\class KDChartTableDataBase KDChartTableBase.h
|
|
|
|
\brief Encapsulates all data values that are to be used in a chart.
|
|
|
|
|
|
|
|
\note To create your data table you would <em>not</em> use a
|
|
|
|
\c KDChartTableDataBase but instantiate the class \c KDChartTableData.
|
|
|
|
The \c KDChartTableData class is an auxiliary class: depending on your
|
|
|
|
TQt version it will be mapped onto a \c KDChartVectorTableData or onto
|
|
|
|
a \c KDChartListTableData both of which are derived from
|
|
|
|
\c KDChartTableDataBase and implement all of its functions.
|
|
|
|
Thus you would create a table of 3 datasets with 25 cells each like this:
|
|
|
|
\verbatim
|
|
|
|
|
|
|
|
KDChartTableData myData( 3, 25 );
|
|
|
|
|
|
|
|
\endverbatim
|
|
|
|
|
|
|
|
Data values may be specified via \c setCell().
|
|
|
|
Cell specific properties may be specified via \c setCellProp().
|
|
|
|
|
|
|
|
You may adjust or modify your table like this:
|
|
|
|
|
|
|
|
\li Entering the data can be done either manually using \c setCell()
|
|
|
|
or by passing a TQTable to the \c importFromQTable() function.
|
|
|
|
|
|
|
|
\li Performance of KD Chart can be increased by specifying the number
|
|
|
|
of rows and or the number of columns actually used: \c setUsedRows()
|
|
|
|
and/or \c setUsedCols() prevents KD Chart from iterating over thousands
|
|
|
|
of empty rows/cols that might follow your data cells in case your
|
|
|
|
table is much bigger than needed.
|
|
|
|
|
|
|
|
\li In case you want to increase your table's size without using the
|
|
|
|
data stored in it please call the \c expand() function with the new
|
|
|
|
total number of rows and cells.
|
|
|
|
|
|
|
|
\li Accessing one data cell is possible via \c cellCoord()
|
|
|
|
and via \c cellProp(),
|
|
|
|
e.g. you might assign a special property set ID to all cells with a
|
|
|
|
future absicssa axis value:
|
|
|
|
\verbatim
|
|
|
|
|
|
|
|
const TQDateTime currentTime( TQDateTime::currentDateTime() );
|
|
|
|
for( int iCell = 0; iCell < usedValues; ++iCell ){
|
|
|
|
KDChartData& cell = myData.cell( 0, iCell );
|
|
|
|
// assign special property set ID if X value is in the future
|
|
|
|
if( cell.isDateTime( 2 ) && cell.dateTimeValue( 2 ) > currentTime )
|
|
|
|
cell.setPropertySet( idProp_FutureValues );
|
|
|
|
}
|
|
|
|
|
|
|
|
\endverbatim
|
|
|
|
|
|
|
|
\note All of the other functions provided by KDChartTableDataBase are
|
|
|
|
either used internally by KD Chart or they are const methods
|
|
|
|
returning some usefull figures like the sum of all values in a row...
