# S-curve
An **s-curve** is a type of line chart which shows progress over time.
In this example below, the work completed (a numeric field) is plotted against time. The work completed is cumulative to show the progress over time.
The above chart is configured by simply selecting the numeric **work** field (e.g. work completed, effort, cost, or another such measure), against the date. In this case, the work field is named 'Weighting':\
To convert the data to cumulative, enable that option under Data Manipulation:\
Often, it is desirable to display a second line which is the **target**. This allows comparison of the ideal progress against expected or target progress.
To add this second line, click **Next** at the bottom of the configuration:
Enter the same List URL, select the same numeric data field (weighting), but this time, select your **target date** field.\

If you're using s-curves, this ties in perfectly with our gantt scheduling tool **baselines** functionality. [See more info](https://365automate.gitbook.io/365automate-gantt/baselines).
