Detailed Description

Holds the data of one single data point for QCPGraph.

The stored data is:

• key: coordinate on the key axis of this data point (this is the mainKey and the sortKey)
• value: coordinate on the value axis of this data point (this is the mainValue)

The container for storing multiple data points is QCPGraphDataContainer. It is a typedef for QCPDataContainer with QCPGraphData as the DataType template parameter. See the documentation there for an explanation regarding the data type's generic methods.

Member Function Documentation

fromSortKey()

static QCPGraphData QCPGraphData::fromSortKey ( double  sortKey )

inlinestatic

Returns a data point with the specified sortKey. All other members are set to zero.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

Definition at line 5139 of file qcustomplot.h.

mainKey()

double QCPGraphData::mainKey ( ) const

inline

Returns the key member of this data point.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

Definition at line 5142 of file qcustomplot.h.

mainValue()

double QCPGraphData::mainValue ( ) const

inline

Returns the value member of this data point.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

Definition at line 5143 of file qcustomplot.h.

sortKey()

double QCPGraphData::sortKey ( ) const

inline

Returns the key member of this data point.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

Definition at line 5138 of file qcustomplot.h.

sortKeyIsMainKey()

static static bool QCPGraphData::sortKeyIsMainKey ( )

inlinestatic

Since the member key is both the data point key coordinate and the data ordering parameter, this method returns true.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.

Definition at line 5140 of file qcustomplot.h.

valueRange()

QCPRange QCPGraphData::valueRange ( ) const

inline

Returns a QCPRange with both lower and upper boundary set to value of this data point.

For a general explanation of what this method is good for in the context of the data container, see the documentation of QCPDataContainer.
