# Step Line Chart \[Deprecated]

## **How to display step line 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

{% tabs %}
{% tab title="C#" %}

```csharp
private void render_step_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_stepLine); 
      
  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);

}
```

{% endtab %}

{% tab title="VB.NET" %}

```
```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="C#" %}

```csharp
void render()
{

    Bunifu.Dataviz.WinForms.BunifuDatavizBasic canvas 
            = new Bunifu.Dataviz.WinForms.BunifuDatavizBasic.Canvas();
            
    Bunifu.DataViz.WinForms.DataPoint datapoint1;            
    bunifuDataViz1.colorSet.Add(Color.Black); 
                  
    datapoint1 = new Bunifu.Dataviz.WinForms.BunifuDatavizBasic.DataPoint(
        Bunifu.Dataviz.WinForms.BunifuDatavizBasic._type.Bunifu_stepLine);                      
    
    Random 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.Render(canvas);    

}
```

{% endtab %}

{% tab title="VB.NET" %}

Private Sub render()
    
    Dim canvas As Bunifu.Dataviz.WinForms.BunifuDatavizBasic.Canvas

    Dim random As Random = New Random()
    datapoint1.addLabely("MON", random.[Next](0, 50).ToString())
    datapoint1.addLabely("TUE", random.[Next](0, 50).ToString())

    datapoint1.addLabely("SAT", random.[Next](0, 50).ToString())
    datapoint1.addLabely("SUN", random.[Next](0, 50).ToString())
    
    canvas.addData(datapoint1)

End Sub

{% endtab %}
{% endtabs %}

In order to create a step line 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. 

Should you have feedback or suggestions please send us via chat on the bottom right corner of the screen.
