【中文标题】Angular-nvD3 条形图 y 轴缩放错误 (AngularJS)【英文标题】:Angular-nvD3 Bar Chart y-axis Scaling Bug (AngularJS) 【发布时间】:2016-08-13 14:52:50 【问题描述】:我有一个创建一个离散条形图的应用程序。由于某种我无法解释的原因(这似乎是库中的内部错误),y 轴缩放到一个数据值,该值不是数组中整数的最高值(在我的数组中,它缩放到 5674 而不是 25797)。我该如何修复这个错误?谢谢。
我的数据样本(fetched-data.json):
["0":"1","1":"323","ID":"1","STOCK":"323","0":"2","1":"1401","ID":"2","STOCK":"1401","0":"3","1":"5674","ID":"3","STOCK":"5674","0":"4","1":"25797","ID":"4","STOCK":"25797"]
HTML 示例 (app.html):
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<meta charset="utf-8" />
<title>Angular-nvD3 Bar Chart</title>
<script data-require="lodash.js@4.6.1" data-semver="4.6.1" src="https://cdn.jsdelivr.net/lodash/4.6.1/lodash.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.6/d3.min.js" charset="utf-8"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-nvd3/1.0.5/angular-nvd3.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<nvd3 options="barOptions" data="barData"></nvd3>
</body>
</html>
我的控制器示例 (app.js):
var app = angular.module('myApp', ['nvd3']);
app.controller('MainCtrl', ['$scope', 'services', function($scope, services)
$scope.barData = [];
var stock =
key: 'Product stock',
values: []
;
stock.values = _.map(data.data, function(prod)
return
label: prod.ID,
value: prod.STOCK
;
);
console.log(stock);
$scope.barData.push(stock);
);
$scope.barOptions =
chart:
type: 'discreteBarChart',
height: 450,
margin :
top: 20,
right: 20,
bottom: 50,
left: 55
,
x: function(d)return d.label;,
y: function(d)return d.value;,
showValues: true,
valueFormat: function(d)
return d3.format(',.4f')(d);
,
duration: 500,
xAxis:
axisLabel: 'X Axis'
,
yAxis:
axisLabel: 'Y Axis',
axisLabelDistance: -10
;
])
.factory('services', ['$http', function($http)
var serviceBase = 'services/'
var object = ;
object.getData = function()
return $http.get('fetched-data.json');
;
return object;
]);
【问题讨论】:
【参考方案1】:* UPDATE * (同时,我找到了解决方案。我必须回答我自己的问题。)
只需通过向图表选项添加以下选项来强制 Y 最大值:
yDomain: [0, 25797]
我在这里找到了这个“错误”的解决方案:https://github.com/krispo/angular-nvd3/issues/47
