|
|
|
This class implements an intelligent plotting algorithm for functions. It starts by sampling
|
|
the function at minSamples positions. Then each function interval is bisected recursively if
|
|
necessary. To do so the function is evaluated at the mid point and the slopes \f$ \alpha_{\mbox{left}} \f$
|
|
and \f$ \alpha_{\mbox{right}} \f$ of the two linear segments are compared. the midpoint is added
|
|
to the graph if \f[ \left|\alpha_{\mbox{right}}-\alpha_{\mbox{left}}\right|>\mbox{slopeTolerance} \f]
|
|
In addition all sampling points except minimum and maximum are beeing shifted by a random fraction their
|
|
distance to the other points. This helps to prevent beats when sampling periodic functions.
