Rendering within function cross and IsLabelsInside is wrong

I want to get a graph having the X-Axis at the top of the graph rectangle and having the X-Axis texts above the X-Axis. I am nearly finished with the following code

[code]
myPane = MTA_Graph.GraphPane;
// Set the titles and axis labels
myPane.Title.Text = "My Test Date Graph";
myPane.XAxis.Title.Text = "Analysezeitpunkt";
myPane.YAxis.Title.Text = "Meilenstein Termine";

myPane.Chart.Border.IsVisible = false;

PointPairList list = new PointPairList();
for (int i = 0; i < 36; i++)
{
double x = (double)new XDate(2011, 5, i + 11);
double y = (double)new XDate(2011, 5, i + 13);
list.Add(x, y);
}

LineItem myCurve = myPane.AddCurve("Milestone1", list, Color.Red, SymbolType.Diamond);

// Set the XAxis to date type
myPane.XAxis.Type = AxisType.Date;
myPane.XAxis.Scale.Format = "yyyy-MM";
myPane.XAxis.Scale.Min = (double)new XDate(2011, 1, 1);
myPane.XAxis.Scale.Max = (double)new XDate(2012, 1, 1);
myPane.XAxis.Scale.MajorUnit = DateUnit.Month;
myPane.XAxis.Scale.MajorStep = 1.0;
myPane.XAxis.Scale.MinorUnit = DateUnit.Month;
myPane.XAxis.Scale.MinorStep = 0.25;
myPane.XAxis.Scale.FontSpec.Angle = 90;
myPane.XAxis.Scale.IsLabelsInside = true;
myPane.XAxis.Cross = (double)new XDate(2012, 1, 1);
myPane.XAxis.Title.IsTitleAtCross = false;
myPane.XAxis.MajorGrid.IsVisible = true;
myPane.XAxis.MajorTic.IsOpposite = false;
myPane.XAxis.MinorTic.IsOpposite = false;
// Y-Achsen Definition
myPane.YAxis.Type = AxisType.Date;
myPane.YAxis.Scale.Format = "yyyy-MM";
myPane.YAxis.Scale.Min = (double)new XDate(2011, 1, 1);
myPane.YAxis.Scale.Max = (double)new XDate(2012, 1, 1);
myPane.YAxis.Scale.MajorUnit = DateUnit.Month;
myPane.YAxis.Scale.MajorStep = 1.0;
myPane.YAxis.MajorGrid.IsVisible = true;
myPane.YAxis.Scale.MinorUnit = DateUnit.Month;
myPane.YAxis.Scale.MinorStep = 0.25;
myPane.YAxis.MajorTic.IsOpposite = false;
myPane.YAxis.MinorTic.IsOpposite = false;
myPane.Legend.Position = LegendPos.BottomCenter;

// Calculate the Axis Scale Ranges
MTA_Graph.AxisChange();
[/code]

The problem i get with this code is that my X-Axis Value texts are not shown completely and are plotted over the title of the chart. The text need more space outside the control.
See the attached screenshot.
