テーブルに20ミリオンの行があります。http: //www.jqplot.com/tests/date-axes.php (日付と時刻)を使用してタイムスタンプのグラフをプロットしようとしています。jqueryはプロットするデータの多くをどのように処理しますかそれ。2つの質問:
1.以下のコードから配列を作成するにはどうすればよいですか?
line1=[['2008-09-30',4], ['2008-10-30',6], ['2008-11-30',5], ['2008-12-30',9], ['2009-01-30',8]];`
2.この場合、コードを即興するにはどうすればよいですか?
def get_data(request):
cdr = Cdr.objects.values_list('start_of_call',flat=True)
context_instance=RequestContext(request, {}))
return render_to_response('cdr/get_data.html', context_instance=RequestContext(request, {'cdr':cdr}))
レンプレート:
<script class="code" type="text/javascript">
$(document).ready(function(){
{% for c in cdr %}
{{ c|date:"d M Y"}}
{% endfor %}
How to construct the below array line from for loop or using jquery methods
//var line1=[['2008-09-30',4], ['2008-10-30',6], ['2008-11-30',5], ['2008-12-30',9], ['2009-01-30',8]];
var plot1 = $.jqplot('chart1', [line1], {
title:'Default Date Axis',
axes:{xaxis:{renderer:$.jqplot.DateAxisRenderer}},
series:[{lineWidth:4, markerOptions:{style:'square'}}]
});
});
</script>
EDIT
line1=[['2008-09-30',4], ['2008-10-30',6], ['2008-11-30',5], ['2008-12-30',9], ['2009-01-30',8]];`
上記の行の4、6、5、9、8は時間です

CDR値:
