Introduction

A Scatter Graph is a visualization that displays relationships between vital data points.  This visualization has several dots that are essential in showing the correlation between the variables you plot.

This chart best suits the job if your objective is to reveal hidden insights between two variables. Let’s use the example below. We want to see if there is a correlation between height and age in both genders.

Gender	Name	Age (Years)	Height (inches)	Weight (lb)
Male	Martin	8	50	52
Male	Martin	11	62	73
Male	Martin	16	66	134
Male	Martin	20	71	155
Male	Kim	6	48	52
Male	Kim	13	63	76
Male	Kim	17	68	131
Male	Kim	19	73	153
Female	Jada	9	52	57
Female	Jada	14	57	79
Female	Jada	16	62	117
Female	Jada	20	66	126
Female	Aubree	8	54	56
Female	Aubree	11	61	81
Female	Aubree	15	62	115
Female	Aubree	20	63	127

When you visualize the above data using it, it will appear as shown below.

Some of the insights you can identify from your graph include the following:

• The height of both genders increases with age.
• The dot sizes increase with time, which reveals the weight of both genders.

Understanding Line Graph

A Line Graph is also known as a Line Chart. A Line Graph is a visualization that shows how a variable changes over time.

You can also use the Line Graph to display how several variables change over time. One of the significant benefits of using a Line Graph is that it is simple to read and interpret.

You can use a Line Graph to display categorical and continuous data.

Let’s use an example of data you can use as a Line graph. The table below shows the age and height of several female respondents.

Age (Years)	Height (inches)
8	50
11	57
14	63
18	64

The Line Graph of the above data will appear as shown below.

One of the insights you can retrieve from the Line Graph is:

The height of the female respondents increases with age. In essence, the older respondents are taller than the younger ones.

Let’s now identify the differences between the two graphs.

Key Differences

Here are the differences between these two charts:

The image below shows a clear difference between the two graphs.

Graph A is a Line Graph. Graph B is the other one.

As you can see, one uses a line of best fit to display a relationship between two varying data sets, while the other relies on dots to show correlations and associations in your raw data.

On the other hand, a Line Graph connects various data points using straight line segments, unlike a Dot plot chart, which displays individual data points as dots. There is no line of best fit in a Line Graph; the straight-line segments help you identify trends and patterns in your data.

Real-Life Use Cases

Generally, it is better to use a Line Graph if your raw data includes non-numeric values. If your raw data only has numeric values, use the other chart.

You can use a simple Line Graph or a Line graph with multiple lines if you want to label your horizontal axis with text labels. These labels can represent evenly spaced values such as days, weeks, or years.

If you’re working with data in a table format, you can create a graph from the table to visualize the information. Additionally, you can use a Correlation Chart to modify the horizontal axis scale.

Let’s take a look at each in detail.

When to Use a Scatter Graph in Google Sheets?

• When you want to compare many data points without regard to time, this only means the more data you include in your Point Chart, the better the comparisons you can make with this visualization.
• An XY Plot uses values in its horizontal axis when you want to use a logarithmic scale on the horizontal axis. You have the freedom to customize it to become a logarithmic axis.
• When you want to display data that has grouped values, you can adjust your independent scales so that they show more information about the grouped sets of values.
• Use a Point Plot when you randomly distribute data on the x-axis.
• For instance, when you want to show patterns in your large data sets, it can also show linear and nonlinear trends and outliers.

When to Use a Line Graph in Google Sheets?

• When you want to track long-term and short-term changes, and your data has minor changes, a Line Graph will easily visualize such data.
• When you want to make comparisons, this is only applicable when using multiple lines in one graph to compare various variables over time.
• When you have continuous data, it includes age, height, length, and temperature. For example, the weight of a child will change with time.

Feature Comparison

Feature	Line Graph	Scatter Graph
Purpose	A Line Graph in Google Sheets displays meaningful insights into continuous data over time. The graph uses line segments to connect key data points relative to a specified time. A Line Graph is ideal for showing growth rates or trends at even intervals.	A Scatter chart in Google Sheets is best for displaying relationships between varying variables. It’s suitable for displaying associations and correlations. Still, you can use a Point Chart in cause-and-effect analysis for in-depth insights.
Axis	The x-axis shows dimensional variables, such as months and years. The y-axis displays key metrics in your data.	Both x and y axes depict varying metrics, which are, in most cases, numerical.
Plots	Line segments join key data points.	You draw a line of best fit in areas where the dots are mostly concentrated.
Amount of Data	One of the disadvantages of the Line Chart is the fact that it cannot handle bulky and complex data.	Point Plots are suitable for visualizing bulky and complex data sets.

FAQs

Should I use a scatter plot or line graph?

• Choose a scatter chart if you’re analyzing how two variables relate or if your data points are independent.
• Opt for a line graph when your data is sequential, such as time-based entries, and you aim to emphasize patterns or trends throughout the timeline.
