Rendering FusionCharts in ASP.NET MVC Framework Using Razor View

  • Dishank Tiwari and Soumya Dutta
    • Razor is an ASP.NET programming syntax for developing dynamic web pages using the C# or Visual Basic.NET programming languages. The ASP.NET MVC framework is an alternative to the ASP.NET Web Forms pattern for developing web applications. In this post, we’ll go over a tutorial for using Razor View to render FusionCharts in an ASP.NET MVC framework-based application, as well as the basic requirements and steps for rendering FusionCharts. When creating Interactive Graphs and charts, you can use the ASP.NET FusionCharts plugin to help you replicate this tutorial.

    System Requirements

    To start rendering charts in ASP.NET MVC framework using razor view, make sure that you have the following components downloaded in the local machine:

    Rendering FusionCharts in the ASP.NET MVC Framework

    Rendering charts using FusionCharts in ASP.NET MVC Framework can be achieved easily with the help of the FusionCharts ASP.NET wrapper. Follow the steps given below to render charts in the ASP.NET MVC framework:

    Step 1

    Create a new project in ASP.NET application (click File->New->Project) and choose MVC from installed templates as shown in the image below: A directory will be created with structure as shown below:

    Step 2

    Include the fusioncharts.js and fusioncharts.charts.js libraries within script folder as shown in the image below:

    Step 3

    Insert Index.cshtml to Home folder under Views, as shown in the image below: Once done remove all the codes written in the file and include js files of FusionCharts in it. Include the following code in the <div> created: 
    <html>
<head>
    @{ ViewBag.Title = "Home Page"; }

    <script src="~/Scripts/fusioncharts.js"></script>
    <script src="~/Scripts/fusioncharts.charts.js"></script>
    <script src="~/Scripts/fusioncharts.theme.fint.js"></script>
</head>
<body>
    <center>
        <h2>Rendering Charts supported by FusionCharts in MVC5</h2>
        <div>
            @Html.Raw(ViewBag.mydata)
        </div>
    </center>
</body>
</html>

    Step 4

    Add FusionCharts.dll (as a reference) into the project to use FusionCharts ASP.NET wrapper. To add FusionCharts.dll as a reference:

    Step 5

    From the Reference Manager dialogue box, search for FusionCharts.dll in your local machine and add it into this box. Refer to the image below:

    Step 6

    Insert HomeController.cs in controllers folder and include FusionCharts namespace stated below:

    Step 7

    Create a method named createChart and define the return type as string. createChart will return the string fetched after calling Render function as shown below: 
    public string createChart() {
    string dat = "<chart caption='Customer Satisfaction Score' subcaption='Last week' lowerlimit='0' upperlimit='100' theme='fint'><colorrange><color minvalue='0' maxvalue='50' code='#e44a00'></color><color minvalue='50' maxvalue='75' code='#f8bd19'></color><color minvalue='75' maxvalue='100' code='#6baa01'></color></colorrange><dials><dial value='67'></dial></dials></chart>";
    Chart data = new Chart("angulargauge", "myChart", "600", "350", "xml", dat);
    return data.Render();
}

    Step 8

    In HomeController.cs, search for index method. In that define an attribute and initialize it with the return value of the defined createChart method. 
    ViewBag.mydata = createChart();

    Step 9

    Now, you are ready to render FusionCharts in your MVC framework. Press ctrl + f5 to run and check the output of the chart as shown in the image below: If you find any difficulty in rendering the chart or you see any error in your code, click here to download the complete source code of the sample project we have created for this tutorial.
