# Enum: AxisScale 




_How an axis maps values to distance. Part of what a panel claims, not decoration: a straight line on a log axis is a power law, and the same points on a linear axis are not._

## Permissible Values
| Value | Meaning | Description |
| --- | --- | --- |
| linear | None | Equal value, equal distance |
| log | None | Equal ratio, equal distance |
| symlog | None | Logarithmic either side of zero, linear across it, so a quantity that changes... |
| logit | None | For a probability: stretches both ends of [0, 1] so behaviour near 0 and 1 is... |




## Slots

| Name | Description |
| ---  | --- |
| [xscale](../slots/xscale.qmd) | How the x axis maps values to distance |
| [yscale](../slots/yscale.qmd) | How the y axis maps values to distance |

    description: Equal value, equal distance.
  log:
    text: log
    description: Equal ratio, equal distance. Refuses non-positive data.
  symlog:

    description: Logarithmic either side of zero, linear across it, so a quantity
      that changes sign still spans decades.
  logit:
    text: logit
    description: 'For a probability: stretches both ends of [0, 1] so behaviour near
      0 and 1 is visible.'
