# Gantt chart using pgfgantt with years divided into quarters?

I'm preparing a Gantt chart for a two year project; at this stage the timeline is pretty rough, and I'd like to set up the chart with three rows at the top: the title, the years, and then the quarters in each year. I don't want individual months anywhere.

I could of course do this directly with TiKZ and not bother with pgfgantt, but on the other hand it would be very nice to be able to use the nice functions which pgfgantt provides.

Is there an easy way to do this?

This is an attempt, hoping it will serve as a starting point. For more detail, please refer to its manual PgfGantt. inline=false means to write the label on the left edge.
