How does a bar chart make it easier to see the pattern in a data?

Bar graph is a visual tool that uses bars to compare data among categories

Explanation:

Bar charts compares the values between the categories. It is one of the easy method to check whether the data is discrete or continuous where discrete data is counted as number of political parties and continuous is measured in height or sales.

If the data has more than one value per category, a stacked or grouped bar charts allows you to see individual values and compare categories.

The stacked bar chart is ideal for comparing the sum of the components of each group. The stacked bar chart is not useful for comparing totals because the present of all respondents adds up to 100% roughly for every category.
