Thanks for the reply.

Unfortunatelly it is already set to 'Far'. 

 I've also tried to set the <Margin> for Axis to a different value but this is not working as well. 

Maybe there is some Property to set the Margin for the whole Chart?

P.S. Oh... and I've forgot to mention that this happens only when the 'Orientation' is set to Custom, when it's set to: 'VerticalLeftFacing' it's working fine. It looks like control can't calculate the size or location for the label.

You can try changing axis.Labels.Layout.Behavior to None. Maybe try setting the Padding property under the Layout property. Otherwise, it's pretty hard to guess without seeing a code snippet.
What version did you upgrade to? Can you paste the code you used for the X2 axis?

 Please find the attached code below:

"*.aspx.cs" file: 

 private void m_chart_8_LoadData()
        {

...

  m_chart_8.Axis.X2.Labels.Font = new System.Drawing.Font("Microsoft Sans Serif", 10F, (System.Drawing.FontStyle.Regular | System.Drawing.FontStyle.Bold), System.Drawing.GraphicsUnit.Point);
            m_chart_8.Axis.X2.Labels.SeriesLabels.Font = new System.Drawing.Font("Microsoft Sans Serif", 7.8F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point);
            m_chart_8.AxisX2SeriesLabelsFormat = "SeriesLabel";
            m_chart_8.AxisX2PaintElementImage = "";

...

Hope this will help you to understand the problem. 

Many thanks for your help. 

This is a bug, and it's already fixed. The fix will be included in the next available hotfix. Until this you could try using:

this.UltraChart1.Axis.X2.Labels.Layout.Padding = -10;

 Many thanks for your help.

This works fine for now and after applying the Hot Fix I'll get back to previous version. 

Kindest regards,
