GrADS Command: set ylevs

## set ylevs

`set ylevs lev1 lev2 ... levN`

Allows the user to specify each individual labeled tick mark for the Y-axis.

### Usage Notes

1. Reset by clear, but not display.

2. `set ylevs` will override the tick mark interval specified with the `set ylint` command.

3. If you use `set yaxis` to specify labeled tick marks and also invoke `set ylevs`, then the tick marks `lev1 ... levN` specified with `set ylevs` will appear if they fall within the `start` and `end` range specified in the `set yaxis` command.

4. This command does not apply to a date/time axis.
