MongoDB count aggregate per month -


is there way total number of documents in mongodb database months (for example, can display chart showing evolution of number of users) in single request? or should request each month individually?

i don't want see number of users created in month total (this month + previous months).

each document in collection has field representing date created. total number of documents in mongodb database months, use range query query documents value created_on greater date representing start of month, , less date representing end.

assume start date 'start' , end date 'end'. query be,

db.users.count({created_on: {$gte: start, $lt: end}});

here nice explanation relevant topic. http://cookbook.mongodb.org/patterns/date_range/

refer answers in thread also. find objects between 2 dates mongodb

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
