How can I get all my 25 titles to show on the timeline? As you can see from below screenshot only 3 titles are shown. I need all 25 titles represented by each dot to show. How can I accomplish this?

Here is my code:

<igtl:XamTimeline x:Name="xamTimeline" Width="900" Height="250" Title="Milestone" >

                    <igtl:XamTimeline.Axis>

                        <igtl:NumericTimeAxis Minimum="1" Maximum="27" AutoRange="True" ShowLabels="True" Unit="1" />

                    </igtl:XamTimeline.Axis>

                    <igtl:XamTimeline.PreviewAxis>

                        <igtl:PreviewAxis ShowLabels="True" />

                    </igtl:XamTimeline.PreviewAxis>                   

</igtl:XamTimeline>

       Code behind:

milestoneClubs = DataUtil.MilesotneClubs;

            // xamTimeline data binding

            NumericTimeSeries series = new NumericTimeSeries();

            series.DataSource = milestoneClubs;

            // data mapping

            series.DataMapping = "Time=ID;Title=Note;Details=Note;";       

            this.xamTimeline.Series.Add(series);
