Detailed Description
Provides a table class holding all data values that are to be used in a chart.
By subclassing KDChartTableDataBase you may provide your own methods to access data stored somewhere else instead of using the setCell function to move them into KD Chart's cells.
- Note
- See the files in doc/tutorial/step07/ for a sample implementation you might want to use as starting-point for your own data handling class.

◆ KDCHART_NEG_INFINITE
| #define KDCHART_NEG_INFINITE -DBL_MAX |
Use special value KDCHART_NEG_INFINITE to indicate negative infinite values.
If your own table class (derived from KDChartTableDataBase) does not store your negative infinite values as KDCHART_NEG_INFINITE please make sure to reimplement
- See also
- isNegInfinite() accordingly.
