fusioncharts出图

昨天下午加今天上午一直在调程序

结果调到最后，发现所有的问题无外乎两种

1、需要的文件没有导入

2、中文乱码问题

 

json里所有的数据都是没编码的，所以如果要写中文的话，需要在前面加上u

 

利用数据出图代码

html

 

<div id="chart-bandwidth"></div>

 

 $('#submit').click(function() {
            var day = $('#beginDate').val();
            var nodename = $('#nodename').find("option:selected").text();
            if (nodename == "0") {
                return;
            }
            FusionCharts._fallbackJSChartWhenNoFlash();
            var chartBindwidth = new FusionCharts("/static/swf/MSCombiDY2D.swf",
                    "cd", "100%", "300", "0", "1");
            var urlBigNode = "/bignode/bandwidth/";
            urlBigNode += "?nodename="+nodename;
            urlBigNode += "%26beginDate="+day;
            chartBindwidth.setJSONUrl(urlBigNode);
            chartBindwidth.render("chart-bandwidth");
        });

 

views.py

 

data = Bignode.objects.filter(**args).order_by("time")
    mscombidy2d = MSCombiDY2D(u"大节点带宽", beginDate)
    mscombidy2d.categories = {"category": [{"name": d.time.strftime("%H:%M")} for d in data]}
    print mscombidy2d.categories
    mscombidy2d.dataset = [
            {"seriesname": u"剩余带宽", "parentyaxis": "P", "color": "5a885e",
             "data": [{"value": "%s" %(d.remainBandwidth,)} for d in data]
        },

        }
    ]
    res = json.dumps(mscombidy2d.to_dict(), ensure_ascii=False, sort_keys=True, indent=4)
    return HttpResponse(res)
