Sparkline tooltip format

[rwb]

I am finding that the tooltip shown is not what is produced by the tooltip.template.

Hello,

This happens because the Sparkline uses a shared tooltip by default, which is configured through the Chart tooltip option (as opposed to series.tooltip). If you want your template to take effect, disable the shared tooltip:

$('#sparklike').kendoSparkline({
  chartArea: {
    width: 300,
    height: 75,
  },
  series: [{
    field: 'value',
    type: "column",
    color: '#1A4B78',
    tooltip: {
      template: 'Period #= dataItem.period # <br /> £#= dataItem.value #'
    }
  }],
  valueAxis: {min: 0},
  dataSource: new kendo.data.DataSource({
    data: [
      {'period': '2017-1', value: 12},
      { 'period': '2017-2', value: 12},
      { 'period': '2017-3', value: 12},
      { 'period': '2017-4', value: 12},
      { 'period': '2017-5', value: 12},
      { 'period': '2017-6', value: 12},
      { 'period': '2017-7', value: 12},
      { 'period': '2017-8', value: 12},
      { 'period': '2017-9', value: 16},
      { 'period': '2017-10', value: 12 },
      { 'period': '2017-11', value: 16 },
      { 'period': '2017-12', value: 16 },
      { 'period': '2017-13', value: 16 }
    ]
  }),
  categoryAxis: { field: 'period'},
  tooltip: {
    shared: false
  }
});
