i have highchart potentially receives data duplicate keys, wondering how can build logic that'll merge 2 key/values 1 series. this data var dataarray = [{ errordate: "2017-09-07", brand: "toyota", count: 3 }, { errordate: "2017-09-02", brand: "ford", count: 258 }, { errordate: "2017-09-03", brand: "ford", count: 239 }, { errordate: "2017-09-04", brand: "ford", count: 197 }, { errordate: "2017-09-05", brand: "ford", count: 187 }, { errordate: "2017-09-06", brand: "ford", count: 418 }, { errordate: "2017-09-07", brand: "ford", count: 344 }, { errordate: "2017-09-03", brand: "mercedes", count: 43 }, { errordate: "2017-09-04", brand: "mercedes", count: 220 }, { errordate: "2017-09-03", brand: "chrysler", count: 3 }, { errordate: "2017-09-04"...

my purpose needs find out time gap between every row. should go 1 second 1 second, see until 11:40, there large one. example, time a3-a2=b1. solved problem already, code following. it runs ok, in end of column b, there long list of 00:00:00. want match last number of column b column a, means column b , should have same length. thousands of 00:00:00 in end. sub calculatetimegap() columns("b:b").insert shift:=xltoright, copyorigin:=xlformatfromleftorabove range("a1").value = "time" columns("a:a").numberformat = "hh:mm:ss" columns("b:b").formula = "=a2-a1" range("b1").value = "time difference(s)" columns("b:b").numberformat = "hh:mm:ss" lrow = cells(rows.count, 1).end(xlup).row end sub time time difference(s) 11:28:37 00:00:01 11:28:38 00:00:01 11:28:39 00:00:01 11:28:40 00:11:35 11:40:15 00:00:01 11:40:16 00:00:01 11:40:17 00:00:01 11:40:...

i need perform aggregation on incoming data based on spark driver timestamp, without watermark. data doesn't have timestamp field. the requirement is: compute average of data received every sec (it doesn't matter when have been send) for example need aggregation on data received every trigger, previous rdd streaming api. is there way ? you can create own sink , operation on each addbatch() call: class customsink extends sink { override def addbatch(batchid: long, data: dataframe): unit = { data.groupby().agg(sum("age") "sumage").foreach(v => println(s"result=$v")) } } class customsinkprovider extends streamsinkprovider datasourceregister { def createsink( sqlcontext: sqlcontext, parameters: map[string, string], partitioncolumns: seq[string], outputmode: outputmode): sink = { new personsink() } def shortname(): string = "person...

i direct user page hosted bokeh server along bit of metadata. example might want direct user to http://my-server/my-page?var=value i {'var': 'value'} request in bokeh server application code on python side can respond accordingly. is possible? if so, how? a bokeh core dev pointed me documentation page: https://bokeh.pydata.org/en/latest/docs/user_guide/server.html#accessing-the-http-request in particular, available on document object: # request.arguments dict maps argument names lists of strings, # e.g, query string ?n=10 result in {'n': [b'10']} args = curdoc().session_context.request.arguments try: n = int(args.get('n')[0]) except: n = 200
