# How to Create an S Curve Excel: A Step-by-Step Guide

Creating an S curve in Excel is a way to visually represent growth over time. It’s often used in project management and business analysis to forecast performance. After reading this paragraph, you should have a basic understanding of how to create an S curve in Excel using data points, chart tools, and some nifty formatting tricks.

## Step by Step Tutorial to Create an S Curve in Excel

Creating an S curve in Excel might seem daunting, but it’s actually quite straightforward once you break it down. Let’s dive in!

### Step 1: Enter Your Data

Input your time points and corresponding data values into two columns in Excel.

In the first column, list the time intervals for your project or analysis. In the second column, enter the data points that correspond to each time interval. Make sure your data is in chronological order to create an accurate S curve.

### Step 2: Insert a Scatter Plot

Go to the ‘Insert’ tab and click on ‘Scatter’ to insert a scatter plot.

After you’ve entered your data, highlight it and then click on ‘Insert’ in Excel’s top menu. From there, choose the ‘Scatter’ chart option. This will create a basic scatter plot, which is the foundation of your S curve.

### Step 3: Add a Trendline

Right-click on a data point, select ‘Add Trendline,’ and choose the ‘Logarithmic’ option.

Once your scatter plot is in place, right-click on any of the data points in the graph. From the dropdown menu, select ‘Add Trendline.’ In the Trendline options, choose the ‘Logarithmic’ type to create the distinctive S shape.

### Step 4: Format the Trendline

Customize the trendline to extend and smooth out the curve.

After adding your logarithmic trendline, you can format it further to extend the line, so it covers the full range of your data and smooths out to create a more defined S shape. You can do this by right-clicking the trendline, selecting ‘Format Trendline,’ and adjusting the options as needed.

### Step 5: Finalize Your Chart

Adjust the chart title, axis labels, and other formatting options to finish your S curve.

Your S curve is almost complete! Now, it’s just a matter of adding finishing touches like a descriptive chart title, axis labels, and maybe some color to make it pop. Play around with Excel’s formatting tools to make your chart easy to read and visually appealing.

## What Happens After You Complete the Action

Once you’ve completed these steps, you’ll have a functional and visually appealing S curve that represents your data over time. You can use this curve to analyze growth trends, make forecasts, and present your findings in a clear and professional manner.
