BaseLine

17 Feb 202211 minutes to read

The baseline feature enables users to view the deviation between the planned dates and actual dates of the tasks in a project. Baseline dates or planned dates of a task may or may not be same as the actual task dates. The baseline can be enabled by setting the RenderBaseline property to true and the baseline color can be changed using the BaselineColor property. To render the baseline, you should map the baseline start and end date values from the data source. This can be done using the BaselineStartDate and BaselineEndDate properties. The following code example shows how to enable a baseline in the Gantt control.

<ejs-gantt id='Gantt' dataSource="ViewBag.DataSource" height="450px" renderBaseline="true" projectStartDate="04/01/2019" projectEndDate="04/30/2019">
                    <e-gantt-taskfields id="TaskId" name="TaskName" startDate="StartDate" duration="Duration" child="SubTasks" progress="Progress"
                        endDate="EndDate" baselineEndDate="BaselineEndDate" baselineStartDate="BaselineStartDate">
                    </e-gantt-taskfields>
