Bubble Chart [Deprecated]
Bubble chart is derived from scatter chart and is used to emphasize the specific values in your chart using different bubble sizes.
How to display bubble 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_bubble_chart
C#
VB.NET
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_bubble);
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);
}
Private Sub render()
Dim canvas = New Bunifu.Dataviz.WinForms.BunifuDatavizAdvanced.Canvas()
Dim datapoint = New Bunifu.Dataviz.WinForms.BunifuDatavizAdvanced.DataPoint(Bunifu.Dataviz.WinForms.BunifuDatavizAdvanced._type.Bunifu_bubble)
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 bubble 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:
Also, if we change the line:
datapoint.addxy(r.Next(0, 100).ToString(), r.Next(10, 100).ToString());
with the following line
2 datapoint.addxy(i.ToString(), (1000 - i).ToString());
we will get the following result:
That's it!
We hope Bunifu Dataviz will help you bring out the best data visualization for your data in your application.
