By default Bullet Graph displays Tooltip when mouse is hovered over feature measure bar. Tooltip is enabled or disabled using visible property in tooltipSettings.

Bullet Graph supports Tooltip template instead of default Tooltip to customize the appearance and contents of Tooltip. The Tooltip template should be a <div> element with display set to ‘none’, so it is displayed only when mouse is placed on feature measure bar. The id value of the <div> element should be provided as value to the template property in tooltipSettings of Bullet Graph to display the customized <div> element as Tooltip instead of default Tooltip. The values displayed in default Tooltip such as current value, target value and category are accessed in template <div> element by using , and respectively.

HTML

<div id="BulletGraphTooltip" style="display:none; width:125px; padding-top: 10px; padding-bottom:10px; color: blue"> 
    <div align="center" style="color:blue; font-weight:bold"> Sales </div> 
    <table style="color:green"> <tr> <td> Current </td> <td> : </td> </tr> <tr> <td> Target </td> <td> : </td> </tr> </table> 
</div>

<ej-bulletgraph id="bullet1" [height]=150 [value]=8 [comparativeMeasureValue]=5 
      [tooltipSettings.visible]="true" tooltipSettings.template="BulletGraphTooltip">         
       
</ej-bulletgraph>

The following screenshot displays Bullet Graph with a customized Tooltip including a header and contents such as current value and target value in different colors.
