Description sandra pazos 2013-11-06 08:55:20 EST 
When you work with editor in design-time and you add a new AxesBreaksTool with its breaks, appears a NullReferenceException in the AxisBreak class. I have made many test and I think the problem is caused by the order that Editor added the default  properties and the new AxisBreak tool is created to assign an existent Axisbreak tool in the code. 
To reproduce the problem exactly, see next piece of code:

Code is added for AxisBreak editor:

 // axisBreaksTool1
      //
      this.axisBreaksTool1.Axis = this.tChart1.Axes.Bottom;
      axisBreak1.EndValue = 0D;
      axisBreak1.StartValue = 0D;
      new Steema.TeeChart.Tools.AxisBreaks().Add(axisBreak1);
      //


Previous code causes the NullReferenceException.

On the other hand, I have made modifications in the code and the NullReferenceExeception disappears: 

      this.axisBreaksTool1.Axis = this.tChart1.Axes.Bottom;
      this.axisBreaksTool1.Breaks.Add(axisBreak1);
      axisBreak1.EndValue = 0D;
      axisBreak1.StartValue = 0D;

My opinion is that the Editor should assign the break to the existing AxisBreakTool and respects the order tools is created and assigned.

Editor problem, not tool problem.
