Set Plot Coordinate System

Description

 • The default coordinate system for all two dimensional plotting commands is the cartesian coordinate system.  The coords option allows the user to alter this coordinate system.  The alternate choices are:  bipolar, cardioid, cassinian, elliptic, hyperbolic, invcassinian, invelliptic, logarithmic, logcosh, maxwell, parabolic, polar, rose, and tangent.
 • See coords for a full description of each of these coordinate systems.
 • All coordinate systems are also valid for parametrically defined 2-D plots with the same interpretations of the coordinate system transformations.
 • With most plotting commands, Cartesian axes are displayed by default, regardless of the coordinate system used.  The plots[polarplot] command displays polar axes by default. You can also obtain polar axes by adding the axiscoordinates=polar option along with the coords=polar option.

Examples

 > $\mathrm{plot}\left(\mathrm{sin}\left(x\right),x=0..2\mathrm{Pi},\mathrm{coords}=\mathrm{polar}\right)$
 > $\mathrm{plot}\left(\mathrm{sin}\left(x\right),x=0..2\mathrm{Pi},\mathrm{coords}=\mathrm{polar},\mathrm{axiscoordinates}=\mathrm{polar}\right)$
 > $\mathrm{plot}\left(\mathrm{sin},0..2\mathrm{Pi},\mathrm{coords}=\mathrm{bipolar}\right)$

The command to create the plot from the Plotting Guide is

 > $\mathrm{plot}\left(\mathrm{ln}\left(x\right),x=0..2\mathrm{Pi},\mathrm{coords}=\mathrm{elliptic},\mathrm{view}=\left[-4..8,-3..1\right]\right)$
