Getting Started with the ASP.NET MVC Accumulation Chart Control

21 Jul 20266 minutes to read

This section briefly explains how to add the Syncfusion® ASP.NET MVC Accumulation Chart control to an ASP.NET MVC application using Visual Studio.

Prerequisites

Refer to the System requirements for ASP.NET MVC controls before creating the application.

Create an ASP.NET MVC application with HTML helper

You can create an ASP.NET MVC application using either of the following options:

Install the ASP.NET MVC NuGet package

To add Syncfusion® ASP.NET MVC controls in the application, open the NuGet Package Manager in Visual Studio by selecting (Tools → NuGet Package Manager → Manage NuGet Packages for Solution). Search for Syncfusion.EJ2.MVC5 and install it.

Alternatively, you can use the Package Manager Console by navigating to:
Tools → NuGet Package Manager → Package Manager Console, and then run the following command:

Install-Package Syncfusion.EJ2.MVC5 -Version 34.1.29

NOTE

Syncfusion® ASP.NET MVC controls are available on nuget.org. Refer to the NuGet packages topic to learn more about installing NuGet packages in various operating system environments. The Syncfusion.EJ2.MVC5 NuGet package depends on Newtonsoft.Json for JSON serialization and Syncfusion.Licensing for validating the Syncfusion® license key.

Add the namespace

Add the Syncfusion.EJ2 namespace reference in the Web.config file available in the Views folder.

<namespaces>
    <add namespace="Syncfusion.EJ2" />
</namespaces>

Add script resources

Add the script reference inside the <head> element of the ~/Views/Shared/_Layout.cshtml file as follows.

<head>
    ...
    <!-- Syncfusion ASP.NET MVC controls scripts -->
    <script src="https://cdn.syncfusion.com/ej2/34.1.29/dist/ej2.min.js"></script>
</head>

NOTE

Refer to the Adding Script Reference topic to learn different approaches for adding script references in an ASP.NET MVC application.

Register the Syncfusion® Script Manager

Register the script manager EJS().ScriptManager() at the end of the <body> element in the ~/Views/Shared/_Layout.cshtml file as follows.

<body>
    ...
    <!-- Syncfusion ASP.NET MVC Script Manager -->
    @Html.EJS().ScriptManager()
</body>

Build the Accumulation Chart

This section walks through adding the Accumulation Chart control to ~/Views/Home/Index.cshtml and progressively binding data to it from ~/Controllers/HomeController.cs.

Step 1: Add the accumulation chart control

Add the Syncfusion® ASP.NET MVC Accumulation Chart control to the ~/Views/Home/Index.cshtml page.

@Html.EJS().AccumulationChart("container").Render()

Press Ctrl + F5 on Windows or ⌘ + F5 on macOS to run the application. The Accumulation Chart control will be rendered as an empty placeholder in the default web browser.

Step 2: Bind data to the chart

By default, a pie series is rendered when JSON data is assigned to the series using the dataSource property. Map the field names in the JSON data to the xName and yName properties of the series. The complete ~/Views/Home/Index.cshtml and ~/Controllers/HomeController.cs after this step are shown below.

@(Html.EJS().AccumulationChart("container")
    .LegendSettings(legend => legend.Visible(false))
    .Series(series =>
    {
        series.XName("xValue")
            .YName("yValue")
            .DataSource(ViewBag.dataSource)
            .Add();
    })
    .Render()
)
public ActionResult Index()
{
    List<PieChartData> chartData = new List<PieChartData>
    {
        new PieChartData { xValue = "Chrome", yValue = 15, text = "15", fill = "#00BDAE" },
        new PieChartData { xValue = "UC Browser", yValue = 22, text = "22", fill = "#404041" },
        new PieChartData { xValue = "iPhone", yValue = 32, text = "32", fill = "#357CD2" },
        new PieChartData { xValue = "Safari", yValue = 31, text = "31", fill = "#E56590" },
        new PieChartData { xValue = "Firefox", yValue = 29, text = "29", fill = "#F8B883" },
        new PieChartData { xValue = "Edge", yValue = 24, text = "24", fill = "#70AD47" },
        new PieChartData { xValue = "Others", yValue = 18, text = "18", fill = "#D77FB3" }
    };
    ViewBag.dataSource = chartData;
    return View();
}
public class PieChartData
{
    public string xValue;
    public double yValue;
    public string text;
    public string fill;
}

Press Ctrl + F5 on Windows or ⌘ + F5 on macOS to run the application. The Syncfusion® ASP.NET MVC Accumulation Chart control will be rendered in the default web browser.

Explore the sample on GitHub to understand how this getting started example works.

Troubleshooting

If the Accumulation Chart control does not render as expected, review the following common issues and their resolutions.

  • “Unlicensed” watermark appears on the page — The Syncfusion.Licensing package is installed but the license key has not been registered. Register the license key in ~/App_Start/FilterConfig.cs (or Program.cs) and rebuild. See Registering the Syncfusion license key.

  • “Script Manager is not defined” or scripts run twice — @Html.EJS().ScriptManager() was not added, or was added more than once. Ensure ScriptManager is registered exactly once at the end of <body> in _Layout.cshtml.

  • Chart renders but no data points appear — XName / YName do not match the property names in the data source. Property names are case-sensitive; verify they match the JSON field names exactly (e.g., x, y).

  • Newtonsoft.Json reference error after upgrade — Syncfusion.EJ2.MVC5 requires a specific Newtonsoft.Json version. Install a compatible Newtonsoft.Json version (≥ 12.0.2) via NuGet.
