# Baselines A baseline is a great way to visualise the progression of a project compared to the original planned schedule. This involves taking a "snapshot" of your tasks which will then be displayed in small, gray colored task bars:

The baseline data is recorded in two additional Date fields in your SharePoint List. To configure baselines, edit your webpart and select the Baselines section:

The **Baseline Start Date** and **Baseline End Date** must be set to fields in your list before baselines can be used. The option "**Show baseline reset option for individual tasks**" enables a right-click menu option:

Clicking this will reset the task baseline to match the task:

The option "**Show baseline reset option for the entire chart**" enables a command bar button: {% hint style="info" %} Clicking this button will update the baseline for the entire chart. Using this option is usually done during the initial project planning phase, after which this button can be hidden. {% endhint %}

{% hint style="success" %} If you're using baselines, why not [add an s-curve using our ListBurst Charts product](https://docs.listburst.app/advanced-chart-types/s-curve)? {% endhint %}
