Getting Started with ASP.NET Core Sparkline Control
21 Dec 202214 minutes to read
This section briefly explains about how to include ASP.NET Core Sparkline control in your ASP.NET Core application using Visual Studio.
Prerequisites
System requirements for ASP.NET Core controls
Create ASP.NET Core web application with Razor pages
Install ASP.NET Core package in the application
Syncfusion ASP.NET Core controls are available in nuget.org. Refer to NuGet packages topic to learn more about installing NuGet packages in various OS environments. To add ASP.NET Core controls in the application, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.EJ2.AspNet.Core and then install it.
NOTE
The Syncfusion.EJ2.AspNet.Core NuGet package has dependencies, Newtonsoft.Json for JSON serialization and Syncfusion.Licensing for validating Syncfusion license key.
Add Syncfusion ASP.NET Core Tag Helper
Open ~/Views/_ViewImports.cshtml
file and import the Syncfusion.EJ2
TagHelper.
@addTagHelper *, Syncfusion.EJ2
Add style sheet
Checkout the Themes topic to learn different ways (CDN, NPM package, and CRG) to refer styles in ASP.NET Core application, and to have the expected appearance for Syncfusion ASP.NET Core controls. Here, the theme is referred using CDN inside the <head>
of ~/Pages/Shared/_Layout.cshtml
file as follows,
<head>
...
<!-- Syncfusion ASP.NET Core controls styles -->
<link rel="stylesheet" href="https://cdn.syncfusion.com/ej2/21.1.35/fluent.css" />
</head>
Add script reference
In this getting started walk-through, the required scripts are referred using CDN inside the <head>
of ~/Pages/Shared/_Layout.cshtml
file as follows,
<head>
...
<!-- Syncfusion ASP.NET Core controls scripts -->
<script src="https://cdn.syncfusion.com/ej2/21.1.35/dist/ej2.min.js"></script>
</head>
Register Syncfusion Script Manager
Open ~/Pages/Shared/_Layout.cshtml
page and register the script manager
<body>
...
<!-- Syncfusion ASP.NET Core Script Manager -->
<ejs-scripts></ejs-scripts>
</body>
Add ASP.NET Core Sparkline Control
Now, add the Syncfusion ASP.NET Core Sparkline tag helper in ~/Pages/Index.cshtml
page.
<ejs-sparkline id="sparkline">
</ejs-sparkline>
Bind data source to Sparkline
The dataSource
property is used for binding data source to the sparkline. This property takes the collection value as input. For example, the list of objects can be provided as input.
@{
...
var data = DataSource.GetData();
}
<div class="spark" align="center">
<ejs-sparkline id="sparkline" loaded="loaded" height="100px" width="70%" dataSource="data" xName="xval" yName="yval"></ejs-sparkline>
</div>
<style>
.spark {
border: 1px solid rgb(209, 209, 209);
border-radius: 2px;
width: 100%;
height: 100%;
}
</style>
<script>
function loaded(args)
{
window.sparkline = args.sparkline;
args.sparkline.loaded = null;
args.sparkline.refresh();
}
</script>
public class DataSource
{
public int x;
public string xval;
public double yval;
public static List<DataSource> GetData()
{
List<DataSource> data1 = new List<DataSource>();
data1.Add(new DataSource() { x = 0, xval = "2005", yval = 20090440 });
data1.Add(new DataSource() { x = 1, xval = "2006", yval = 20264080 });
data1.Add(new DataSource() { x = 2, xval = "2007", yval = 20434180 });
data1.Add(new DataSource() { x = 3, xval = "2008", yval = 21007310 });
data1.Add(new DataSource() { x = 4, xval = "2009", yval = 21262640 });
data1.Add(new DataSource() { x = 5, xval = "2010", yval = 21515750 });
data1.Add(new DataSource() { x = 6, xval = "2011", yval = 21766710 });
data1.Add(new DataSource() { x = 7, xval = "2012", yval = 22015580 });
data1.Add(new DataSource() { x = 8, xval = "2013", yval = 22262500 });
data1.Add(new DataSource() { x = 9, xval = "2014", yval = 22507620 });
return data1;
}
}
Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to run the app. Then, the Syncfusion ASP.NET Core Sparkline control will be rendered in the default web browser.
