Question

how will i explain double bar graph....?

Answer 1

We can use a double bar graph to compare two data groups. A double bar graph has two axes. The x-axis of a double bar graph shows the categories being compared, and the y-axis represents the scale. A scale is a set of numbers that represents the data organized into equal intervals

Answer 2

Double bar graph is a graphical way of explaining data/information of two thinga at the same time i.e. to compare two data groups.

You can even explain this way:

It helps us to compare or present more than one kind of information, situations or events instead of just one by using bars.
