python - Highcharts stacked percentage area -


i have different series of data actual , expected value. each country it's expected there's done @ least xx assignments depending on team size. expected value can increase or decrease. new data retrieved every day , saved in sqlite database. idea present data using flask in python.

the sqlite database has following layout: data layout

i dreaming of plotting these data in such way it's shown in percentage wise. let's if see plot greece only, @ maximum expected value, in case 12, , plot 58% of area since maximum covered value 7. if see plot poland, expected value 22, means in order reach 100% both countries have complete assignments.

i have tried, kind of lost. here code: 

highcharts.chart('container', { chart: {     type: 'area' }, title: {     text: 'covered assignents country' }, xaxis: {     type: 'datetime',     tickmarkplacement: 'on',     title: {         enabled: false     } }, yaxis: {     title: {         text: 'percent'     } }, tooltip: {     pointformat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.percentage:.1f}%</b> ({point.y:,.0f} assignments)<br/>',     split: true }, plotoptions: {     area: {         stacking: 'percent',         linecolor: '#ffffff',         linewidth: 1,         marker: {             linewidth: 1,             linecolor: '#ffffff'         }     } }, series: [{     name: 'greece',     data: [{x: date.utc(2017,09,08), y:4}, {x: date.utc(2017,09,09), y:6}, {x: date.utc(2017,09,10), y:7}] }, {     name: 'poland',     data: [{x: date.utc(2017,09,08), y:1}, {x: date.utc(2017,09,09), y:3}, {x: date.utc(2017,09,10), y:5}] }, {     name: 'italy',     data: [{x: date.utc(2017,09,08), y:1}, {x: date.utc(2017,09,09), y:2}, {x: date.utc(2017,09,10), y:7}] }] });

i hope makes sense :)

change stacking "percent" "normal" ("percent" fills chart top). need calculate y values percentages before make data series:

data: [{x: date.utc(2017,09,08), origtasks:4, y:14}, ...

above, 14 percentage somehow calculate yourself. note can include other data in series well, , later access in tooltips example (here: origtasks).

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
