# Annotate Data Point

:lock: ChartDataPoint.**Annotate**

## Overview

This operation is used to Annotate a Chart Data Point.

## Setup

No specific setup is required other than to meet the preconditions of the transaction.

## Preconditions

1. The **Chart** exists in the system and it is Active.
2. The **Chart** Data Point exists in the system and it is Active (Universal State).

## Sequence of Steps

### Step 1

1. In the Logical Chart, select the Chart Data Point you want to annotate.
2. Select Annotate to open the Annotate Chart Data Point wizard.
3. Verify the **Chart** Data Point information.
4. Depending on the value of the Data Point, you can enter a code for the annotation. This will depend on whether the Data Point value is between the set limits for the chart or if there is a violation of those limits, as well as a specific configuration of the parent **Chart** entity:
   * For non-violations, if the General Annotation Code Source property of the **Chart** is set to a specific Lookup Table, you can select a value from that Lookup Table.
   * For violations, if the Violation Annotation Code Source property of the **Chart** is set to a specific Lookup Table, you can select a value from that Lookup Table.

5. Enter or edit the annotation in the textbox.
6. Optionally, enter a comment.
7. Select **Annotate** to complete the operation.
