You can set the milliseconds label format for axis labels and trackball axis labels by using LabelFormat property of LabelStyle and TrackballLabelStyle in ChartAxis. The following code illustrates how to set the milliseconds label format for axis and trackball axis labels.

XAML:

<chart:SfChart.PrimaryAxis>
    <chart:DateTimeAxis ShowTrackballInfo="True">
        <chart:DateTimeAxis.LabelStyle>
        <chart:ChartAxisLabelStyle LabelFormat="MM/dd/yyyy (HH:mm:ss.fff)" />
        </chart:DateTimeAxis.LabelStyle>
        <chart:DateTimeAxis.TrackballLabelStyle>
            <chart:ChartTrackballAxisLabelStyle LabelFormat="MM/dd/yyyy (HH:mm:ss.fff)"/>
        </chart:DateTimeAxis.TrackballLabelStyle>
    </chart:DateTimeAxis>
</chart:SfChart.PrimaryAxis>
. . .
 
<chart:SfChart.ChartBehaviors>
    <chart:ChartTrackballBehavior />
</chart:SfChart.ChartBehaviors>

C#:

DateTimeAxis dateTimeAxis = new DateTimeAxis();
dateTimeAxis.ShowTrackballInfo = true;
dateTimeAxis.LabelStyle.LabelFormat = "MM/dd/yyyy (HH:mm:ss.fff)";
dateTimeAxis.TrackballLabelStyle.LabelFormat = "MM/dd/yyyy (HH:mm:ss.fff)";
chart.PrimaryAxis = dateTimeAxis;
