The problem is that you use id
in a template: id
must be unique.
Change id
by class
template: '<span class="sparkline"style="line-height: 60px ; padding: 0 5px 0spx ; text-align: center" ></span>'
and then in the initialization use:
$(".sparkline").kendoSparkline({...});
instead of:
$("#sparkline").kendoSparkline({});
