# How to Plot a Log-Normal Distribution in Excel

This step-by-step tutorial explains how to plot the following log-normal distribution in Excel:

### Step 1: Define the X Values

First, let’s define a range of x-values to use for our plot.

### Step 2: Calculate the Y Values

The y values on the plot will represent the PDF values associated with the log-normal distribution.

We can type the following formula into cell B2 to calculate the PDF value of the log-normal distribution associated with an x value of 0.01, a mean value of 1, and a standard deviation of 1:

```=LOGNORM.DIST(A2, \$E\$1, \$E\$2, FALSE)
```

We can then copy and paste this formula down to every remaining cell in column B:

### Step 3: Plot the Log-Normal Distribution

Next, highlight the cell range A2:B22, then click the Insert tab along the top ribbon, then click the Scatter option within the Charts group and click Scatter with Smooth Lines:

The following chart will be created:

The x-axis shows the values of a random variable that follows a log-normal distribution with a mean value of 1 and a standard deviation of 1 and the y-axis shows the corresponding PDF values of the log-normal distribution.

Note that if you change the values for the mean or standard deviation in cells E1 and E2, respectively, the plot will automatically update.

### Step 4: Modify the Appearance of the Plot

Feel free to add a title, axis labels, and remove the gridlines to make the plot more aesthetically pleasing:
