json - Getting subdocument by ObjectID directly in mongodb -


having structure: 

/* 0 */ {     "_id" : objectid("53f1f19a477aa5da607b20a4"),     "name" : "anna" }  /* 1 */ {     "_id" : objectid("53f1f192477aa5da607b20a3"),     "name" : "josh",     "mother" : objectid("53f1f19a477aa5da607b20a4") }

is possible complete document of mother instead objectid. mean, if query: db.tree.find({"name" : "josh"}) document of josh, not able name of anna because should query. it's possible in mongodb complete tree/json of documents when 1 of field refering document avoid multiple queries?

for clarity: mongodb not joins - resolving mother objectid document requires second query. antoniootero pointed out, drivers , orms, mongotemplate or mongoose, reference resolution you, automatically or request. should aware results in multiple database queries, however.

javascript - Highcharts multi-color line -

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 .
