class GroupedBarChart: public Chart
Implements a grouped bar chart. A grouped bar chart contains a set of grouped bar data elements, grid lines, two axes and a headline label.
Inherits from Chart.
| GroupedBarChart | Implements a grouped bar chart. |
| Functions | |
| GroupedBarChart | Initializes the object. |
| ~GroupedBarChart | Releases all allocated resources. |
| Draw | Draws the chart. |
| DrawLabels | Draws the label assigned to the chart. |
| ChangePosition | Unused function. |
| ChangeAlpha | Unused function. |
| GetConnectedDataElementByDataGroup | Returns the grouped bar which represents the given data group. |
| GetConnectedBar | Returns the bar data element which represents the given data entry. |
| GetAllBars | Returns a vector containing all visible (not filtered) bars of all grouped bars of the chart. |
| GetVisibleDataGroups | Returns a vector containing all visible data groups of the given data groups, i.e. |
| ContainsDataEntry | Lookup function which checks the existence of a given data entry pointer in a given vector. |
void Draw( QPainter * pPainter )
Draws the chart. Inherited from AlterableObject.
| pPainter | The QPainter object that shall be used for painting. |
void DrawLabels( QPainter * pPainter )
Draws the label assigned to the chart. Inherited from AlterableObject.
| pPainter | The QPainter object that shall be used for painting. |
void ChangePosition( float fDeltaLeft, float fDeltaTop, float fDeltaBottom )
Unused function. Inherited from AlterableObject.
| fDeltaLeft | Unused parameter. |

void ChangeAlpha( float fDeltaAlpha )
Unused function. Inherited from AlterableObject.
| fDeltaAlpha | Unused parameter. |
DataElement* GetConnectedDataElementByDataGroup( DataGroup * pDataGroup )
Returns the grouped bar which represents the given data group. If no such grouped bar exists, NULL is returned.
| pDataGroup | Pointer to the data group to be searched. |
The grouped bar which represents the given data group if present, else NULL.
DataElement* GetConnectedBar( DataEntry * pDataEntry )
Returns the bar data element which represents the given data entry. If no such bar exists among all grouped bars, NULL is returned.
| pDataEntry | Pointer to the data entry to be searched. |
The bar data element which represents the given data entry if present, else NULL.
std::vector<DataGroup*> GetVisibleDataGroups( std:: vector<DataGroup*> vAllDataGroups )
Returns a vector containing all visible data groups of the given data groups, i.e. all data groups with at least one unfiltered data entry.
| vAllDataGroups | A vector containing all data groups of a data set. |
A vector containing all visible data groups of the given data groups.
bool ContainsDataEntry( std:: vector<DataEntry*> vDataEntries, DataEntry * pDataEntry )
Lookup function which checks the existence of a given data entry pointer in a given vector.
| vDataEntries | A vector of data entry pointers. |
| pDataEntry | A data entry pointer to be searched. |
A boolean value indicating if the vector contains the data entry.
Implements a grouped bar chart.
