What is Bar Chart?
A bar chart, also known as a bar graph, is a visual representation of data using rectangular bars. Each bar represents a specific category or item, and the length of the bar corresponds to the value or frequency of that category. Bar charts are commonly used to compare and display data in an easily understandable format.
What are the types of Bar Chart?
There are several types of bar charts, each with its own purpose and suitability for different types of data analysis. Some common types of bar charts include:
Vertical Bar Chart: This is the most common type of bar chart, where the bars are plotted vertically and represent the data values.
Horizontal Bar Chart: In this type of bar chart, the bars are plotted horizontally and represent the data values.
Stacked Bar Chart: This type of chart is used to show the composition of a whole by stacking the bars on top of each other.
Grouped Bar Chart: This chart displays multiple bars for each category, allowing easy comparison between different groups of data.
Clustered Bar Chart: Similar to a grouped bar chart, but with bars grouped together side by side for each category.
