See also setTickMarks() See also majorTickMarks() |
|
Sets the axis label.
Set the label to an empty string to omit the axis label.
label - a string describing the data plotted on the axis. |
|
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. 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. |
|
Determine whether tick labels will be drawn for this axis.
b - if true, tick labels will be drawn. |
|
Determine the positions of major and minor tickmarks for this axis.
this function is called by KPlotWidget whenever the plot's
limits are modified.
x0 - the minimum data coordinate of the axis. length - the range covered by the axis, in data units. See also majorTickMarks() See also minorTickMarks() |
|
Sets the "visible" property of the axis.
visible - if true, this axis will be drawn on the KPlotWidget |
|
Returns the ticklabel string for the given value, rendered according
to the current format specification.
the - value to be rendered as a tick label. See also setTickLabelFormat() |
|
Returns the number format of the tick labels |
|
Returns the number precision of the tick labels |
|
Returns the field width of the tick labels |
