access data when ordering
configurable display changes on reset
don't draw axis off "screen" as it doesn't work in (at least) IE10+
provide calculated bar width after render
allow the brush to be under the chart
allow non-stacked line chart
move unstacked logic into stack
only provide full stack data if requested
composite chart needs overriden y axis min/max
distinguish between simple client data and internal or full client data
row chart uses different colours for each row unless they are stacked in which case the colours are per stack (as for the bar chart)
groups are more abstract so can't check for identity in this test
underlying data structure changed
default title uses key and value accessors (but only works for first stack)
structure of row data changed
