数据展示时间线展示工具Timeline

每日一贴,今天的内容关键字为数据展示

    时光线展示工具Timeline[1],可以实现网页上展示一个时光轴。在时光相关的数据展示中,有比较好的效果。测试了下,详细的用法是这样的。

    

1.编写html页面,引入JS脚本,引入JSON数据,设定待表现日历位置

    <scriptsrc="http://static.simile.mit.edu/timeline/api-2.3.0/timeline-api.js?bundle=true"type="text/javascript"></script>

    <scriptsrc="local_data2.js" type="text/javascript"></script>

    <divid='tl'></div>

    

2.编写加载函数,并在网页中调用该函数

    <script>       

        var tl;

        function onLoad() {

            var tl_el =document.getElementById("tl");

            var eventSource1 = newTimeline.DefaultEventSource();

           

            var theme1 =Timeline.ClassicTheme.create();

            theme1.autoWidth = true; // Set theTimeline's "width" automatically.

                                     // SetautoWidth on the Timeline's first band's theme,

                                     // willaffect all bands.

            theme1.timeline_start = newDate(Date.UTC(1980, 0, 1));

            theme1.timeline_stop  = new Date(Date.UTC(2150, 0, 1));

           

            var d =Timeline.DateTime.parseGregorianDateTime("1980")

            var bandInfos = [

                Timeline.createBandInfo({

                              45, // set to a minimum, autoWidthwill then adjust

                    intervalUnit:   Timeline.DateTime.DECADE,

                    intervalPixels: 200,

                    eventSource:    eventSource1,

                    date:           d,

                    theme:          theme1,

                    layout:         'original'  // original, overview, detailed

                })

            ];

                                                           

            // create the Timeline

            tl = Timeline.create(tl_el,bandInfos, Timeline.HORIZONTAL);

           

            var url = '.'; // The base url forimage, icon and background image

                           // references in thedata

           eventSource1.loadJSON(timeline_data, url); // The data was stored intothe

    每日一道理
书,各种各样的书。书,寄托着人类热切的希望;书,蕴含着人类丰富的感悟。提起书,会有说不完的话语……

                                                      // timeline_data variable.

            tl.layout(); // display theTimeline

        }

       

        var resizeTimerID = null;

        function onResize() {

            if (resizeTimerID == null) {

                resizeTimerID =window.setTimeout(function() {

                    resizeTimerID = null;

                    tl.layout();

                }, 500);

            }

        }

   </script>

    调用该函数:<body onload="onLoad();"onresize="onResize();">

    

3.编写包括事件的JSON文件

    vartimeline_data = {  // save as a globalvariable

    'dateTimeFormat':'iso8601',

    'wikiURL':"http://simile.mit.edu/shelf/",

    'wikiSection':"Simile Cubism Timeline",

    'events' : [

         {'start': '1987',

        'title': 'Birthday of gongqingkui',

        'description': 'This is description',

        'image':'http://portrait7.sinaimg.cn/1150968582/blog/180',

        'link':'http://blog.sina.com.cn/gongqingkui',

         'icon' :"dark-red-circle.png",       

        'color' : 'red',

        'textColor' : 'green'

        },

         {'start':'1986',

         'end':'1990',

         'isDuration':true,

         'title':'aaa',

         //'tapeImage': 'blue_stripes.png',

        'tapeRepeat': 'repeat-x',

        'caption': "This is the event'scaption attribute.",

        'classname': 'hot_event'         

         },

    ]

    }

    该JSON数据目前包括一个点事件和一个段时光。

    4.加载效果

    数据和展示

    这是最简略的使用方法,一些详细的例子在这里http://simile-widgets.org/timeline/examples/index.html。与这个相似的一个应用timeplot[2]可以画时光相关的数据直方图,效果如下。
