# Step Area Chart \[Deprecated]

## **How to display step area 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. 

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

```csharp
private void render_step_area_Click(object sender, EventArgs e)
{   
    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_stepArea);   
    
    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()
    
    Dim canvas As Bunifu.Dataviz.WinForms.BunifuDatavizBasic.Canvas = New Bunifu.Dataviz.WinForms.BunifuDatavizBasic.Canvas()
    
    Dim datapoint1 As Bunifu.DataViz.WinForms.DataPoint
    
    bunifuDataViz1.colorSet.Add(Color.Black)
    
    datapoint1 = New Bunifu.Dataviz.WinForms.BunifuDatavizBasic.DataPoint(Bunifu.Dataviz.WinForms.BunifuDatavizBasic._type.Bunifu_stepArea)
    
    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 step area chart we need the following controls:

*  **Bunifu Data Viz** - This is the container for our chart
*  **Bunifu Canvas** - This is the middle layer between the data viz (container) and the dataset
*  **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.
