f(x)= | The coefficients of the function given as a decimal
or in form of a fraction. Empty fields will be interpreted as zero. |

Scan start | The point where the scan shall begin. Characteristic points, that
are not in the interval [start,end] remain undiscovered. |

Scan end | The point where the scan shall end. Characteristic points, that
are not in the interval [start,end] remain undiscovered. |

Step | The step rate in which the interval will be scanned. If it is chosen too big, some
characteristic points may remain undiscovered. If it is too small, performance may suffer. |

Epsilon | If a y-value falls below this threshold a zero approximation via
Newton will start. |

Plot start | The leftmost x-value of the plot. |

Plot end | The rightmost x-value of the plot. |

f-boxes | Selects the functions, that will be plotted. |

Apply | Starts the scan. |

New | Clears the input masks, so that a new function can be entered. |
