在軸上設置最小值和最大值

我正在使用anuglar-nvd3，並且找不到API上的任何文檔。我現在面臨的問題是如何在xAxis和yAxis上設置最大值&最小值。在軸上設置最小值和最大值

換句話說，無論數據，軸將有一個最低的-1和1最大

代碼：

var app = angular.module('plunker', ['nvd3']); 

app.controller('MainCtrl', function($scope) { 
$scope.options = {

       }, 
       showDistX: true, 
       showDistY: true, 
       tooltipContent: function(key) { 
        return '<h3>' + key + '</h3>';
