This article describes how to go from a Principal Component Analysis created in Displayr:

To a scree plot based on the Principal Component Analysis:

## Requirements

- A Principal Component Analysis output created in Displayr. This does not need to be created with Dimension Reduction - Principal Components Analysis (you can make your own factor analysis or PCA), but the item does need to have an attribute called
.`values`

## Method

1. From the toolbar menu, select **Anything > Advanced Analysis > Dimension Reduction > Diagnostic > Scree Plot**.

2. From the object inspector on the right, select your Principal Component Analysis from the **Principal components analysis **drop-down box.

3. Click the **Calculate** button.
