我有图表和过滤器,所以如果我使用2016年1月到2016年5月的过滤日期范围,它会显示如下
但是当我再次按下提交时,它显示如下:
我的观点是,每次我提交时,传说都会添加更多传说。我每次提交时如何制作1个传奇?
这是我的代码

// Get context with jQuery - using jQuery's .get() method.
var ctx = $("#chart1").get(0).getContext("2d");
// This will get the first returned node in the jQuery collection.
var chart1 = new Chart(ctx).Line(data, options);
//generate the legend
var legend = chart1.generateLegend();
//and append it to your page somewhere
$('#chart1Legend').append(legend);
答案 0 :(得分:1)
在添加图例之前,您需要先清除chart1Legend
。
请尝试以下代码段。
$('#chart1Legend').empty();
$('#chart1Legend').append(legend);
希望这有帮助!
