Detailed Description
The QCP Namespace contains general enums, QFlags and functions used throughout the QCustomPlot library.
It provides QMetaObject-based reflection of its enums and flags via QCP::staticMetaObject.
Enumeration Type Documentation
◆ 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.
| 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 |
| aeItems | 0x0040 Main lines of items |
| aeScatters | 0x0080 Scatter symbols of plottables (excluding scatter symbols of type ssPixmap) |
| aeFills | 0x0100 Borders of fills (e.g. under or between graphs) |
| aeZeroLine | 0x0200 Zero-lines, see QCPGrid::setZeroLinePen |
| aeOther | 0x8000 Other elements that don't fit into any of the existing categories |
| aeAll | 0xFFFF All elements |
| aeNone | 0x0000 No elements |
◆ ExportPen
| enum QCP::ExportPen |
Defines how cosmetic pens (pens with numerical width 0) are handled during export.

◆ Interaction
| 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 | |
|---|---|
| iNone | 0x000 None of the interactions are possible |
| 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, other layout elements,...) |
| iSelectPlottablesBeyondAxisRect | 0x100 When performing plottable selection/hit tests, this flag extends the sensitive area beyond the axis rect |
◆ MarginSide
| enum QCP::MarginSide |
◆ PlottingHint
| 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, thus is most effective for pen sizes larger than 1. It is only used for solid line pens. |
| phImmediateRefresh | 0x002 causes an immediate repaint() instead of a soft update() when QCustomPlot::replot() is called with parameter QCustomPlot::rpRefreshHint. 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. |
◆ ResolutionUnit
| enum QCP::ResolutionUnit |
◆ SelectionRectMode
Defines the behaviour of the selection rect.
| Enumerator | |
|---|---|
| srmNone | The selection rect is disabled, and all mouse events are forwarded to the underlying objects, e.g. for axis range dragging. |
| srmZoom | When dragging the mouse, a selection rect becomes active. Upon releasing, the axes that are currently set as range zoom axes (QCPAxisRect::setRangeZoomAxes) will have their ranges zoomed accordingly. |
| srmSelect | When dragging the mouse, a selection rect becomes active. Upon releasing, plottable data points that were within the selection rect are selected, if the plottable's selectability setting permits. (See data selection mechanism for details.) |
| srmCustom | When dragging the mouse, a selection rect becomes active. It is the programmer's responsibility to connect according slots to the selection rect's signals (e.g. QCPSelectionRect::accepted) in order to process the user interaction. |
◆ SelectionType
| enum QCP::SelectionType |
Defines the different ways a plottable can be selected. These images show the effect of the different selection types, when the indicated selection rect was dragged:
stNone | 
stWhole | 
stSingleData | 
stDataRange | 
stMultipleDataRanges |
| Enumerator | |
|---|---|
| stNone | The plottable is not selectable. |
| stWhole | Selection behaves like stMultipleDataRanges, but if there are any data points selected, the entire plottable is drawn as selected. |
| stSingleData | One individual data point can be selected at a time. |
| stDataRange | Multiple contiguous data points (a data range) can be selected. |
| stMultipleDataRanges | Any combination of data points/ranges can be selected. |
◆ SignDomain
| enum QCP::SignDomain |
Represents negative and positive sign domain, e.g. for passing to QCPAbstractPlottable::getKeyRange and QCPAbstractPlottable::getValueRange.
This is primarily needed when working with logarithmic axis scales, since only one of the sign domains can be visible at a time.
