Area Chart [Deprecated]

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
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
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())
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.
