Difference Between Charts and Graphs

Charts and graphs are too often used as synonyms. Both are important data visualizations, but they’ve got key differences.

Understanding Charts and Graphs

Each format for charts and graphs has its place, but the choice depends on the type of data you’re working with. The debate of chart vs graph comes down to the story that you seek to tell, as well.

Your points will land with the audience when you choose the best graphic for the occasion. What is the difference between a chart and a graph, and when should you choose each? Let’s find out.

Charts Versus Graphs (What’s the Difference?)

When you’re sharing information, it’s a great idea to use visuals. Trying to explain data through words alone can confuse an audience. By illustrating key points, you can bring your ideas to life in a stylish way that’s easy to understand.

Charts and graphs are the best way to do this. Both are data visuals that bring clarity to your message. Often, people use the terms chart and graph interchangeably, but in reality, there’s a difference.

What is a Chart?

A chart is a visual representation of data. They come in various forms and style data in different ways. Essentially, a chart converts your data into a visually digestible format, but it does not showcase how a change in one variable influences another variable.

What is a Graph?

Graphs, on the other hand, have a narrower definition and are excellent at showing how one variable affects another. They plot data on a grid with axes representing two variables.

Thinking to yourself “what is the difference between a chart and a graph?” Graphs are numerical in nature, whereas charts can represent broader sets of data.

Key Takeaways

Deciding whether to use a chart or a graph is the key first step in creating data visuals. Both serve as useful tools for visualizing data; the trick is selecting the one that works best for your needs.

Data visuals are meant to tell stories, and your visual aid should assist you in this task. Ensure that you use the simplest possible option to avoid confusing distractions.

When to Use a Chart

Now that we’ve explored the benefits of charts and graphs, let’s focus on charts and how to create them.

Why Choose a Chart?

Charts are your best bet if you need flexibility. They’re powerful tools for explaining how datasets fit together and relate to each other. Charts come in various styles and sizes, giving you the versatility needed to create visuals that accurately represent your data.

Chart Example List

Bar (Column) Charts
Bar/column charts illustrate data by placing each element in a rectangular bar, with bar length varying by size. They work well for plotting increasing or decreasing values.

Pie Charts
Pie charts are circular, representing how portions of a total dataset form the whole. They’re great for highlighting budget allocations or analyzing sales data.

Line Charts
Line charts connect individual data points with a line and are useful for illustrating trends in datasets.

How to Customize a Chart

Once you’ve selected your chart type, it’s time to customize it. For instance, if you run a business with multiple departments, you can use a pie chart to illustrate budget allocations.

To insert a chart in PowerPoint, navigate to the Insert tab, click on the Chart drop-down menu, and select your preferred chart type. A Microsoft Excel window will open to enter your data.

PowerPoint automatically updates your chart as you add data, making it easy to create an understandable visual.

When to Use a Graph

We’ve discussed charts; now let’s focus on graphs and their specific use cases.

Why Choose a Graph?

Graphs are ideal when you have two variables that can be plotted on separate axes. They are excellent for tracking correlation, especially when you expect a change in one variable to drive change in another.

Graph Example List

X-Y Scatter Graph With Lines
This common graph features both an X-axis and a Y-axis with numerical data scattered across the graph. The data points are connected by lines, demonstrating the correlation between two variables.

X-Y Scatter Graph Without Lines
This graph features multiple data points without connecting lines, focusing on how data points cluster in specific areas.

How to Use a Graph

Imagine being a project manager tasked with illustrating how increased advertising spending impacts annual sales. A scatter graph is the perfect choice for this situation.

To create a graph in PowerPoint, return to the Insert tab, choose the X Y (Scatter) section, and select your graph style. Then, enter your numerical data into the embedded Excel window.

As you enter data, Excel automatically updates the graph, visually demonstrating the trend and correlation between the variables.

Conclusion: What Is the Difference Between a Chart and a Graph?

Now you know the differences between charts and graphs! The choice of using one over the other depends on the data you wish to present and the story you want to share. Charts and graphs are always an upgrade over text-heavy slides, so look for opportunities to incorporate these data visuals into your presentations.
