请原谅标题用词奇怪，我不太确定该如何提出问题，因此希望我在下面的说明会有所帮助。
我们的团队需要使用angularjs开发水平时间线，该时间线还可以正确缩放时间。我们在Codepen上遇到的许多时间表中，每个事件的间隔都是相等的。我们需要建立一个时间表来相应地调整事件日期。我们遇到的最接近的时间表是Codyhouse，但是我们不能使用jquery。
//Sample dates
var dates = ["6/12/2015", "8/15/2015", "10/22/2015", "11/2/2015", "12/22/2015"];
//For the purpose of stringifying MM/DD/YYYY date format
var monthSpan = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
//Format MM/DD/YYYY into string
function dateSpan(date) {
var month = date.split('/')[0];
month = monthSpan[month - 1];
var day = date.split('/')[1];
if (day.charAt(0) == '0') {
day = day.charAt(1);
}
var year = date.split('/')[2];
//Spit it out!
return month + " " + day + ", " + year;
}
//Main function. Draw your circles.
function makeCircles() {
//Forget the timeline if there's only one date. Who needs it!?
if (dates.length < 2) {
$("#line").hide();
$("#span").show().text(dateSpan(dates[0]));
//This is what you really want.
} else if (dates.length >= 2) {
//Set day, month and year variables for the math
var first = dates[0];
var last = dates[dates.length - 1];
var firstMonth = parseInt(first.split('/')[0]);
var firstDay = parseInt(first.split('/')[1]);
var lastMonth = parseInt(last.split('/')[0]);
var lastDay = parseInt(last.split('/')[1]);
//Integer representation of the last day. The first day is represnted as 0
var lastInt = ((lastMonth - firstMonth) * 30) + (lastDay - firstDay);
//Draw first date circle
$("#line").append('<div class="circle" id="circle0" style="left: ' + 0 + '%;"><div class="popupSpan">' + dateSpan(dates[0]) + '</div></div>');
$("#mainCont").append('<span id="span0" class="center">' + dateSpan(dates[0]) + '</span>');
//Loop through middle dates
for (i = 1; i < dates.length - 1; i++) {
var thisMonth = parseInt(dates[i].split('/')[0]);
var thisDay = parseInt(dates[i].split('/')[1]);
//Integer representation of the date
var thisInt = ((thisMonth - firstMonth) * 30) + (thisDay - firstDay);
//Integer relative to the first and last dates
var relativeInt = thisInt / lastInt;
//Draw the date circle
$("#line").append('<div class="circle" id="circle' + i + '" style="left: ' + relativeInt * 100 + '%;"><div class="popupSpan">' + dateSpan(dates[i]) + '</div></div>');
$("#mainCont").append('<span id="span' + i + '" class="right">' + dateSpan(dates[i]) + '</span>');
}
//Draw the last date circle
$("#line").append('<div class="circle" id="circle' + i + '" style="left: ' + 99 + '%;"><div class="popupSpan">' + dateSpan(dates[dates.length - 1]) + '</div></div>');
$("#mainCont").append('<span id="span' + i + '" class="right">' + dateSpan(dates[i]) + '</span>');
}
$(".circle:first").addClass("active");
}
makeCircles();
$(".circle").mouseenter(function() {
$(this).addClass("hover");
});
$(".circle").mouseleave(function() {
$(this).removeClass("hover");

$(".circle").click(function() {
var spanNum = $(this).attr("id");
selectDate(spanNum);

是否有一个现有的库在angularjs中执行此操作？如果没有，关于如何实现此目标的任何建议？例如，我们如何重构诸如this之类的时间轴，以考虑时间和日期？
