# Unplot
|
|
|
|
Turn off the LED light you say on the [LED screen](/device/screen).
|
|
|
|
```sig
|
|
led.unplot(0,0)
|
|
```
|
|
|
|
## ~hint
|
|
|
|
Use [plot](/reference/led/plot) to turn **on** an LED.
|
|

|
## Parameters
|
|
|
|
* ``x`` is a [number](/types/number) that means the
|
|
horizontal spot on the LED screen (from left to right: 0, 1, 2, 3,
|
|
or 4)
|
|
* ``y`` is a [number](/types/number) that means the vertical
|
|
spot on the LED screen (from top to bottom: 0, 1, 2, 3, or 4)
|
|
|
|
If a parameter is [out of bounds](/reference/out-of-bounds) (a value
|
|
other than 0 to 4), then this function will do nothing.
|
|
|
|
## ~hint
|
|
|
|
The LED screen is a solid square of LEDs with five LEDs on each side.
|
|
To learn more about how you number the LEDs with ``x`` and ``y``
|
|
coordinates, see [LED screen](/device/screen).

|
## Example: Center off
|
|
|
|
This program shows a picture on the LED screen, and then turns off the center LED with `unplot`.
|
|
|
|
```blocks
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. . # . .
|
|
# # # # #
|
|
. . # . .
|
|
. . # . .
|
|
`)
|
|
basic.pause(500)
|
|
led.unplot(2, 2)
|
|
```
|
|
|
|
## ~hint
|
|
|
|
Use the [point](/reference/led/point) function to find out if an LED is
|
|
on or off.
