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
valueis a 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,valuemight be 0 because the temperature might be 0 degrees centigrade.highis a Number that means the highest possible number that thevalueparameter 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)
