I have a issue on mongo db to getting records using group by '$group' in aggregate function on date as 'created' but we have datetime format in table mongoDb database.

when I run the mongo query I am getting error "can't convert from BSON type string to Date"



$date = date('Y-m-d',strtotime(-1 month));

$users = $this->common_model->aggregate($this->database['USER_DATA'], array(array('$match' => array('created' => array('$gte' => $date))),

        array('$sort' => array('_id.created' => -1)),

        array('$group' => array('_id' => array('year' => array('$year' => '$created'), 'month' => array('$month' => '$created'), 'day' => array('$dayOfMonth' => '$created')), 'count' => array('$sum' => 1))),

        ));


before we are using 



array('$group' => array('_id' => array('created' => '$created')), 'count' => array('$sum' => 1)),


Its was working but records not as required as per group by date, because in table we have datetime.

What visual should I use to simply compare current year value vs last year in Power BI desktop

Image
0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
