TOOLTIP STATIC POSITION

[David]

I need that the tooltip, appear in one position of the chart, in the chart or outside it
someone can do this in any moment

Hi David,

This can be achieved using the following approach: 

• Set visible: false to the default tooltip in Kendo UI Chart;
• In the seriesHover event call a function which sets the tooltip with a custom position.

• <script>
  $("#chart").kendoChart({
    //....
     tooltip: {
        visible: false
     },
     seriesHover: showTooltip
  });
  
  var showTooltip = function(e) {$("#chart .k-tooltip").html(e.value).show();
  }
  </script>
  
  <style>
  .k-tooltip{
     //custom position
  }​
  </style>

Hello David,

You could specify the tooltip position for each chart as specify its ID. I.e.: 

<style>
#chart1 .k-tooltip{
   //custom position
}​

#chart2 .k-tooltip{
   //custom position
}​

#chart3 .k-tooltip{
   //custom position
}​

....
</style>

If you are not familiar with CSS specificity I recommend reading this article in Smashing Magazine.

Works fine, 1 question still. How can I get the percentage value of the donut part I'm hovering over from the showTooltip function?
With the standard MVC code it's like: .Template("#= kendo.format('{0:P0}', percentage) #" + " score " + "#= category #")
But I can't get the percentage in the showTooltip function.

Hi Jurgen,

In order to achieve this you could define the format in the Chart's configuration. For example:

@(Html.Kendo().Chart(Model)
  //....
  .Tooltip(t => t.Visible(false).Format("{0:P0}%"))
  .Events(ev => ev.SeriesHover("showTooltip"))
)

<script>
  function showTooltip(e) { $("#chart .k-tooltip").html(kendo.format(e.series.tooltip.format, e.value) + " - " + e.category).show(); }
</script>

Let me know if this helps.

The CSS for a specific tooltip is no longer valid because the DIV that gets created for the tooltip is outside of the container now.

Hi David,

In the current Kendo UI Chart you could set custom position to the .k-chart-tooltip element. For example: 

.k-chart-tooltip {
   position: fixed !important;
   top: 0 !important;
   left: 0 !important;
}
