Certain trial-file records (e.g. Ely Smith 1750 age 20 Robbery) return a count() of 2 rather than 1, and I can't figure out why. The count returned from the sql query seems to be used only in the json.php file to determine how big to make the brick for the specified crime/gender/agegroup etc for the specified year. So, I modified one line of code in the json file to replace the value of count() with 1.
The _execute function in the Search.php file has been simplified so that it always uses
Previously table output used that argument and chart output used the argument
$this->_select->group($this->allowedGroups[$this->_data['group']] . ', YEAR(tf.trial_file_start_date)');
but that caused inconsistencies in the total number of records returned, which I haven't been able to resolve.
The issue now is that the chart appears as a stack of same-coloured bricks for each year-attribute pair rather than 1 brick of height count(). For the time being I'll trade off the slightly less elegant display for the accurate and consistent counts.
