You can add flags to show min max values. I am using flags with highstock js. On load event I am finding min and max values and add series of type flags. 

this.addSeries({
            type: 'flags',
            data: [{
              x: newArr[maxIndex].x,
              y: newArr[maxIndex].y,
              title: 'Max:'+newArr[maxIndex].y,
            },{
              x: newArr[minIndex].x,
              y: newArr[minIndex].y,
              title: 'Min: '+newArr[minIndex].y,
            }],

          });
