Gap Length
The CategoricalAxis and the DateTime axes (DateTimeCategoricalAxis and DateTimeContinuousAxis) expose a GapLength property which can be used to define what type of fraction of the category slot will be filled with the visual representation of the data point. This property expects a relative value between 0 and 1. For the purpose of this tutorial we will use BarSeries as the gap length can be easily observed.
Example 1 demonstrates that setting the GapLength to 0.90 value tells the gap to take 90% of the available space in the category slot. The other 10% will be taken by the bar visuals of the series.
Example 1: Setting the GapLength property
<telerik:RadCartesianChart Palette="Windows8">
<telerik:RadCartesianChart.HorizontalAxis>
<telerik:CategoricalAxis GapLength="0.90"/>
</telerik:RadCartesianChart.HorizontalAxis>
<telerik:RadCartesianChart.VerticalAxis>
<telerik:LinearAxis />
</telerik:RadCartesianChart.VerticalAxis>
<telerik:RadCartesianChart.Series>
<telerik:BarSeries>
<telerik:BarSeries.DataPoints>
<telerik:CategoricalDataPoint Category="January" Value="2" />
