Hi Jeremy,

Are you sure the x axis not visible? We tested with the following code and everything was working Ok (there is not overdraw from the chart back wall on the series):

   NChart chart = nChartControl1.Charts[0];

   NStepLineSeries stepLine = new NStepLineSeries();

   stepLine.BorderStyle.Color = Color.Red;
   stepLine.DataLabelStyle.Visible = false;

   for (int i = 0; i < 10; i++)
   {
    stepLine.Values.Add(i % 2);
   }

   chart.Series.Add(stepLine);

   chart.Axis(StandardAxis.PrimaryX).Visible = false;

Hi Jeremy,

Please submit an application that replicates the problem for further review. We tested with the following code and were not able to replicate this problem:

   NChart chart = nChartControl1.Charts[0];

   chart.Axis(StandardAxis.PrimaryX).Visible = false;

   NStepLineSeries stepline = new NStepLineSeries();
   chart.Series.Add(stepline);

   stepline.Values.Add(10);
   stepline.Values.Add(20);
   stepline.Values.Add(30);
   stepline.Values.Add(10);
   stepline.BorderStyle.Color = Color.Orange;

   chart.Wall(ChartWallType.Back).VisibilityMode = WallVisibilityMode.Hidden;

   nChartControl1.BackgroundStyle.FillStyle = new NColorFillStyle(Color.Black);

Hi Jeremy,

When the axis uses paging it will also automatically apply clip to the plot area - it looks that in this case the pixels covered by the step line are also clipped. To work around this you can consider to extend the y axis area using a view range inflate - check out the following example:

All Examples\Axes\General\View Range Inflate

You need to apply an absolute inflate to the axis - for example one or two point inflate should do the job...
