我有一个创建一个离散条形图的应用程序。由于我无法解释的某些原因(这似乎是库中的内部错误)，y轴缩放为一个数据值，该数据值不是数组中整数的最高值(在我的数组中，它会缩放)改为5674，而不是25797)。如何解决此错误？谢谢。
我的数据示例(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(app.html)的示例:
<!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="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<nvd3 options="barOptions" data="barData"></nvd3>
</body>
</html>
我的 Controller (app.js)的示例:
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;
}]);
最佳答案
*更新* (同时，我找到了解决方案。我必须回答自己的问题。)
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]
