Hello Dominic,

In order to achieve this, you can subscribe to the LabelFormatting event and in the handler manually move the label to the left. This can be done by setting a proper value to the PointLabelElement.PosittionOffset property. Please refer to the following example that uses LineSeries to plot the data points:

 public RadForm1()
 {
     InitializeComponent();

     LineSeries lineSeries = new LineSeries();
     lineSeries.DataPoints.Add(new CategoricalDataPoint(21, "Jan"));
     lineSeries.DataPoints.Add(new CategoricalDataPoint(22, "Apr"));
     lineSeries.DataPoints.Add(new CategoricalDataPoint(12, "Jul"));
     lineSeries.DataPoints.Add(new CategoricalDataPoint(15, "Oct"));
     this.radChartView1.Series.Add(lineSeries);
     LineSeries lineSeries2 = new LineSeries();
     lineSeries2.DataPoints.Add(new CategoricalDataPoint(18, "Feb"));
     lineSeries2.DataPoints.Add(new CategoricalDataPoint(15, "Apr"));
     lineSeries2.DataPoints.Add(new CategoricalDataPoint(17, "Jul"));
     lineSeries2.DataPoints.Add(new CategoricalDataPoint(22, "Oct"));
     lineSeries2.DataPoints.Add(new CategoricalDataPoint(30, "Nov"));
     this.radChartView1.Series.Add(lineSeries2);
     lineSeries.ShowLabels = true;
     lineSeries2.ShowLabels = true;

     this.radChartView1.LabelFormatting += this.RadChartView1_LabelFormatting;
 }

 private void RadChartView1_LabelFormatting(object sender, ChartViewLabelFormattingEventArgs e)
 {
     PointLabelElement pointLabel = e.LabelElement as PointLabelElement;
     if (pointLabel != null)
     {
         pointLabel.PositionOffset = new PointF(-10, 0);
         pointLabel.DataPointElement.PointSize = new SizeF(10, 10);
     }
 }

I hope this helps. Should you have other questions do not hesitate to ask.
