hi highcharts community !

in angular 4 project, trying disable days , months in tooltip of horizontal bar chart, make appear hour minutes , secondes, if know how make it?

i tried property datetimelabelformats without success

thanks in advance

horizontalbar.ts:

constructor(public userservice3: userservice3) {    const timezoneoffset = new date().gettimezoneoffset();    const highcharts = require('highcharts');      highcharts.setoptions({   global: {    timezoneoffset: timezoneoffset   },       });          this.options = {         title : { text : '' },         chart: {  type: 'area',                     label: {                       format: '{data: %b}'                     }},         legend: { enabled: false },         credits: { enabled: false },         xaxis: { type: 'datetime',                 //  day: '%h',                 startontick: false,                 endontick: false,                 mintickinterval: 24 * 3600 * 1000,                 tickinterval: 36e5 * 2, // 2 hours                 },         yaxis: { min: 0,           max: 100,            labels: {               enabled: true           },              title: {              text: null            },         },         plotoptions: {           series: {               color: '#648e59',               fillopacity: 0.8,               fillcolor: '#648e59',               pointinterval: 36e5 * 2 // 2 hours                   }         },         series: [{           name: 'taux de fonctionnement',           data: [],         }]        };    }   saveinstance(chartinstance) {     this.chart = chartinstance;     console.log(chartinstance); }    public ngoninit () {   this.datasubscription = this.userservice3.getdata().subscribe((data)   => {   this.options.series[0].data = data.data.operating_details;   console.log(data);    }); }    ngondestroy() {   if (this.datasubscription){  this.datasubscription.unsubscribe();  }    }      public hidedem2(): void {    this.hidemeup = !this.hidemeup;     this.hidemeup = !this.hidemeup;      this.hideitup = !this.hideitup;         if (this.hideitup) {           this.opened.emit(true);         } else {           this.closed.emit(false);         }            console.log(this.hideitup);       }     }

horizontalbar.html:

      <chart [options]="options" (load)="saveinstance($event.context)">       <!--    <point (select)="onpointselect($event)"></point> -->       </chart>

if "tick in horizontal bar chart," mean axis labels, add following xaxis options:

labels: {     formatter: function () {         return highcharts.dateformat('%h:%m:%s', this.value);     }, },

that should return hours, minutes, , seconds of axis labels in format h:m:s.

more information highcharts.dateformat() can found here: http://api.highcharts.com/highcharts/highcharts.numberformat.

the highcharts.dateformat() function uses php's strftime formatting rules (see http://php.net/manual/en/function.strftime.php).

i hope information helpful you.

update: per emile's comments, tick in question chart's tooltip. in case, need modify follows:

tooltip: {     formatter: function () {         return highcharts.dateformat('%h:%m:%s', this.x);     }, },

see following resources highcharts documentation:

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
