Can weekends be excluded?

Add excludes weekends under dateFormat; tasks spanning a weekend are extended automatically and weekends are shaded on the axis.

Does the space before the colon matter?

No. Task name :a1, … and Task name:a1, … both work. After the colon come the status tags, the task id, the start (a date or after id) and the duration.

The chart is too long for the page

Export the PNG at 3x so it stays readable when scaled to page width in Word, or split it into one chart per month.

When to use it

Kick-off meetings, weekly status reports and the implementation plan in a proposal. Tasks are chained with after, so changing the first date shifts the whole chain; done and active mark finished and current tasks, and milestone marks the launch.

Making it yours

Change the start date only on the Discovery line; every task that uses after moves with it.
Durations are the 5d, 15d values; an end date can be used instead of a duration.
Delete the todayMarker off line to show a vertical line for today.
The axis labels follow axisFormat: %m-%d is month-day, %b shows the month name.
