# Polar Plots

To switch to graphing with polar coordinates, type:
To switch back to Cartesian coordinates, type:
In polar mode, the independent variable *x* corresponds to the
angle, or *theta* noramally used for polar plots. Polar plots are
always plotted in a rectangular box, to change the size of the graph,
use the **set yrange** command. This will change both the
horizontal and vertical range. For an example, consider the following:
To change the displayed range so their is extra space around the
graph, type:

Note that this would leave the **yrange** set to [-4:4] for
subsequent plots. To turn autoscaling back on, use the following:

The default for interpretation of the angle is radians. To switch this
value, you can use one of the following:
**set angles degrees****set angles radians**

## 3D Polar coordiantes

GnuPlot supports the 3D equivalent of polar coordinates, spherical and
cylindrical coordinates, are only available for 3D **data**
plots. For information on them, see **help set mapping**.
