How to label aach item on an axis in a WPF Syncfusion Chart

[David Schmidt]

I am getting a variable number of labels on my x-axis when trying to show a chart. I want a label for each item on the x-axis. I have uploaded a zip file with a picture of the result I'm seeing. Can anyone help me?

My data source is an ObservableCollection<Agent> and I'm trying to plot Agent.FullName (x-axis) by Agent.UnitsSold (y-axis).

public class Agent : INotifyPropertyChanged
    {
        private string m_lastName;
        private string m_firstName;
        private int m_unitsSold;

        public event PropertyChangedEventHandler PropertyChanged;

        public Agent()
        {
            FirstName = string.Empty;
            LastName = string.Empty;
            UnitsSold = 0;

        }

        public string LastName
        {
            get { return m_lastName; }
            set { m_lastName = value; FirePropertyChanged("LastName"); }
        }

        public string FirstName
        {
            get { return m_firstName; }
            set { m_firstName = value; FirePropertyChanged("FirstName"); }
        }

        public string FullName
        { get { return FirstName + " " + LastName; } }

        public int UnitsSold
        {
            get { return m_unitsSold; }
            set { m_unitsSold = value; FirePropertyChanged("UnitsSold"); }
        }

        private void FirePropertyChanged(string propertyName)
        {
            PropertyChangedEventHandler temp = PropertyChanged;
            if (temp != null)
                temp(this, new PropertyChangedEventArgs(propertyName));
        }
    }

<syncfusion:Chart Name="Chart1"  Margin="0" Background="White">
            <syncfusion:Chart.Header>
                <TextBlock FontSize="20" TextWrapping="Wrap" FontWeight="Regular">Agents- Units Sold</TextBlock>
            </syncfusion:Chart.Header>
            <!--Chart area to present chart segments-->
            <syncfusion:ChartArea IsContextMenuEnabled="False" ContextMenu="{x:Null}" >
                <syncfusion:ChartArea.ColorModel>
                    <syncfusion:ChartStyleModel Palette="Metro"/>
                </syncfusion:ChartArea.ColorModel>
                <!--Chart area Legend declaration-->
                <syncfusion:ChartArea.Legend>
                    <syncfusion:ChartLegend Name="Legend1"  syncfusion:Chart.Dock="{Binding ElementName=Position1, Path=SelectedItem, Mode=TwoWay}"></syncfusion:ChartLegend>
                </syncfusion:ChartArea.Legend>
                <syncfusion:ChartArea.PrimaryAxis>
                    <syncfusion:ChartAxis Header="Agents" RangePadding="Normal"  HidePartialLabel="False"  LabelRotateAngle="90" EdgeLabelsDrawingMode="Shift"></syncfusion:ChartAxis>
                </syncfusion:ChartArea.PrimaryAxis>

                <syncfusion:ChartArea.SecondaryAxis>
                    <syncfusion:ChartAxis Header="Units Sold" EdgeLabelsDrawingMode="Shift"></syncfusion:ChartAxis>
                </syncfusion:ChartArea.SecondaryAxis>
                <!--Chart series declaration-->
                <syncfusion:ChartSeries Name="SeriesA" Type="Column" IsIndexed="True" Unit="Units"  DataSource="{Binding Agents}" BindingPathX="FullName" BindingPathsY="UnitsSold" Label="Office" StrokeThickness="0.5" >

                </syncfusion:ChartSeries>
            </syncfusion:ChartArea>
        </syncfusion:Chart>

Hi David,

Thanks for contacting Syncfusion support.

You can achieve the requirement by setting the Interval as 1 in ChartAxis(PrimaryAxis) as in the following code example.

[XAML]

              <syncfusion:ChartArea.PrimaryAxis>

                    <syncfusion:ChartAxis Header="Agents" RangePadding="Normal"  HidePartialLabel="False"  Interval="1"

                                          LabelRotateAngle="90" EdgeLabelsDrawingMode="Shift"></syncfusion:ChartAxis>

                </syncfusion:ChartArea.PrimaryAxis>

Please refer the following UG documentation link to know about ChartAxis
