Area Chart

Show data trends with area chart
Simply represent data as a simple filled in area with Bunifu Area Chart.  With area chart you show trends over a given period of time.  
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_area
C# code

private void render_area(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_area);   
 
 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.BunifuDatavizBasic.DataPoint
    bunifuDataViz1.colorSet.Add(Color.Black)
    datapoint1 = New Bunifu.Dataviz.WinForms.BunifuDatavizBasic.DataPoint(Bunifu.Dataviz.WinForms.BunifuDatavizBasic._type.Bunifu_area)
    
    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 your 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 is contains 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 of your data in your application.
