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());                    


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.
