javascript - Datamaps are showing small size map of India -


hi trying create map datamap , d3 js. showing map in reverse , small in size. how can resolve this. sharing js fiddle same.

    <script src="//cdnjs.cloudflare.com/ajax/libs/d3/3.5.3/d3.min.js"></script>     <script src="//cdnjs.cloudflare.com/ajax/libs/topojson/1.6.9/topojson.min.js"></script>     <script src="https://raw.githubusercontent.com/markmarkoh/datamaps/master/dist/datamaps.ind.js"></script>     <div id="container" style="position: relative; width: 500px; height: 300px;"></div>  var map = new datamap({   element: document.getelementbyid('container'),   scope: 'ind' });

https://jsfiddle.net/bxp9e9j1/

you need tell center , projection. add code:

  setprojection: function(element) {     var projection = d3.geo.equirectangular()       .center([80, 25])       .scale(600)       .translate([element.offsetwidth / 2, element.offsetheight / 2]);     var path = d3.geo.path()       .projection(projection);     return {path: path, projection: projection};   }

center of india: 20.5937° n, 78.9629° e

complete code:

var map = new datamap({   element: document.getelementbyid('container'),   scope: 'ind',   setprojection: function(element) {     var projection = d3.geo.equirectangular()       .center([80, 25])       .scale(600)       .translate([element.offsetwidth / 2, element.offsetheight / 2]);     var path = d3.geo.path()       .projection(projection);      return {path: path, projection: projection};   } });

tip: can change projection type to: mercator

projection: 'mercator',

that give flat map intead of rounded globe type.

hope help

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

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
