Default tooltip

By default, tooltip is not visible. The tooltip can be enabled by setting the Enable property in TooltipSettings to true.

CSHTML

@(Html.EJS().Chart3D("container").WallColor("transparent").EnableRotation(true).Rotation(7).Tilt(10).Depth(100)
   .Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("month").
      YName("sales").
      DataSource(ViewBag.dataSource).
      Add();
   })
   .PrimaryXAxis(px => 
      px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
      .LabelPlacement(Syncfusion.EJ2.Charts.LabelPlacement.BetweenTicks).LabelRotation(-45)
   )
   .Tooltip(tp => tp.Enable(true))
   .Render())

Default-tooltip.cs

public ActionResult Index()
{
    List<ChartData> chartData = new List<ChartData>
    {
        new ChartData { month= "Jan", sales= 35 },
        new ChartData { month= "Feb", sales= 28 },
        new ChartData { month= "Mar", sales= 34 },
        new ChartData { month= "Apr", sales= 32 },

}

Fixed tooltip

By default, tooltip track the mouse movement, but the tooltip can be set in fixed position by using the Location property.

CSHTML

@(Html.EJS().Chart3D("container").WallColor("transparent").EnableRotation(true).Rotation(7).Tilt(10).Depth(100)
   .Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("month").
      YName("sales").
      DataSource(ViewBag.dataSource).
      Add();
   })
   .PrimaryXAxis(px => 
      px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
      .LabelPlacement(Syncfusion.EJ2.Charts.LabelPlacement.BetweenTicks).LabelRotation(-45)
   )
   .Tooltip(tp => tp.Enable(true).Location(lc => lc.X(120).Y(20)))
   .Render())

Fixed-tooltip.cs

public ActionResult Index()
{
    List<ChartData> chartData = new List<ChartData>
    {
        new ChartData { month= "Jan", sales= 35 },
        new ChartData { month= "Feb", sales= 28 },
        new ChartData { month= "Mar", sales= 34 },
        new ChartData { month= "Apr", sales= 32 },
        new ChartData { month= "May", sales= 40 },
        new ChartData { month= "Jun", sales= 32 },
        new ChartData { month= "Jul", sales= 35 },
        new ChartData { month= "Aug", sales= 55 },
        new ChartData { month= "Sep", sales= 38 },
        new ChartData { month= "Oct", sales= 30 },
        new ChartData { month= "Nov", sales= 25 },
        new ChartData { month= "Dec", sales= 32 }
    };
    ViewBag.dataSource = chartData;
    return View();
}
public class ChartData
{
    public string month;
    public double sales;
}

CSHTML

@(Html.EJS().Chart3D("container").WallColor("transparent").EnableRotation(true).Rotation(7).Tilt(10).Depth(100)
   .Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("month").
      YName("sales").
      Name("Month").

      .LabelPlacement(Syncfusion.EJ2.Charts.LabelPlacement.BetweenTicks).LabelRotation(-45)
   )
   .Tooltip(tp => tp.Enable(true).Header("Unemployment").Format("<b>${series.name} : ${point.y}</b>"))
   .Render())

    List<ChartData> chartData = new List<ChartData>
    {
        new ChartData { month= "Jan", sales= 35 },
        new ChartData { month= "Feb", sales= 28 },

public class ChartData

CSHTML

@(Html.EJS().Chart3D("container").WallColor("transparent").EnableRotation(true).Rotation(7).Tilt(10).Depth(100)
   .Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("month").
      YName("sales").
      DataSource(ViewBag.dataSource).
      Add();
   })
   .PrimaryXAxis(px => 
      px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
      .LabelPlacement(Syncfusion.EJ2.Charts.LabelPlacement.BetweenTicks).LabelRotation(-45)
   )
   .Tooltip(tp => tp.Enable(true).Template("#Unemployment"))
   .Render())

Template.cs

public ActionResult Index()
{
    List<ChartData> chartData = new List<ChartData>
    {
        new ChartData { month= "Jan", sales= 35 },
        new ChartData { month= "Feb", sales= 28 },
        new ChartData { month= "Mar", sales= 34 },
        new ChartData { month= "Apr", sales= 32 },
        new ChartData { month= "May", sales= 40 },
        new ChartData { month= "Jun", sales= 32 },
        new ChartData { month= "Jul", sales= 35 },
        new ChartData { month= "Aug", sales= 55 },
        new ChartData { month= "Sep", sales= 38 },
        new ChartData { month= "Oct", sales= 30 },
        new ChartData { month= "Nov", sales= 25 },
        new ChartData { month= "Dec", sales= 32 }
    };
    ViewBag.dataSource = chartData;
    return View();
}
public class ChartData
{
    public string month;
