<jhelp> In addition to entering functions and selecting options on the toolbar, you can specify in more detail what type of curves are drawn in the domain and hence mapped to the range.

> | The Global Options let you adjust the view rectangle of the domain and range (the minimum and maximum values), the number of points to use when drawing curves (more points mean smoother curves), as well as the line thickness and background color.
> | The Rectangle Options let you adjust the number of horizontal and/or vertical lines to be drawn in the domain
> | The Polar Options let you adjust the parameters for the circles, arcs, and rays drawn in the domain

Note that once the options dialog is open you can switch between the different modes by clicking on one of the tabs. For details, please refer to the corresponding help sections. </jhelp>
