# Polar Options

When you click on the Polar Options button you will see the dialog where you can adjust the parameters for the radii and arcs drawn in the domain.

Notes:

- If the minimum radius is `0.0` and you specified to draw `10` arcs, say, you will only see `9` arcs because the first arc has radius `0` and is not drawn.
- You can use only numbers, not constants like Pi or expressions such as Pi - atan(1) in the text fields.
