{             options: {                 chart: {                     type: 'line',                     margintop: 80,                     style: {                         fontfamily: 'serif',                         fontsize:14                     },                     events:{                         redraw:function(e){                             console.log(e)                             var elem=e.target.renderer.element()                             console.log(elem)                             console.log('i reloaded')                         }                     }                     //backgroundcolor:'rgba(255, 255, 255, 0.1)'                 },                 exporting: {                     enabled: false                 },                 plotoptions: {                     series: {                         animation: false,                         marker: {                             symbol: 'circle'                         },                         linewidth: 1,                         events: {                             afteranimate: function () {                                 console.log('lol')                             }                         }                     }                 },                 colors: ['#2c91de', '#165a8e'],             },             tooltip: {                 style: {                     padding: 10,                     fontweight: 'bold'                 }             },             title: {                 text: ""             },             loading: false,             series: [],             func: (chart) => {                 this.$timeout(() => {                     console.log(chart)                     var ren = chart.renderer;                     var group = ren.g().add();                     var attrforvline = {                         'stroke-width': 3,                         stroke: '#2c91de',                         dashstyle: 'solid'                     };                      (var = 0; < chart.series[0].data.length; i++) {                         var plot1 = chart.series[0].data[i];                         var plot2 = chart.series[1].data[i];                          /**                          * creating line segments across graphs.                          * keeping zindex low these lines.                          */                         ren.path([                             'm',                             plot1.plotx + chart.plotleft,                             plot1.ploty + chart.plottop,                             'v',                             plot2.ploty + chart.plottop                         ]).attr(attrforvline).add();                     }                 }, 1000);             },             yaxis: {                 tickinterval: 40,                 title: {                     text: ''                 }             },             xaxis: {                 startontick: true,                 endontick: true,                 linecolor: '#000000',                 type: 'datetime',                 labels: {                     rotation: -60,                     format: '{value:%m-%d-%y}',                     align: 'right'                 }             }         };

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
