# Gantt: Connectors

### What Are Connectors in Gantt Charts?

{% hint style="success" %}

### Connectors in Gantt charts visually represent dependencies between tasks.

In enterprise planning scenarios, projects will have multiple inter-dependencies. Connector lines show how tasks are linked, the sequence of work, and how delays in one task can impact the overall project timeline.

### Setup guide for connectors in Gantt charts

The **Connect to**, **Connector type**, and **Connector ID** data wells can be used to configure connectors in your Gantt charts. These fields have been highlighted in the sample dataset shown in the image.

#### **1. Connect to**

This field is mandatory to plot connector lines. It identifies the predecessor task for the current task, i.e., the task that the current task depends on.

#### **2. Connector type:**&#x20;

Determine how the start or completion of one task affects another. In the images below, notice how the connector lines are plotted at the beginning or end of the progress bar based on the connector type.

<table><thead><tr><th width="246">Connector Type</th><th>Description</th></tr></thead><tbody><tr><td>FinishStart (FS)</td><td>The task can begin only after the predecessor task is completed.</td></tr><tr><td>StartStart (SS)</td><td>The task can start only after the predecessor task has started.

#### **3. Connector ID**

Uniquely identifies each dependency. In this example, we have 'UI/UX' subtasks under the 'Design' and 'Requirements' tasks - adding a connector ID ensures that the dependency is plotted correctly. Notice how the *Task ID* is used in the **Connect To** field instead of the subtask name.

Map the Connector ID field to ensure dependencies are plotted accurately even if the task/subtask descriptions change in the source.
