This section explains you the steps required to populate the Chart with data, header, add data labels, legend and tooltips to the Chart. This section covers only the minimal features that you need to know to get started with the Chart.

Adding Chart Reference

Refer this article to know how to add Syncfusion® controls in Visual Studio projects through various way. You can also refer this link to know about the assemblies required for adding Chart to your project.

Initialize Chart

Import the SfChart namespace as shown below in your respective Page,

XAML

xmlns:syncfusion="using:Syncfusion.UI.Xaml.Charts"

C#

using Syncfusion.UI.Xaml.Charts;

VB.NET

Imports Syncfusion.UI.Xaml.Charts

Then initialize an empty chart with two axes as shown below,

XAML

<syncfusion:SfChart> 
      <syncfusion:SfChart.PrimaryAxis> 
           <syncfusion:CategoryAxis /> 
      </syncfusion:SfChart.PrimaryAxis> 
      <syncfusion:SfChart.SecondaryAxis> 
           <syncfusion:NumericalAxis/> 
      </syncfusion:SfChart.SecondaryAxis>
 </syncfusion:SfChart>

C#

SfChart chart = new SfChart();

CategoryAxis primaryAxis = new CategoryAxis();

chart.PrimaryAxis = primaryAxis; 
   
NumericalAxis secondaryAxis = new NumericalAxis();

chart.SecondaryAxis = secondaryAxis;

VB.NET

Dim chart As New SfChart()

Dim primaryAxis As New CategoryAxis () 

chart.PrimaryAxis = primaryAxis 

Dim secondaryAxis As New NumericalAxis ()  

chart.SecondaryAxis = secondaryAxis

Run the project and check if you get following output to make sure you have configured your project properly to add SfChart.

NOTE

SfChart supports default axes, so that these axes (PrimaryAxis and SecondaryAxis) will get generated automatically based upon the data bind to the chart, if you didn’t specify the axes explicitly.

Initialize view model

Now, let us define a simple data model that represents a data point in SfChart.

C#

public class Person   
{   
    public string Name { get; set; }

    public double Height { get; set; }
}

VB.NET

Public Class Person

    Public Property Name As String

    Public Property Height As Double

End Class

Next, create a view model class and initialize a list of Person objects as shown below,

C#

public class ViewModel  
{
      public List<Person> Data { get; set; }      

      public ViewModel()       
      {
            Data = new List<Person>()
            {
                new Person { Name = "David", Height = 180 },
                new Person { Name = "Michael", Height = 170 },
                new Person { Name = "Steve", Height = 160 },
                new Person { Name = "Joel", Height = 182 }
            }; 
       }
 }

VB.NET

Public Class ViewModel

    Public Property Data As List(Of Person)

    Public Sub New()
        Data = New List(Of Person)() From
        {
            New Person With {.Name = "David", .Height = 180},
            New Person With {.Name = "Michael", .Height = 170},
            New Person With {.Name = "Steve", .Height = 160},
            New Person With {.Name = "Joel", .Height = 182}
        }
    End Sub
End Class

Set the ViewModel instance as the DataContext of your Page; this is done to bind properties of ViewModel to SfChart.

NOTE

Add namespace of ViewModel class in your XAML page if you prefer to set DataContext in XAML.

XAML

<Page
    x:Class="ChartDemo.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:ChartDemo"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:syncfusion="using:Syncfusion.UI.Xaml.Charts"
    mc:Ignorable="d">

    <Page.DataContext>
        <local:ViewModel/>
    </Page.DataContext>

</Page>

C#

this.DataContext = new ViewModel();

VB.NET

Me.DataContext = New ViewModel()

Populate Chart with data

As we are going to visualize the comparison of heights in the data model, add ColumnSeries to SfChart.Series property, and then bind the Data property of the above ViewModel to the ColumnSeries.ItemsSource property as shown below.

NOTE

You need to set XBindingPath and YBindingPath properties, so that SfChart would fetch values from the respective properties in the data model to plot the series.

XAML

<syncfusion:SfChart>
   
  <syncfusion:SfChart.PrimaryAxis>
    
      <syncfusion:CategoryAxis Header="Name" />             
   
  </syncfusion:SfChart.PrimaryAxis>

  <syncfusion:SfChart.SecondaryAxis>
  
      <syncfusion:NumericalAxis Header="Height(in cm)" />                        

  </syncfusion:SfChart.SecondaryAxis>
    
   <syncfusion:ColumnSeries  ItemsSource="{Binding Data}" XBindingPath="Name" YBindingPath="Height" >
  </syncfusion:ColumnSeries>

 </syncfusion:SfChart>

C#

SfChart chart = new SfChart();

//Adding horizontal axis to the chart 

CategoryAxis primaryAxis = new CategoryAxis();

primaryAxis.Header = "Name";      

chart.PrimaryAxis = primaryAxis;


