Subject: Meter: allocate GraphData buffer dynamically

On wide screens the previous value of 256 could end up insufficient to
cover the screen space allocated to the graph, leaving it awkwardly
truncated mid-column.  We now allocate the buffer dynamically instead,
growing it to accommodate whatever width the graph occupies.
