Simply use column chart to show comparison. Bunifu Column Chart displays data using vertical bars

How to display column 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_column
C# code
1
private void render_column()
2
{

4
var r = new Random();
5
var canvas = new Bunifu.Dataviz.WinForms.BunifuDatavizBasic.Canvas();
6
var datapoint = new Bunifu.Dataviz.WinForms.BunifuDatavizBasic.DataPoint(Bunifu.Dataviz.WinForms.BunifuDatavizBasic._type.Bunifu_column);
7
8
datapoint.addLabely("SUN", r.Next(0, 100).ToString());
9
datapoint.addLabely("MON", r.Next(0, 100).ToString());
10
datapoint.addLabely("TUE", r.Next(0, 100).ToString());
11
datapoint.addLabely("WED", r.Next(0, 100).ToString());
12
datapoint.addLabely("THU", r.Next(0, 100).ToString());
13
datapoint.addLabely("FRI", r.Next(0, 100).ToString());
14
datapoint.addLabely("SAT", r.Next(0, 100).ToString());

// Add data sets to canvas

canvas.addData(datapoint);

In order to display column 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.
