Getting started with ASP.NET Core Smith Chart control

This section explains you the steps required to create a Smithchart and demonstrate the basic usage of the Smithchart control.

Prerequisites

To get start with ASP.NET Core application, need to ensure the following software to be installed on the machine.

  • Visual Studio 2017
  • DotNet Core 2.0

Setup ASP.NET Core application with Essential JS 2 for ASP.NET Core

The following steps to create ASP.NET Core Application.

Step 1: Create ASP.NET Core Web Application with default template project in Visual Studio 2017.

Alt text

Step 2: Once your project created. We need to add Syncfusion EJ2 package into your application by using Nugget Package Manager.

Open the nuGet package manager.

Alt text

Install the Syncfusion.EJ2 package to the application

Alt text

After Installation complete this will included in the project. You can refer it from the Project Assembly Reference.

We need to install NewtonSoft.JSON as dependency since it Syncfusion.EJ2 dependent to NewtonSoft.JSON package.

Step 3: Open the _ViewImports.cshtml to import Syncfusion.EJ2 package.

@addTagHelper *, Syncfusion.EJ2

Step 4: Add client side resource through CDN or local package in the layout page _Layout.cshtml.

@* Syncfusion Essential JS 2 Scripts *@
<script src="https://cdn.syncfusion.com/ej2/dist/ej2.min.js"></script>

Step 5: Adding Script Manager in layout page _Layout.cshtml.

<ejs-scripts></ejs-scripts>

Step 6: Add the below code to your Index.cshtml view page which is present under Views/Home folder, to initialize the smith chart.

@using Syncfusion.EJ2;
 <ejs-smithchart id="smithchart">
</ejs-smithchart>

Add series to Smith chart

The Smith chart has the following two type of specification for adding series:

  • dataSource - Data object can be bound directly by specifying the resistance and reactance values.
  • points - Collection of resistance and reactance values can be bound directly to render the series.

The following two ways demonstrate adding two series to the Smith chart.

  • First series Transmission1 shows dataSource bound series.
  • Second series Transmission2 shows points bound series.
