Question 1

What is a scatter plot?

Accepted Answer

A scatter plot (also called a scatter graph or scatter diagram) displays individual data points plotted along two axes. Each point represents a pair of values, making scatter plots ideal for visualizing the relationship or correlation between two variables.

Question 2

When should I use a scatter plot?

Accepted Answer

Use a scatter plot when you want to explore relationships between two numerical variables — for example, height vs. weight, advertising spend vs. sales, or study hours vs. test scores. They're also useful for spotting outliers and clusters in your data.

Question 3

How do I enter data for the scatter plot?

Accepted Answer

Enter X values as a comma-separated list (e.g. 10,20,30,40) in the X values field, and corresponding Y values in the Y values field (e.g. 15,25,35,45). Each X-Y pair becomes one data point on the chart.

Question 4

Can I customize the appearance of the scatter plot?

Accepted Answer

Yes. You can set the chart title, axis titles, and use color pickers to customize the background color, title color, axis label color, axis text color, and the color of the data points and connecting line.

Question 5

What does the trend line in the scatter plot show?

Accepted Answer

The connecting line between points in our scatter plot shows the sequence of your data. To visually assess correlation, look at the overall direction of the points — upward trending points suggest a positive correlation, downward suggests negative, and random distribution suggests no correlation.
