Protected Member Functions

virtual bool isDataAcceptable ()
- Protected Member Functions inherited from Filter
QwtPlotCurve * addResultCurve (double *x, double *y)
 Adds the result curve to the target output plot window. Creates a hidden table and frees the input data from memory.
virtual void calculateOutputData (double *X, double *Y)
 Calculates the data for the output curve and store it in the X an Y vectors.
int curveIndex (const QString &curveTitle, Graph *g)
 Performs checks and returns the index of the source data curve if OK, -1 otherwise.

Private Member Functions

void init ()
