What is an Excel Chart?

An Excel chart visually represents data from a spreadsheet, facilitating the understanding of trends, models, and relationships. It simplifies data interpretation and communication by using visuals such as bars, lines, and slices, rather than analyzing numerical rows and columns.

• Visual Clarity: Enhances the understanding of complex data quickly.
• Customisable: Allows adjustments of colours, labels, titles, and chart types.
• Interactive: Enables filtering and dynamic updates using pivot tables or slicers.
• Versatile: Applicable in business reports, academic analysis, financial  dashboards, and more.

Types of Charts in MS Excel

Excel offers a variety of chart types, each with distinct functions. This document identifies the 12 most frequently used charts and illustrates their roles in data analysis and reporting.

1) Column Chart

Column charts use vertical bars to display data across categories. They are best for showing comparisons where each bar represents a different category or time period.

a) Comparing discrete categories

b) Showing growth or decline

c) Ranking items side by side

2) Bar Chart

Bar charts use horizontal bars instead of vertical ones, making them useful when category labels are long.

Best for:

a) Comparing large sets of categories

b) Displaying long labels clearly

c) Ranking values side by side

3) Line Chart

Line charts connect data points with a line to show changes over time.

Best for:

a) Tracking trends

b) Forecasting

c) Showing continuous data

Example:

A retailer might use a line chart to track monthly online sales across a year.

4) Scatter Chart (XY Chart)

Scatter charts plot individual data points to show relationships between two variables.

Best for:

a) Identifying correlations

b) Spotting patterns

c) Scientific/analytical data

Example:

A marketing team might analyse the relationship between advertising spend and sales revenue.

5) Pie Chart

Pie charts indicate data as slices of a circle, representing proportions of the total.

Best for:

a) Showing percentages

b) Part-to-whole analysis

c) Limited categories (up to 6)

Example:

A company might use a pie chart to show the share of total expenses by department.

6) Doughnut Chart

Doughnut charts are like pie charts but allow multiple data series in concentric rings.

Best for:

a) Showing proportions with more detail

b) Comparing categories in layers

c) Displaying part-to-whole relationships

Example:

A retailer might use a doughnut chart to show sales distribution by region and product category.
