# Chart Data Labels
# Chart Data Labels in PowerPoint

Data Labels on a chart make it easier to understand. They show important information about the lines or points on the chart. Using Presentation, you can **customize the data labels in the chart**.

## Show Leader lines

The leader lines can be shown in a chart through [ShowLeaderLines](https://help.syncfusion.com/cr/file-formats/Syncfusion.XlsIO.Implementation.Charts.ChartDataLabelsImpl.html#Syncfusion_XlsIO_Implementation_Charts_ChartDataLabelsImpl_ShowLeaderLines) API which can be set to all data labels by enabling the leader lines for [DefaultDataPoint](https://help.syncfusion.com/cr/file-formats/Syncfusion.XlsIO.Implementation.Charts.ChartDataPointsCollection.html#Syncfusion_XlsIO_Implementation_Charts_ChartDataPointsCollection_DefaultDataPoint).

The following code illustrates how to enable the leader lines for all data labels in the chart.

{% tabs %}
{% highlight c# tabtitle="C# [Cross-platform]" %}

// Enable the leader lines in Chart.
chart.Series[0].DataPoints.DefaultDataPoint.DataLabels.ShowLeaderLines = true;

{% endhighlight %}
{% highlight c# tabtitle="C# [Windows-specific]" %}

// Enable the leader lines in Chart.
chart.Series[0].DataPoints.DefaultDataPoint.DataLabels.ShowLeaderLines = true;

{% endhighlight %}
{% highlight vb.net tabtitle="VB.NET [Windows-specific]" %}

' Enable the leader lines in Chart.
chart.Series[0].DataPoints.DefaultDataPoint.DataLabels.ShowLeaderLines = true;

{% endhighlight %}
{% endtabs %}
