"""
Annual System Dispatch Stack
----------------------------

A stacked area plot of system-wide generation by technology over the
fixture's full horizon, with the load curve overlaid.

This is the most common at-a-glance view of a production cost simulation.
Generation is grouped by display technology (Coal, Gas-CC, Gas-CT, PV,
Wind, etc.) and stacked from the bottom up; the line on top is the load.
