# Plot Bar Graph
|
||||
|
||||
Displays a vertical bar graph based on the value and high value.
|
||||
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.

### Parameters
|
||||
|
||||
* value: [Number](/reference/types/number) , high : [Number](/reference/types/number) displays a vertical bar graph based on the value and high value
|
||||
* `value` is a [Number](/reference/types/number) that means what you are measuring or trying to show. For example, if you are measuring the temperature of ice with the BBC micro:bit, `value` might be 0 because the temperature might be 0 degrees centigrade.
|
||||
* `high` is a [Number](/reference/types/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](/reference/input/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.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
let a = input.acceleration(Dimension.X);
