How to create a scatter plot in Excel

So, you enter two sets of numeric data into two separate columns. For ease of use, the independent variable should be in the left column as this column is going to be plotted on the x axis. The dependent variable the one affected by the independent variable should be in the right column, and it will be plotted on the y axis.

Exploring charts in Excel and finding that the one you pick isn’t working well for your data is a thing of the past! Try the Recommended Charts command on the Insert tab to quickly create a chart that’s just right for your data. Click Recommended Charts and select the chart. Making an xy scatter plot. 1. How to make a scatter plot in Excel; 2. Open a new workbook and enter your data; 3. Select “Insert” and.

In our example, we are going to visualize the relationship between the advertising budget for a certain month independent variable and the number of items sold dependent variable , so we arrange the data accordingly: With the source data correctly organized, making a scatter plot in Excel takes these two quick steps:. The scatter diagram will be immediately inserted in your worksheet: Basically, you may consider the work done.

Or, you can customize some elements of your graph to make it look more beautiful and to convey the correlation between the two variables clearer. Scatter with lines is best to be used when you have few data points.

Overall, there exist three types of correlation:. Positive Correlation - as the x variable increases, so does the y variable. An example of a strong positive correlation is the amount of time the students spend studying and their grades. Negative Correlation - as the x variable increase, the y variable decreases. Ditching classes and grades are negatively correlated - as the number of absences increases, the exam scores decrease.

No Correlation - there is no evident relationship between the two variables; the dots are scattered around the entire chart area. For example, students' height and grades appear to have no correlation as the former does not affect the latter in any way.

To fix this, click on the labels, and then click on the overlapping one so that only that label gets selected. Point your mouse cursor to the selected label until the cursor changes to the four-sided arrow, and then drag the label to the desired position.

As the result, you will have a nice Excel scatter plot with perfectly legible labels: Add a trendline and equation To better visualize the relationship between the two variables, you can draw a trendline in your Excel scatter graph, also called a line of best fit. To have it done, right click on any data point and choose Add Trendline… from the context menu. Excel will draw a line as close as possible to all data points so that there are as many points above the line as below.

Additionally, you can show the equation for the trendline that mathematically describes the relationship between the two variables. For this, check the Display Equation on Chart box on the Format Trendline pane that should appear in the right part of your Excel window immediately after you've added a trendline. The result of these manipulations will look similar to this:. What you see in the screenshot above is often called the linear regression graph , and you can find the detailed guidelines on how to create it here: How to make a linear regression graph in Excel.

As already mentioned, a scatter plot usually displays the independent variable on the horizonal axis and the dependent variable on the vertical axis. If your graph is plotted differently, the easiest fix is to swap the source columns in your worksheet, and then draw the chart anew. If for some reason rearranging the columns is not possible, you can switch the X and Y data series directly on a chart.
