## 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.

## Constructor & Destructor Documentation

## ◆ QCPGraphData() [1/2]

QCPGraphData::QCPGraphData | ( |  | ) |

Constructs a data point with key and value set to zero.

## ◆ QCPGraphData() [2/2]

QCPGraphData::QCPGraphData | ( | double | key,
|  | double | value )

Constructs a data point with the specified key and value.

## Member Function Documentation

## ◆ 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.

## ◆ fromSortKey()

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.

## ◆ sortKeyIsMainKey()

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.

## ◆ 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.

## ◆ 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.

## ◆ 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.
