Understanding Figure Labeling in Research Papers

In academic writing, properly labeling figures is crucial for effective communication of information. Figures—whether they are graphs, charts, or images—must be clearly titled and referenced in the text to help readers easily understand the data presented. Below are three diverse, practical examples of labeling figures in a research paper.

Example 1: Bar Graph Representing Survey Results

Context: This example illustrates how to label a bar graph that displays survey results on student study habits.

Figure 1: Student Study Habits by Time of Day
This bar graph shows the distribution of study habits among college students based on the time of day they prefer to study. The X-axis represents different times of day (Morning, Afternoon, Evening), and the Y-axis indicates the percentage of students who study during those times. Each bar is color-coded to represent different fields of study (e.g., Science, Arts, Engineering).

• Notes: Ensure that the figure is numbered sequentially (e.g., Figure 1, Figure 2) as it appears in the paper. The title should be bold and descriptive to provide immediate context.

Example 2: Pie Chart Showing Budget Allocation

Context: This example demonstrates how to label a pie chart that outlines the budget allocation for a research project.

Figure 2: Budget Allocation for Research Project
This pie chart illustrates the percentage of the total budget allocated to various components of the research project, including Personnel (40%), Equipment (25%), Supplies (20%), and Miscellaneous (15%). Each section of the pie chart is labeled with both the percentage and the corresponding category, making it easy to discern how funds are distributed.

• Notes: When creating pie charts, consider using contrasting colors to enhance visibility. Each section should remain clear, and the title should succinctly convey the chart’s purpose.

Example 3: Line Graph Showing Temperature Change Over Time

Context: This example provides a method for labeling a line graph tracking temperature changes over a year.

Figure 3: Monthly Average Temperature Changes in 2023
This line graph depicts the average monthly temperatures recorded throughout the year 2023. The X-axis lists the months (January to December), while the Y-axis indicates the average temperature in degrees Celsius. The graph includes a legend indicating the different cities represented in the data (e.g., City A, City B). Each point on the line is marked for clarity, and a smooth line connects these points to show trends.

• Notes: Including a legend is particularly useful when multiple datasets are presented in one graph. The figure should be referenced in the text (e.g., “As shown in Figure 3...”) to maintain clarity and connection with the written content.
