Pie Chart [Deprecated]

Easily use pie charts to show proportions in percentage form of categories of data. The full circle represents cumulative of all sections.

How to display pie 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_pie

C# code

private void render_pie_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_pie);   
  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   
  //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.BunifuDataViz._type.Bunifu_pie)
    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 pie 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.
