Tooltips on column headings - agileChilli
Using column headings for an overview of the data
For numeric fields, when you hover over a field name in pane 2, a tooltip appears calculating the sum and average for the column. This works when filtering as well – you’ll get just the figures for the filtered data.
For lookup and some other text fields, agileBase lists all values in the report and shows how many times each appears with a little graphic – useful for a quick overview.
