Bar-Column Charts are usually used to demonstrate how a range of a continuous value changes due to
another variable or to show the difference in ranges of the same parameter values between categories.
This Chart has an only Bar series that shows the average time of a cell phone battery getting discharged.
There are eight cell phone models of different distributors mentioned and described; these are categories
spread along the vertical X-Axis. The time in hours is situated on the horizontal Y-Axis. Tooltips are in
single mode and they show all the information about the current point: the highest, the lowest values and
the cell phone model.
