Download shows a graph of the current global download speed.
The light green-colored line represents the global download rate limit. If no limit is set for the global download rate, this line will not be shown.
The solid green-colored line represents the current global download rate, counting only payload data (as opposed to including overhead).
The long-dashed green-colored line represents the global download rate for payload data downloaded from local peers.
The short-dashed green-colored line represents the global download rate, including download overhead. If gui.graph_overhead is disabled, this line will not be shown.
