Detailed explanation-3: -A bar diagram makes it easy to compare sets of data between different groups at a glance. The graph represents categories on one axis and a discrete value in the other. The goal is to show the relationship between the two axes. Bar charts can also show big changes in data over time.

Detailed explanation-4: -Double bar graph is useful for the comparison of data. Q. Bar graphs are usually used to represent ‘categorical data’ while histogram is usually used for ‘continuous data’.

Detailed explanation-5: -Multiple variable bar charts can be created from a single data file or from different data files. Typically, the X values (for vertical bars) are the same for each of the bar charts. However, the X values may be different between bar charts. When creating stacked bar charts, each row of data is considered a stack.
