# Doughnut Chart \[Deprecated]

{% hint style="info" %}
**PRO TIP!** Use a doughnut chart with few items to avoid squeezing thus making items invisible.&#x20;
{% endhint %}

## **How to display doughnut chart using Bunifu Dataviz**

Simply locate Bunifu Dataviz control in your toolbox and drag it to the location on your form where you would like to display it.&#x20;

We will use button click event handler to display our chart called render\_doughnut

**C# code**

```csharp
private void render_doughnut(){   

   var r = new Random();   
   var canvas = new Bunifu.Dataviz.WinForms.BunifuDatavizBasic.Canvas();
      
   var datapoint = new Bunifu.Dataviz.WinForms.BunifuDatavizBasic.DataPoint(Bunifu.Dataviz.WinForms.BunifuDatavizBasic._type.Bunifu_doughnut);   
   
   datapoint.addLabely("SUN", r.Next(0, 100).ToString());   
   datapoint.addLabely("MON", r.Next(0, 100).ToString());  
   datapoint.addLabely("TUE", r.Next(0, 100).ToString());   
   datapoint.addLabely("WED", r.Next(0, 100).ToString());   
   datapoint.addLabely("THU", r.Next(0, 100).ToString());   
   datapoint.addLabely("FRI", r.Next(0, 100).ToString());   
   datapoint.addLabely("SAT", r.Next(0, 100).ToString());   
   
   // Add data sets to canvas   
   canvas.addData(datapoint);   
   //render canvas   
   bunifuDataViz1.Render(canvas); 

}
```

**VB.NET code**

```

Private Sub render_doughnut()
    
    Dim canvas As Bunifu.Dataviz.WinForms.BunifuDatavizBasic.Canvas = New Bunifu.Dataviz.WinForms.BunifuDatavizBasic.Canvas()
    Dim datapoint1 As Bunifu.Dataviz.WinForms.BunifuDatavizBasic.DataPoint
    
    bunifuDataViz1.colorSet.Add(Color.Black)
    datapoint1 = New Bunifu.Dataviz.WinForms.BunifuDatavizBasic.DataPoint(Bunifu.Dataviz.WinForms.BunifuDatavizBasic._type.Bunifu_doughnut)
    
    Dim random As Random = New Random()
    datapoint1.addLabely("MON", random.[Next](0, 50).ToString())
    datapoint1.addLabely("TUE", random.[Next](0, 50).ToString())
    datapoint1.addLabely("WED", random.[Next](0, 50).ToString())
    datapoint1.addLabely("THU", random.[Next](0, 50).ToString())
    datapoint1.addLabely("FRI", random.[Next](0, 50).ToString())
    datapoint1.addLabely("SAT", random.[Next](0, 50).ToString())
    datapoint1.addLabely("SUN", random.[Next](0, 50).ToString())
    
    canvas.addData(datapoint1)
    bunifuDataViz1.Renderint2))

End Sub

```

In order to display Bunifu Doughnut chart we need the following controls:

* &#x20;**Bunifu Data Viz** - This is the container for our chart
* &#x20;**Bunifu Canvas** - This is the middle layer between the data viz (container) and the dataset
* &#x20;**Bunifu Data Point** - This will contain the data that we want to represent as pairs of X and Y coordinates

On running the code you should see something like this:

That's it!

We hope Bunifu Dataviz will help you bring out the best data visualization for your data in your application.&#x20;
