How to display text in place of number in angularjs materials silder

enter image description here

What I want when you click on the slider, then on its tooltip it show text in place of the number.

Here is the code:

HTML:

<div ng-controller="AppCtrl" class="sliderdemoBasicUsage" ng-app="MyApp">
  <br>
  <br>
  <br>
  <br>
  <md-content style="margin: 16px; padding:16px">
    <br>
    <br>
   <md-slider flex class="md-primary" md-discrete ng-model="rating3" step="1" min="1" max="5" aria-label="rating">
      </md-slider>
  </md-content>
</div>

Angular Code:

angular.module('MyApp')

.controller('AppCtrl', function($scope) {
});

Angular Material does not support it.

for more detail check slider.js of angular-material module

function SliderDirective($$rAF, $window, $mdAria, $mdUtil, $mdConstant, $mdTheming, $mdGesture, $parse, $log) {
  return {
    scope: {},
    require: '?ngModel',
    template:
      '<div class="md-slider-wrapper">\
        <div class="md-track-container">\
          <div class="md-track"></div>\
          <div class="md-track md-track-fill"></div>\
          <div class="md-track-ticks"></div>\
        </div>\
        <div class="md-thumb-container">\
          <div class="md-thumb"></div>\
          <div class="md-focus-thumb"></div>\
          <div class="md-focus-ring"></div>\
          <div class="md-sign">\
            <span class="md-thumb-text"></span>\
          </div>\
          <div class="md-disabled-thumb"></div>\
        </div>\
      </div>',
    compile: compile
  };

inside this code

 <span class="md-thumb-text"></span>

is used to render the slider's range number. and following method is used to render it

function postLink(scope, element, attr, ngModelCtrl){
}

you can modify function's content like this

var _values = ["very low", "low", "average", "good", "best"];
thumbText.text( _values[ngModelCtrl.$viewValue] );

to render text rather integer value.

<p ng-bind="val" ng-init="val=20"></p>
            <div class="slider" ui-jq="slider"  ng-slider-model="val" ui-options="sliderOpt4"></div>
          </div>

Here is the an directive you can access and show the value of controller value ..with html and css

.directive('ngSliderModel', ['$parse', function($parse) {
   return {
     scope: {
       ngSliderModel: '=',
       uiOptions: '='
     },
     restrict: 'A',
     required: ['ngSliderModel'],
     link: function(scope, element, attrs) {
       // check there is uiOption or not 
       var options = ('uiOptions' in attrs) ? scope.uiOptions : {};
       // get the value of ngSlider Model 
       var val = scope.ngSliderModel;
       // if value is  range   [15,25]   then return values for uiOptions propertyName  else value for singles   
       var propName = (angular.isArray(val)) ? 'values' : 'value';
       /* if you  want to slide when the scope value changed not from slider... 
        watch the ngSliderModel attribute 
       */
       scope.$watch('ngSliderModel', function(newValue){

         element.slider(propName, newValue);
       });
       // set value for options 
       options[propName] = val;
       // binding slide event 
       element.bind('slide', function() {
         // Read the current value 
         var value = element.slider('option', propName);

         scope.$apply(function() {
           // Apply the value to scope 
           scope.ngSliderModel = value;
         });
       });
     }
   };
 }]);

Unfortunately that functionality is not supported as it's not technically part of the material spec for sliders.

For a likert scale you should consider the selection controls spec of material. Otherwise, you can get away with it in Angular Material by using a horizontal row of radio buttons.
