javascript - Chart.js label value -

-

i have question, have idea, how change chart.js label value format?

screenshot: enter image description here

how change it, show not "acw (sec): 10" but "acw: 10sec"

code looks like: 

var doughnutdataacw = [                 {                     value: <?php echo gmdate("s", $singleacw); ?>,                     color: "#35df6b",                     highlight: "#06cc45",                     label: "acw (sec)"                 }

you can use tooltiptemplate option:

    tooltiptemplate: "acw: <%=value%>sec"

if need acw part come label:

    tooltiptemplate: "<%=label%>: <%=value%>sec"
