I'm trying to create a marked zone that goes between two points in a step line series, but instead the zone runs from the centre of one category to the next.

Is it at all possible to offset the zone or otherwise transform my data for the chart so that I can get the effect I'm going for? I've attached a quick screenshot showing the actual area in grey and where I would want it as a red outline.

Hello Phillip, 

Thank you for writing.

The actual position of the data points with respect to the horizontal axis can be controlled with the PlotMode property of the axis: You can try setting it to BetweenTicks and check if the result would fit better your local setup. I have tested a similar set up on my end as well: 
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
    public RadForm1()
        SteplineSeries lineSeries = new SteplineSeries();
        lineSeries.PointSize = new SizeF(10,10);
        lineSeries.DataPoints.Add(new CategoricalDataPoint(20, "Jan"));
        lineSeries.DataPoints.Add(new CategoricalDataPoint(22, "Apr"));
        lineSeries.DataPoints.Add(new CategoricalDataPoint(12, "Jul"));
        lineSeries.DataPoints.Add(new CategoricalDataPoint(19, "Oct"));
        CategoricalAxis axis = this.radChartView1.Axes[0] as CategoricalAxis;
        axis.PlotMode = AxisPlotMode.BetweenTicks;
        CartesianPlotBandAnnotation annotation1 = new CartesianPlotBandAnnotation();
        annotation1.Axis = this.radChartView1.Axes[0] as CartesianAxis;
        annotation1.From = "Apr";
        annotation1.To = "Jul";
        annotation1.BackColor = Color.FromArgb(100, Color.LightBlue);
        annotation1.BorderColor = Color.Black;
        annotation1.BorderWidth = 1;

I am also attaching a screenshot showing the result. Let me know if you need further assistance.
