Strip Lines

This demo illustrates how to use strip lines to highlight different times in the DevExtreme JavaScript Gantt component. The Gantt stores strip lines in its stripLines collection. You can specify a title (title) and appearance settings (CssClass) for each strip line.

Use the start property to specify an individual strip line or combine it with the end property to specify a time interval.
