Localization of d3.js (d3.locale example of usage)
提问by Sergey Scopin
I'm trying to use d3.locale()in my app to display Russian names of months.
http://jsfiddle.net/j2feJ/2/Also, I need shortMonthsvariable to be in English, because they are in English in my database.
我试图d3.locale()在我的应用程序中使用来显示月份的俄语名称。
http://jsfiddle.net/j2feJ/2/另外，我需要shortMonths变量是英文的，因为它们在我的数据库中是英文的。
var ru_RU = {
"decimal": ",",
"thousands": "\xa0",
"grouping": [3],
"currency": ["", " руб."],
"dateTime": "%A, %e %B %Y г. %X",
"date": "%d.%m.%Y",
"time": "%H:%M:%S",
"periods": ["AM", "PM"],
"days": ["воскресенье", "понедельник", "вторник", "среда", "четверг", "пятница", "суббота"],
"shortDays": ["вс", "пн", "вт", "ср", "чт", "пт", "сб"],
"months": ["Январь", "Февраль", "Март", "Апрель", "Май", "Июнь", "Июль", "Август", "Сентябрь", "Октябрь", "Ноябрь", "Декабрь"],
"shortMonths": ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]
}
But display is still in English. Am I using it wrong?
但是显示还是英文。我用错了吗？

Calling d3.locale()doesn't change the internal workings of d3, it just creates and returns a localization object. You need to capture this return value and store it in a variable so you can use it later. Given the object you created in your example code, you could do that like this:
调用d3.locale()不会改变 d3 的内部工作方式，它只是创建并返回一个本地化对象。您需要捕获此返回值并将其存储在变量中，以便稍后使用。鉴于您在示例代码中创建的对象，您可以这样做：
var RU = d3.locale(ru_RU);
Then when you need a value to be localized, you must call for it explicitly. In your case, you want the full month names to be displayed as x-axis labels.
然后，当您需要本地化一个值时，您必须显式调用它。在您的情况下，您希望完整的月份名称显示为 x 轴标签。
To do this, you can add a .tickFormat()to your x-axis, and specify that the format should be your localized version of a full month name.
为此，您可以.tickFormat()向 x 轴添加，并指定格式应为完整月份名称的本地化版本。
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom")
.ticks(5)
.tickPadding(8)
.tickFormat(RU.timeFormat("%B"));
locale.timeFormat()is equivalent to d3.time.format(), except that it uses the locale that you created instead of defaulting to en_US. In this case localeis the variable RUwhich we created earlier.
locale.timeFormat()等价于d3.time.format()，不同之处在于它使用您创建的语言环境而不是默认为 en_US。在这种情况下locale是RU我们之前创建的变量。
Here is the updated JSFiddle.
这是更新的JSFiddle。
Remember, each time you want a localized string or value, you need to call for it explicitly. Use locale.numberFormat()in place of d3.format(), and locale.timeFormat()in place of d3.time.format(), where localeis a localization object created with d3.locale(). Hope that helps.
请记住，每次您想要一个本地化的字符串或值时，您都需要明确地调用它。使用locale.numberFormat()代替d3.format()和locale.timeFormat()代替d3.time.format()， wherelocale是用d3.locale().创建的本地化对象。希望有帮助。
