## Values

| Name | Value | Description |
| --- | --- | --- |
| LogarithmicCartesian | 0 | Cartesian coordinates are mapped individually onto a logarithmic scale. |
| LogarithmicPolar | 1 | Cartesian coordinates are mapped jointly onto a logarithmic scale, preserving angles with respect to the origin. |
| ExponentialCartesian | 2 | Cartesian coordinates are mapped individually onto an exponential scale. |
| ExponentialPolar | 3 | Cartesian coordinates are mapped jointly onto a exponential scale, preserving angles with respect to the origin. |
