# Plot Bar Graph

Displays a bar graph of the numbers you say. A bar graph is a kind of chart that shows numbers as lines with different lengths.

`led.plotBarGraph(2, 20);`

## Parameters

`value`

is a number that means what you are measuring or trying to show. For example, if you are measuring the temperature of ice with the micro:bit,`value`

might be`0`

because the temperature might be 0 degrees centigrade.`high`

is a number that means the highest possible number that the`value`

parameter can be. This number is also the tallest that the lines in the bar chart can be.

## Example: chart acceleration

This program shows a bar graph of the acceleration
in the `x`

direction of the micro:bit.
The micro:bit’s `x`

direction is from left to right (or right to left).
The more you speed up moving the micro:bit in this direction,
the taller the lines in the bar graph will be,
until they are as tall as the parameter `high`

says they can be.

```
basic.forever(() => {
let a = input.acceleration(Dimension.X);
led.plotBarGraph(a, 1023)
})
```
