javascript - highchart - irregular time series -


i trying plot irregular time series data onto high chart such example http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/spline-irregular-time/. 

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", brand: "chrysler", count: 3}, {errordate: "2017-09-06", brand: "chrysler", count: 6}, {errordate: "2017-09-07", brand: "chrysler", count: 1} ];

i have data in variable dataarray, , i've attempted build out series data based on each brand data coming in, challenge having need dynamically pass in 'errordate' along each data point in series plotted appropriately.

what best way accomplish this?

fiddle: https://jsfiddle.net/ntt5oc21/

you should prepare data before passing highcharts. doc page should helpful: https://www.highcharts.com/docs/chart-concepts/series

here processed data:

var seriesarr = []; dataarray.foreach(function(point) {    var newpoint = [point.errordate, point.count],     seriesindex = seriesarr.findindex((series) => series.name === point.brand);    if (seriesindex === -1) {     seriesarr.push({       name: point.brand,       data: [newpoint]     });    } else {     seriesarr[seriesindex].data.push(newpoint);   } });

then can use 1 of methods methods , properties dynamically modifying chart api section: http://api.highcharts.com/highcharts

for example: 

seriesarr.foreach(function(series) {     chart.addseries(series); });

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
