Step Line Chart [Deprecated]

Step line chart is derived from line chart and is used to display non-uniform changes and show periods with no data and as well as its magnitude.

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
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(
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
void render()
Bunifu.Dataviz.WinForms.BunifuDatavizBasic canvas
= new Bunifu.Dataviz.WinForms.BunifuDatavizBasic.Canvas();
Bunifu.DataViz.WinForms.DataPoint datapoint1;
datapoint1 = new Bunifu.Dataviz.WinForms.BunifuDatavizBasic.DataPoint(
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());
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(
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 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.
