About the Gantt chart maker
Dates that update themselves
Give a task an id and start the next one with after id. Change the first date or a duration and everything after it moves along.
Formats
dateFormat sets how you write dates (YYYY-MM-DD is safest). axisFormat sets how they appear on the chart, for example %d %b for 02 Nov.
Frequently asked questions

- Use milestone with a zero length: Go live :milestone, after t1, 0d.
- Is my plan uploaded?
- No. It is drawn in your browser.
