# Plot Acceleration
The ``||led:plot bar graph||`` uses the screen to display magnitude of a value (positive or negative).
This is a great tool to understand the data returned by sensors... like the accelerometer.
## Acceleration
This example plots the acceleration in the ``x`` dimension on the LEDs.
```blocks
basic.forever(() => {
led.plotBarGraph(
input.acceleration(Dimension.X),
0
)
})
```
## Console
Click on the ``||Show Console||`` button to see a time chart of the value passed in the block.
## Maximum value
If you specify the maximum value, the block can do a better job at displaying the data.
For example, we can tell the block that we don't expect values beyond 1000 mg.
```blocks
basic.forever(() => {
led.plotBarGraph(
input.acceleration(Dimension.X),
1000
)
})
```
## Other sensors
You can use this block for pretty much any data. Try it out! We pass the light level to play with the light sensor.
```blocks
basic.forever(() => {
led.plotBarGraph(
input.lightLevel(),
0
)
})
```
