Create Your First Chart
Let's create a Column 2D chart showing the "Most popular programming language".
The chart will look as shown below:
FusionCharts will load here..
Click here to edit the column chart.
The data for the above chart is shown in the table below:
Programming Language | Users |
---|---|
Java | 62000 |
Python | 46000 |
JavaScript | 38000 |
C++ | 31000 |
C# | 27000 |
PHP | 14000 |
Perl | 14000 |
Now that you have the tabular data ready, let's see how to render the chart.
Render the chart
Create the FirstChart.aspx.cs
file and do the following:
- Include the
FusionCharts.DataEngine
andFusionCharts.Visualization
.dll files. - Create
DataTable
. - Retrieve data using database query.
- Set server name.
- Set
DataBase
name. - Retrieve data from database and store it in a
DataTable
object. - Create a
StaticSource
using theDataTable
. - Create an instance of
DataModel
class. - Add
DataSource
to theDataModel
. - Instantiate Column Chart
- Set chart width and height
- Set
DataModel
instance as the data source of the chart. - Set chart title.
- Finally, use a container using
<div>
to render the chart.
The code is shown below:
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using FusionCharts.DataEngine;
using FusionCharts.Visualization;
namespace FusionChartsVisualisationWebFormsSamples.Samples
{
public partial class FirstChart: System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
DataTable ChartData = new DataTable();
ChartData.Columns.Add("Programming Language", typeof(System.String));
ChartData.Columns.Add("Users", typeof(System.Double));
ChartData.Rows.Add("Java",62000);
ChartData.Rows.Add("Python",46000);
ChartData.Rows.Add("Javascript",38000);
ChartData.Rows.Add("C++",31000);
ChartData.Rows.Add("C#",27000);
ChartData.Rows.Add("PHP",14000);
ChartData.Rows.Add("Perl",14000);
// Create static source with this data table
StaticSource source = new StaticSource(ChartData);
// Create instance of DataModel class
DataModel model = new DataModel();
// Add DataSource to the DataModel
model.DataSources.Add(source);
// Instantiate Column Chart
Charts.ColumnChart column = new Charts.ColumnChart("first_chart");
// Set Chart's width and height
column.Width.Pixel(700);
column.Height.Pixel(400);
// Set DataModel instance as the data source of the chart
column.Data.Source = model;
// Set Chart Title
column.Caption.Text = "Most popular programming language";
// Sset chart sub title
column.SubCaption.Text = "2017-2018";
// set XAxis Text
column.XAxis.Text = "Programming Language";
// Set YAxis title
column.YAxis.Text = "User";
column.ThemeName = FusionChartsTheme.ThemeName.FUSION;
// Render the chart to 'Literal1' literal control
Literal1.Text = column.Render();
}
}
}
The .aspx
template for the above sample is shown below:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<script type="text/javascript" src="//cdn.fusioncharts.com/fusioncharts/latest/fusioncharts.js"></script>
<script type="text/javascript" src="//cdn.fusioncharts.com/fusioncharts/latest/themes/fusioncharts.theme.fusion.js"></script>
<form id="form1" runat="server">
<div>
<asp:Literal ID="Literal1" runat="server"></asp:Literal>
</div>
</form>
</body>
</html>
That's it! Your first chart is ready.
