◆ setAutoAdjustHorizontalRangeToData()

void CartesianCoordinatePlane::setAutoAdjustHorizontalRangeToData ( unsigned int percentEmpty = 67 )

Automatically adjust horizontal range settings to the ranges covered by the model's values, when ever the data have changed, and then emit horizontalRangeAutomaticallyAdjusted.

By default the horizontal range is adjusted automatically, if more than 67 percent of the available horizontal space would be empty otherwise.

Range setting is adjusted if more than percentEmpty percent of the horizontal space covered by the coordinate plane would otherwise be empty. Automatic range adjusting can happen, when either all of the data are positive or all are negative.

Set percentEmpty to 100 to disable automatic range adjusting.

Parameters

percentEmpty The maximal percentage of horizontal space that may be empty.

◆ setFixedDataCoordinateSpaceRelation()

void CartesianCoordinatePlane::setFixedDataCoordinateSpaceRelation ( bool fixed )

Allows to specify a fixed data-space / coordinate-space relation. If set to true then fixed bar widths are used, so you see more bars as the window is made wider.

This allows to completely restrict the size of bars in a graph such that, upon resizing a window, the graphs coordinate plane will grow (add more ticks to x- and y-coordinates) rather than have the image grow.

◆ setGridAttributes()

void CartesianCoordinatePlane::setGridAttributes	(	Qt::Orientation	orientation,
		const GridAttributes &	a
	)

Set the attributes to be used for grid lines drawn in horizontal direction (or in vertical direction, resp.).

To disable horizontal grid painting, for example, your code should like this:

GridAttributes ga = plane->gridAttributes( Qt::Horizontal );
ga.setGridVisible( false );
plane-setGridAttributes( Qt::Horizontal, ga );

Note: setGridAttributes overwrites the global attributes that were set by AbstractCoordinatePlane::setGlobalGridAttributes. To re-activate these global attributes you can call resetGridAttributes.

◆ setHorizontalRange()

void CartesianCoordinatePlane::setHorizontalRange ( const QPair< qreal, qreal > & range )

Set the boundaries of the visible value space displayed in horizontal direction.

This is also known as the horizontal viewport.

By default the horizontal range is adjusted to the range covered by the model's data, see setAutoAdjustHorizontalRangeToData for details. Calling setHorizontalRange with a valid range disables this default automatic adjusting, while on the other hand automatic adjusting will set these ranges.

To disable use of this range you can either pass an empty pair by using the default constructor QPair() or you can set both values to the same which constitutes a null range.

Note: By default the visible data range often is larger than the range calculated from the data model (or set by setHoriz.|Vert.Range(), resp.). This is due to the built-in grid calculation feature: The visible start/end values get adjusted so that they match a main-grid line. You can turn this feature off for any of the four bounds by calling GridAttributes::setAdjustBoundsToGrid() for either the global grid-attributes or for the horizontal/vertical attrs separately.; To set only one of the ends of the range to a fixed value while keeping the other dynamically adjusted, use std::numeric_limits< qreal >::quiet_NaN() for the dynamic value.; If you use user defined vertical ranges together with logarithmic scale, only positive values are supported. If you set it to negative values, the result is undefined.

Parameters

range a pair of values representing the smallest and the largest horizontal value space coordinate displayed.

◆ setHorizontalRangeReversed()

void CartesianCoordinatePlane::setHorizontalRangeReversed ( bool reverse )

Sets whether the horizontal range should be reversed or not, i.e. small values to the left and large values to the right (the default) or vice versa.

Parameters

reverse Whether the horizontal range should be reversed or not

◆ setIsometricScaling()

void CartesianCoordinatePlane::setIsometricScaling ( bool onOff )

If onOff is true, enforce that X and Y distances are scaled by the same factor. This makes the plane's height a function of its width, and hasHeightForWidth() will return true.

◆ setVerticalRange()

void CartesianCoordinatePlane::setVerticalRange ( const QPair< qreal, qreal > & range )

Set the boundaries of the visible value space displayed in vertical direction.

This is also known as the vertical viewport.

By default the vertical range is adjusted to the range covered by the model's data, see setAutoAdjustVerticalRangeToData for details. Calling setVerticalRange with a valid range disables this default automatic adjusting, while on the other hand automatic adjusting will set these ranges.

To disable use of this range you can either pass an empty pair by using the default constructor QPair() or you can set setting both values to the same which constitutes a null range.

Note: By default the visible data range often is larger than the range calculated from the data model (or set by setHoriz.|Vert.Range(), resp.). This is due to the built-in grid calculation feature: The visible start/end values get adjusted so that they match a main-grid line.

If you set it to negative values, the result is undefined.

Parameters

range a pair of values representing the smallest and the largest vertical value space coordinate displayed.

◆ setVerticalRangeReversed()

void CartesianCoordinatePlane::setVerticalRangeReversed ( bool reverse )

Sets whether the vertical range should be reversed or not, i.e. small values at the bottom and large values at the top (the default) or vice versa.

Parameters

reverse Whether the vertical range should be reversed or not

◆ setXAxisStartAtZero()

void CartesianCoordinatePlane::setXAxisStartAtZero ( bool fixedStart )

Allows to fix the lower bound of X axis to zero when diagram is in first quadrant.

The default behavior is to lower x or y bound to be 0. If this behaviour is not wanted, either CartesianCoordinatePlane::setHorizontalRange could be used instead of letting KDChart auto-adjust the ranges, or this method can be used to disable this behavior.
