I have been trying to figure out how to add general text labels to a graph.
I have seen some references on adding a label tied to a value on a axis, but
what I need is a general label below the x axis that is not tied to a value like 
the link below, How do I do that?

Chart Lables

Hi Devin,
The following sample shows how to add a scale title and header and footer labels:
nChartControl1.Panels.Clear();

NLabel header = new NLabel("Some Header Text");
header.DockMode = PanelDockMode.Top;
nChartControl1.Panels.Add(header);

NLabel footer = new NLabel("Some Footer Text");
footer.DockMode = PanelDockMode.Bottom;
nChartControl1.Panels.Add(footer);

NCartesianChart chart = new NCartesianChart();
chart.DockMode = PanelDockMode.Fill;
nChartControl1.Panels.Add(chart);

chart.Axis(StandardAxis.PrimaryY).ScaleConfigurator.Title.Text = "Y Axis Title";
chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator.Title.Text = "X Axis Title";

NBarSeries bar = new NBarSeries();

bar.Values.Add(10);
bar.Values.Add(20);
bar.Values.Add(30);

chart.Series.Add(bar);
You can also take a look at the Panels \ Labels examples that show how to apply XML formatting to labels.
Let us know if you meet any problems or have any questions.