//Adding vertical axis to the chart 

NumericalAxis secondaryAxis = new NumericalAxis();

secondaryAxis.Header = "Height(in cm)";          

chart.SecondaryAxis = secondaryAxis;


//Initialize the two series for SfChart
ColumnSeries series = new ColumnSeries();

series.ItemsSource = (new ViewModel()).Data;
series.XBindingPath = "Name";            
series.YBindingPath = "Height";         
            
//Adding Series to the Chart Series Collection
chart.Series.Add(series);

VB.NET

Dim chart As New SfChart()

'Adding horizontal axis to the chart 

Dim primaryAxis As New CategoryAxis()

primaryAxis.Header = "Name"
chart.PrimaryAxis = primaryAxis


'Adding vertical axis to the chart  

Dim secondaryAxis As New NumericalAxis()

secondaryAxis.Header = "Height(in cm)"

chart.SecondaryAxis = secondaryAxis        

'Initialize the two series for SfChart
Dim series As New ColumnSeries()

series.ItemsSource = New ViewModel().Demands
series.XBindingPath = "Name"
series.YBindingPath = "Height"
        
'Adding Series to the Chart Series Collection

chart.Series.Add(series)

NOTE

Syncfusion® Chart also supports rendering combination of multiple series. Refer this for details.

Add Title

The header of the chart acts as the title, to provide quick information to the user about the data being plotted in the chart. You can set title using Header property of chart as shown below.

XAML

<Grid> 

   <syncfusion:SfChart Header="Chart" > 

   </syncfusion:SfChart> 

</Grid>

C#

 

chart.Header = "Chart";

VB.NET

chart.Header = "Chart"

Enable data labels

You can add data labels to improve the readability of the chart and it can be enabled using AdornmentsInfo property of ChartSeries. By default, there is no label displayed, you have to set ShowLabel property of ChartAdornmentInfo as True.

XAML

<syncfusion:SfChart>

	...

  <syncfusion:ColumnSeries > 
     <syncfusion:ColumnSeries.AdornmentsInfo>
          <syncfusion:ChartAdornmentInfo ShowLabel="True"/> 
     </syncfusion:ColumnSeries.AdornmentsInfo> 
  </syncfusion:ColumnSeries>     

	...

</syncfusion:SfChart>

C#

 

series.AdornmentsInfo = new ChartAdornmentInfo (){ ShowLabel = true };

VB.NET

 

series.AdornmentsInfo = New ChartAdornmentInfo() With {.ShowLabel = True}

Refer this link to learn more about the options available in SfChart to customize chart adornments.

Enable legend

You can enable legend using SfChart.Legend property as shown below,

XAML

<syncfusion:SfChart>

	...

    <syncfusion:SfChart.Legend>

        <syncfusion:ChartLegend/>

    </syncfusion:SfChart.Legend>

    ...

</syncfusion:SfChart>

C#

 

chart.Legend = new ChartLegend ();

VB.NET

 

chart.Legend = New ChartLegend ()

Additionally, you need to set label for each series using Label property of ChartSeries, which will be displayed in corresponding legend.

XAML

<syncfusion:SfChart>

	...

      <syncfusion:ColumnSeries Label="Heights" ItemsSource="{Binding Data}" XBindingPath="Name" YBindingPath="Height" />

	...

</syncfusion:SfChart>

C#

 

ColumnSeries series = new ColumnSeries (); 
series.ItemsSource = (new ViewModel()).Data;
series.XBindingPath = "Name"; 
series.YBindingPath = "Height"; 
series.Label = "Heights";

VB.NET

 

Dim series As New ColumnSeries () 
series.ItemsSource = New ViewModel().Data
series.XBindingPath = "Name" 
series.YBindingPath = "Height" 
series.Label = "Heights"

Refer this link to learn more about the options available in SfChart to customize legend.

Enable tooltip

Tooltips are used to show information about the segment, when you click on the segment. You can enable tooltip by setting series ShowTooltip property to true.

XAML

<syncfusion:SfChart>

	...

   <syncfusion:ColumnSeries ShowTooltip="True" ItemsSource="{Binding Data}" XBindingPath="Name" YBindingPath="Height"/>

	...

</syncfusion:SfChart>

C#

 

ColumnSeries series = new ColumnSeries();
series.ItemsSource = (new ViewModel()).Data;
series.XBindingPath = "Name";          
series.YBindingPath = "Height";
series.ShowTooltip = true;

VB.NET

 

Dim series As New ColumnSeries () 
series.ItemsSource = New ViewModel().Data
series.XBindingPath = "Name" 
series.YBindingPath = "Height" 
series.ShowTooltip = True

Refer this link to learn more about the options available in SfChart to customize tooltip.
