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.

◆ 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.

◆ PlottingHint
enum QCP::PlottingHint |
Defines plotting hints that control various aspects of the quality and speed of plotting.
- See also
- QCustomPlot::setPlottingHints
Enumerator | |
---|---|
phNone |
|
phFastPolylines |
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 |
This is set by default to prevent the plot from freezing on fast consecutive replots (e.g. user drags ranges with mouse). |
phCacheLabels |
|
Definition at line 234 of file qcustomplot.h.
◆ ResolutionUnit
enum QCP::ResolutionUnit |
Defines the different units in which the image resolution can be specified in the export functions.
Enumerator | |
---|---|
ruDotsPerMeter | Resolution is given in dots per meter (dpm) |
ruDotsPerCentimeter | Resolution is given in dots per centimeter (dpcm) |
ruDotsPerInch | Resolution is given in dots per inch (DPI/PPI) |
Definition at line 164 of file qcustomplot.h.
◆ 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. |
Definition at line 268 of file qcustomplot.h.
◆ 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:
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. |
Definition at line 292 of file qcustomplot.h.
◆ 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.
Definition at line 185 of file qcustomplot.h.
Function Documentation
◆ getMarginValue()
|
inline |
Returns the value of the specified side of margins. If side is QCP::msNone or QCP::msAll, returns 0.
- See also
- setMarginValue
Definition at line 346 of file qcustomplot.h.
◆ isInvalidData() [1/2]
|
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.
Definition at line 305 of file qcustomplot.h.
◆ isInvalidData() [2/2]
|
inline |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Checks two arguments instead of one.
Definition at line 315 of file qcustomplot.h.
◆ setMarginValue()
|
inline |
Sets the specified side of margins to value
