# Excel Tutorial: How To Change Interval In Excel Graph

## Introduction

Creating graphs and charts in Excel is a powerful way to visually represent data. However, sometimes the default intervals on the axes may not accurately reflect the range of data, leading to a misleading visual representation. In this tutorial, we will explore the importance of changing intervals in Excel graphs and provide a brief overview of the steps to do so.

## Key Takeaways

• Changing intervals in Excel graphs is important for accurate data representation
• Analyzing and understanding the data is crucial before adjusting interval settings
• Choosing the appropriate graph type is essential for effective visualization
• Customizing interval values can improve precision in data interpretation
• Experimenting with different interval settings can lead to better data visualization

## Understanding the Data

Before you can effectively change the interval in an Excel graph, it's essential to have a solid understanding of the data that will be plotted. This involves analyzing the data and identifying its range and distribution.

A. Analyzing the data that will be plotted on the graph

Take the time to thoroughly analyze the data that will be used in the graph. This includes reviewing the values, identifying any patterns or trends, and understanding the significance of the data points.

B. Identifying the range and distribution of the data

Once you have a clear understanding of the data, it's important to identify the range and distribution of the values. This will help determine the appropriate intervals for the graph and ensure that the data is accurately represented.

## Selecting the Graph Type

When creating a graph in Excel, it's important to choose the appropriate graph type for the specific data you are trying to visualize. Different types of data are best represented by different types of graphs, and selecting the right type can make a big difference in how effectively the data is communicated.

Choosing the appropriate graph type for the data

Bar graphs are typically used to compare different groups or categories of data, while line graphs are used to show trends over time. Scatter plots are used to show the relationship between two variables, and pie charts are used to show the proportions of a whole. It's important to consider what type of data you have and what you want to communicate before selecting a graph type.

Considering the impact of interval changes on different graph types

### Bar Graphs

• Changing the interval in a bar graph can impact the width of the bars and the spacing between them, which can affect how the data is interpreted.
• For example, if you change the interval from monthly to quarterly in a bar graph showing sales data, the bars will become wider and the spacing between them will increase, potentially making it more difficult to compare sales between different months.

### Line Graphs

• Changing the interval in a line graph can impact the smoothness of the lines and the clarity of the trends being shown.
• For example, if you change the interval from daily to weekly in a line graph showing stock prices, the lines will become less smooth and it may be harder to see the day-to-day fluctuations in the stock prices.

### Scatter Plots

• Changing the interval in a scatter plot can impact the density of the data points and the clarity of any patterns or relationships being shown.
• For example, if you change the interval from hourly to daily in a scatter plot showing temperature and ice cream sales, the data points will be more spread out and it may be harder to see any correlations between temperature and sales.

Considering the impact of interval changes on different graph types is essential for creating clear and effective visualizations of your data in Excel.

## Adjusting Axis Intervals

Excel allows you to easily adjust the intervals on your graph's x and y-axis to better display your data. By customizing the intervals, you can ensure that your graph accurately represents your data without any distortion.

### Accessing the axis options in Excel

To begin adjusting the interval settings on your graph, you'll need to access the axis options in Excel.

• Select your graph: Open your Excel workbook and navigate to the worksheet containing your graph. Click on the graph to select it.
• Access the Format Axis pane: With the graph selected, navigate to the "Chart Tools" section in the Excel ribbon. Click on the "Format" tab, and then select "Format Selection" to open the Format Axis pane.

### Modifying the interval settings for the x and y-axis

Once you have accessed the Format Axis pane, you can proceed to modify the interval settings for the x and y-axis.

• Adjust the interval for the x-axis: In the Format Axis pane, click on the "Axis Options" tab. Here, you can adjust the interval for the x-axis by entering a specific number in the "Major unit" field. This will determine the spacing between each interval on the x-axis.
• Modify the interval for the y-axis: Similarly, you can adjust the interval for the y-axis by entering a specific number in the "Major unit" field under the "Axis Options" tab. This will determine the spacing between each interval on the y-axis.

By following these steps, you can easily customize the interval settings on your Excel graph to ensure that it accurately represents your data.

## Customizing Interval Values

When creating graphs in Excel, it’s important to customize the interval values to accurately represent the data. By setting specific interval values, you can achieve more precision in your visualizations and gain valuable insights into the trends and patterns within your data.

### A. Setting specific interval values for more precision

• Accessing Axis Options: To set specific interval values, start by selecting the graph in Excel and accessing the Axis Options. This will allow you to modify the interval values for the horizontal and vertical axes.
• Entering Custom Interval: Within the Axis Options, you can enter custom interval values that align with the scale of your data. This customization will ensure that the graph accurately reflects the nuances within your dataset.
• Applying Changes: After entering the custom interval values, apply the changes to see the updated graph with more precise interval markings that better represent the underlying data.

### B. Exploring the impact of different interval settings on data visualization

By exploring different interval settings, you can gain insights into how these adjustments impact the visualization of your data.

• Effect on Trend Analysis: Different interval settings can highlight varying trends within the data, making it easier to discern patterns and fluctuations.
• Enhanced Data Clarity: Adjusting interval values can lead to a clearer representation of the data, especially when dealing with large datasets or complex information.
• Improved Comparisons: Changing interval settings can enhance the ability to compare data points and identify correlations or disparities more effectively.

## Formatting the Graph

When creating a graph in Excel, it's important to not only present the data accurately, but also to ensure that the graph is visually appealing and easy to interpret. One way to enhance the visual appeal of the graph is by adjusting the interval settings to improve clarity and readability.

A. Enhancing the visual appeal of the graph
• Choose an appropriate chart type and style that best represents the data.
• Modify the colors, borders, and styles of the graph elements to make them visually appealing.
• Consider adding titles, labels, and legends to provide context and clarity to the graph.
• Adjust the size and position of the graph to ensure it fits well within the document or presentation.

B. Ensuring clarity and readability with the new interval settings
• Open the Excel file containing the graph that you want to modify.
• Select the graph and navigate to the "Chart Tools" section on the Excel ribbon.
• Click on the "Format" tab to access various formatting options for the graph.
• Find the interval settings for the graph and adjust them to better represent the data.
• Test different interval settings to find the most appropriate one for your graph.
• Ensure that the intervals are clearly labeled and consistent throughout the graph.

## Conclusion

Changing the interval in Excel graphs is crucial for accurate data representation. By adjusting the interval, you can effectively display trends and patterns in your data. It's important to experiment with different interval settings to see which one best suits your data and aids in clearer interpretation. Don't hesitate to play around with the options and find the perfect interval for your Excel graph.
