Public Methods

 FunctionGraph (QWidget *parent=0, const char *name=0)
 ~FunctionGraph ()
int execMathFunction (const char *id)
 Execute an installed MathFunction with the given id.

virtual void installMathFunctions ()
 Implement this function to install any MathFunction's to a specific class.

virtual int getGraphType () const

Protected Methods

virtual const char * independent_vars ()
 Returns a list of independent variables for the expression which, when there are more than one, are seperated by commas.

virtual const char * dependent_var (int=0)
 Returns the dependent variable.

Member Function Documentation

virtual const char* FunctionGraph::dependent_var (  int    = 0 )  [inline, protected, virtual]
 

Returns the dependent variable.

The argument 'i' is used to get each dependent variable if there are more than one ( i.e. parametric graph ).

Implements ExpressionGraph.

Definition at line 46 of file functiongraph.h.

void FunctionGraph::installMathFunctions (    )  [virtual]
 

Implement this function to install any MathFunction's to a specific class.

A math function should be added by calling addMathFunction( MathFunction*, const char * id ) Example: addMathFunction(new DistanceMathFunction(this), "Distance");

Reimplemented from BasicGraph.

Definition at line 37 of file functiongraph.cpp.
