Detailed Description

The QCP Namespace contains general enums and QFlags used throughout the QCustomPlot library

Enumeration Type Documentation

enum QCP::MarginSide

Defines the sides of a rectangular entity to which margins can be applied.

See Also

QCPLayoutElement::setAutoMargins, QCPAxisRect::setAutoMargins

Enumerator
msLeft	0x01 left margin
msRight	0x02 right margin
msTop	0x04 top margin
msBottom	0x08 bottom margin
msAll	0xFF all margins
msNone	0x00 no margin

enum QCP::AntialiasedElement

Defines what objects of a plot can be forcibly drawn antialiased/not antialiased. If an object is neither forcibly drawn antialiased nor forcibly drawn not antialiased, it is up to the respective element how it is drawn. Typically it provides a setAntialiased function for this.

AntialiasedElements is a flag of or-combined elements of this enum type.

See Also

QCustomPlot::setAntialiasedElements, QCustomPlot::setNotAntialiasedElements

Enumerator
aeAxes	0x0001 Axis base line and tick marks
aeGrid	0x0002 Grid lines
aeSubGrid	0x0004 Sub grid lines
aeLegend	0x0008 Legend box
aeLegendItems	0x0010 Legend items
aePlottables	0x0020 Main lines of plottables (excluding error bars, see element aeErrorBars)
aeItems	0x0040 Main lines of items
aeScatters	0x0080 Scatter symbols of plottables (excluding scatter symbols of type ssPixmap)
aeErrorBars	0x0100 Error bars
aeFills	0x0200 Borders of fills (e.g. under or between graphs)
aeZeroLine	0x0400 Zero-lines, see QCPGrid::setZeroLinePen
aeAll	0xFFFF All elements
aeNone	0x0000 No elements

enum QCP::PlottingHint

Defines plotting hints that control various aspects of the quality and speed of plotting.

See Also

QCustomPlot::setPlottingHints

Enumerator
phNone	0x000 No hints are set
phFastPolylines	0x001 Graph/Curve lines are drawn with a faster method. This reduces the quality especially of the line segment joins. (Only relevant for solid line pens.)
phForceRepaint	0x002 causes an immediate repaint() instead of a soft update() when QCustomPlot::replot() is called with parameter QCustomPlot::rpHint. This is set by default to prevent the plot from freezing on fast consecutive replots (e.g. user drags ranges with mouse).
phCacheLabels	0x004 axis (tick) labels will be cached as pixmaps, increasing replot performance.

enum QCP::Interaction

Defines the mouse interactions possible with QCustomPlot.

Interactions is a flag of or-combined elements of this enum type.

See Also

QCustomPlot::setInteractions

Enumerator
iRangeDrag	0x001 Axis ranges are draggable (see QCPAxisRect::setRangeDrag, QCPAxisRect::setRangeDragAxes)
iRangeZoom	0x002 Axis ranges are zoomable with the mouse wheel (see QCPAxisRect::setRangeZoom, QCPAxisRect::setRangeZoomAxes)
iMultiSelect	0x004 The user can select multiple objects by holding the modifier set by QCustomPlot::setMultiSelectModifier while clicking
iSelectPlottables	0x008 Plottables are selectable (e.g. graphs, curves, bars,... see QCPAbstractPlottable)
iSelectAxes	0x010 Axes are selectable (or parts of them, see QCPAxis::setSelectableParts)
iSelectLegend	0x020 Legends are selectable (or their child items, see QCPLegend::setSelectableParts)
iSelectItems	0x040 Items are selectable (Rectangles, Arrows, Textitems, etc. see QCPAbstractItem)
iSelectOther	0x080 All other objects are selectable (e.g. your own derived layerables, the plot title,...)

Function Documentation

bool QCP::isInvalidData ( double  value )

inline

Returns whether the specified value is considered an invalid data value for plottables (i.e. is nan or +/-inf). This function is used to check data validity upon replots, when the compiler flag QCUSTOMPLOT_CHECK_DATA is set.

bool QCP::isInvalidData ( double  value1, double  value2  )

inline

This is an overloaded function.

Checks two arguments instead of one.

void QCP::setMarginValue ( QMargins &  margins, QCP::MarginSide  side, int  value  )

inline

Sets the specified side of margins to value

See Also

getMarginValue

int QCP::getMarginValue ( const QMargins &  margins, QCP::MarginSide  side  )

inline

Returns the value of the specified side of margins. If side is QCP::msNone or QCP::msAll, returns 0.