Change the type of Sparkline
You can change the sparkline type by setting the type
property to Line
, Column
, WinLoss
, Pie
, or Area
. Here, the sparkline type has been set to area
.
@{
...
var data = DataSource.GetData();
}
<div class="spark" align="center">
<ejs-sparkline id="sparkline" loaded="loaded" type="Area" height="100px" width="70%" dataSource="data" xName="xval" yName="yval"></ejs-sparkline>
</div>
<style>
.spark {
border: 1px solid rgb(209, 209, 209);
border-radius: 2px;
width: 100%;
height: 100%;
}
</style>
<script>
function loaded(args)
{
window.sparkline = args.sparkline;
args.sparkline.loaded = null;
args.sparkline.refresh();
}
</script>
public class DataSource
{
public int x;
public string xval;
public double yval;
public static List<DataSource> GetData()
{
List<DataSource> data1 = new List<DataSource>();
data1.Add(new DataSource() { x = 0, xval = "2005", yval = 20090440 });
data1.Add(new DataSource() { x = 1, xval = "2006", yval = 20264080 });
data1.Add(new DataSource() { x = 2, xval = "2007", yval = 20434180 });
data1.Add(new DataSource() { x = 3, xval = "2008", yval = 21007310 });
data1.Add(new DataSource() { x = 4, xval = "2009", yval = 21262640 });
data1.Add(new DataSource() { x = 5, xval = "2010", yval = 21515750 });
data1.Add(new DataSource() { x = 6, xval = "2011", yval = 21766710 });
data1.Add(new DataSource() { x = 7, xval = "2012", yval = 22015580 });
data1.Add(new DataSource() { x = 8, xval = "2013", yval = 22262500 });
data1.Add(new DataSource() { x = 9, xval = "2014", yval = 22507620 });
return data1;
}
}
Enable tooltip for Sparkline
The sparkline displays additional information through tooltip when the mouse is hovered over the sparkline. You can enable tooltip by setting the visible
property to true in tooltipSettings
object.
@{
...
var data = DataSource.GetData();
}
<div class="spark" align="center">
<ejs-sparkline id="sparkline" loaded="loaded" type="Area" height="100px" width="70%" dataSource="data" xName="xval" yName="yval">
<e-sparkline-tooltipsettings visible="true" format="${xval} : ${yval}"></e-sparkline-tooltipsettings>
</ejs-sparkline>
</div>
<style>
.spark {
border: 1px solid rgb(209, 209, 209);
border-radius: 2px;
width: 100%;
height: 100%;
}
</style>
<script>
function loaded(args)
{
window.sparkline = args.sparkline;
args.sparkline.loaded = null;
args.sparkline.refresh();
}
</script>
public class DataSource
{
public int x;
public string xval;
public double yval;
public static List<DataSource> GetData()
{
List<DataSource> data1 = new List<DataSource>();
data1.Add(new DataSource() { x = 0, xval = "2005", yval = 20090440 });
data1.Add(new DataSource() { x = 1, xval = "2006", yval = 20264080 });
data1.Add(new DataSource() { x = 2, xval = "2007", yval = 20434180 });
data1.Add(new DataSource() { x = 3, xval = "2008", yval = 21007310 });
data1.Add(new DataSource() { x = 4, xval = "2009", yval = 21262640 });
data1.Add(new DataSource() { x = 5, xval = "2010", yval = 21515750 });
data1.Add(new DataSource() { x = 6, xval = "2011", yval = 21766710 });
data1.Add(new DataSource() { x = 7, xval = "2012", yval = 22015580 });
data1.Add(new DataSource() { x = 8, xval = "2013", yval = 22262500 });
data1.Add(new DataSource() { x = 9, xval = "2014", yval = 22507620 });
return data1;
}
}
