You see below the main graph there is a zoomable smaller graph, showing market volume in this case. Well i cannot seem to find a way to display this data as bars. In the google code playground, when selecting an annotated time line the 'bottom graph' appears to only be available as a line chart, as opposed to the google finance bar chart.
any ideas how to overwrite this behaviour?
