-# Plot Bar Graph
+# 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.
+Display a bar graph for a number value.
 
 ```sig
 led.plotBarGraph(2, 20);
 ```
 
+A bar graph is a kind of chart that shows numbers as lines with different lengths.
+
 ## Parameters
 
-* ``value`` is a [number](/types/number) that means what you
+* **value**: a [number](/types/number) that is the value of what you
   are measuring or trying to show. For example, if you are measuring
   the temperature of ice with the @boardname@, ``value`` might be `0`
-  because the temperature might be 0 degrees centigrade.
-* ``high`` is a [number](/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.
+  if the temperature is 0 degrees Celsius.
+* **high**: a [number](/types/number) that is the highest
+  possible number (maximum) that the **value** parameter can be. The lines in the bar graph will reach their highest point when **value** reaches this number. If **high** is `0`, then the largest value recently plotted is used as the maximum.
 
 ## Example: chart acceleration
 
-This program shows a bar graph of the [acceleration](/reference/input/acceleration) 
+Show a bar graph of the [acceleration](/reference/input/acceleration) 
 in the `x` direction of the @boardname@.
 The @boardname@'s `x` direction is from left to right (or right to left).
-The more you speed up moving the @boardname@ 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.
+The faster you move the @boardname@ in this direction,
+the taller the lines in the bar graph will be. The **high** paramter is `1023` which sets the highest possible value of acceleration to show.
