Stacked Column Chart [Deprecated]

Stacked column chart is useful for comparison purposes and visualizes data series stacked on top of one another vertically.

It is great when visualizing change in two multiple variables.

How to display stacked 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_stacked_column

C# code

C#

private void render()
{
    var canvas = new Bunifu.Dataviz.WinForms.BunifuDatavizAdvanced.Canvas();
    var datapoint = new Bunifu.Dataviz.WinForms.BunifuDatavizAdvanced.DataPoint(Bunifu.Dataviz.WinForms.BunifuDatavizAdvanced._type.Bunifu_stackedColumn);
    
    datapoint.addxy("new Date (2002,11,10)", new JArray(16.23, 17.99).ToString());
    datapoint.addxy("new Date (2002, 11, 9)", new JArray(15.95, 19.25).ToString());
    datapoint.addxy("new Date (2002, 11, 8)", new JArray(11.30, 16.88).ToString());
    datapoint.addxy("new Date (2002, 11, 7)", new JArray(13.29, 14.28).ToString());
    datapoint.addxy("new Date (2002, 11, 6)", new JArray(15.23, 16.45).ToString());
    datapoint.addxy("new Date (2002, 11, 5)", new JArray(13.70, 16.50).ToString());
    datapoint.addxy("new Date (2002, 11, 4)", new JArray(17.50, 19.00).ToString());
    datapoint.addxy("new Date (2002, 11, 3)", new JArray(19.50, 20.85).ToString());
    datapoint.addxy("new Date (2002, 11, 2)", new JArray(20.07, 21.44).ToString());
    datapoint.addxy("new Date (2002, 11, 1)", new JArray(25.00, 26.70).ToString());
   
    canvas.addData(datapoint);
    bunifuDataViz1.Render(canvas);
    
}

VB.NET

Private Sub render()
    
    Dim canvas = New Bunifu.DataViz.WinForms.Canvas()
    Dim datapoint = New Bunifu.DataViz.WinForms.DataPoint(Bunifu.DataViz.WinForms.BunifuDataViz._type.Bunifu_stackedColumn)
    
    datapoint.addxy("new Date (2002,11,10)", New JArray(16.23, 17.99).ToString())
    datapoint.addxy("new Date (2002, 11, 9)", New JArray(15.95, 19.25).ToString())
    datapoint.addxy("new Date (2002, 11, 8)", New JArray(11.30, 16.88).ToString())
    datapoint.addxy("new Date (2002, 11, 7)", New JArray(13.29, 14.28).ToString())
    datapoint.addxy("new Date (2002, 11, 6)", New JArray(15.23, 16.45).ToString())
    datapoint.addxy("new Date (2002, 11, 5)", New JArray(13.70, 16.50).ToString())
    datapoint.addxy("new Date (2002, 11, 4)", New JArray(17.50, 19.00).ToString())
    datapoint.addxy("new Date (2002, 11, 3)", New JArray(19.50, 20.85).ToString())
    datapoint.addxy("new Date (2002, 11, 2)", New JArray(20.07, 21.44).ToString())
    datapoint.addxy("new Date (2002, 11, 1)", New JArray(25.00, 26.70).ToString())
    
    canvas.addData(datapoint)
    bunifuDataViz1.Render(canvas)
    
End Sub

In order to display a Bunifu Stacked Column 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 contains the data that we want to represent, as pairs of X and Y coordinates

Bunifu Stacked Column simply works by creating 2 data point objects, one for the “low” set of points and one for the “high” set of points. The control will know automatically to adjust the width of the lines to match the specified data points.

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.
