Gantt-type feature needed

Hello - I’m looking for a Gantt-chart type feature but this is not for a project management-type with a task and days to complete, but for a display of advertising media.

At it’s most basic level this would be line items of media (such as Website X, TV Station Y etc) with a start and end date, and that would display a bar between the two dates.

Ideally, this would be customizable to be grouped by channel. And the ability to stretch or compress the time along the X axis.

Are there any native solutions for this, or plugins? Most of the plugins I have seen are tailored to displaying “tasks”.

Thanks in advance!

have you found a solution for this?
