Public Methods   MinimumFunction (BasicGraph *, int)   ~MinimumFunction () Protected Methods void  calculate_and_draw (QPainter *)   When creating a math function subclass, overwrite this function to calculate and then draw whatever visual you wish using the given QPainter. void  draw_stored (QPainter *)   When creating a math function subclass, overwrite this function with a function to more quickly draw the result of the function. Detailed Description Author: Fungmeista Note: This numerically calculates the minimum point on the interval. This means that for non-continuous functions it will not return correct values of since the minimum may not be defined. Definition at line 28 of file minimumfunction.h. Member Function Documentation void MinimumFunction::calculate_and_draw (  QPainter *    painter )  [protected, virtual]   When creating a math function subclass, overwrite this function to calculate and then draw whatever visual you wish using the given QPainter. You should also call the function setResult() inside this function and pass to it a string that you wish to be displayed as the result of the function. Reimplemented from MathFunction. Definition at line 32 of file minimumfunction.cpp. References draw_stored(), MathFunction::expression, MathFunction::setResult(), and MathFunction::toGraphXCoord(). void MinimumFunction::draw_stored (  QPainter *    painter )  [protected, virtual]   When creating a math function subclass, overwrite this function with a function to more quickly draw the result of the function. For example, if calculate_and_draw calculates many points, these can be saved and drawn in draw_stored instead of recalculating them. Reimplemented from MathFunction.
