Chart Type - Histogram
Histograms are useful for showing the distribution of a data set while aggregating up to see more general trends. Here is the SQL code (in a handy parameterized snippet!) for binning numeric data and creating histograms from columns.
Snippet Name: histogram(table_name,column,bin_size)
select [column] - mod([column], [bin_size]) as value , [column] - mod([column], [bin_size]) || ' - ' || [column] + ([bin_size] - mod([column], [bin_size])) as label , count(1) from [table_name] group by 1 , 2 order by 1 asc
Alternatively, you can create custom bin sizes that vary in width using a case when statement
select case when [column] < 100 then '100' when [column] < 500 then '500' when [column] < 1000 then '1000' else '> 1000' end as [column] , count(1) from [table_name] group by 1
