# Residuals and slopes

When you have added a regression line to a graph, you can also:

- Visualize the residuals from the regression analysis
- Visualize the slopes of the equation at each point
- Generate additional data columns from the residual and slope values

Licensed featureResidual and slope calculations require an [active trial](/v1/docs/accounts-trials-and-licensing) or a purchased license.

This page will focus on the residuals. See [this other article about working with slopes (differentials)](/v1/docs/slope-of-the-line-differential).

To add these additional features to a regression graph, open the advanced features here:

Then you can select to add **Residuals** and/or **Slopes** to the graph. This example has residuals added:

Residuals are the differences between the values on the regression line, and the actual sample values.

Slopes are the slope of the equation line at that X value (i.e. the first differential of the equation).

Clicking the "Create new columns from these values" button allows you to generate a new column in your dataset, with the slope and/or residual values, so these can be inspected and plotted.
