 In the following example we create a `SphericalDetector` with two axes: an x-axis with variable bin size and a y-axis with fixed bin size. The code and resulting detector plane are shown below.
 
 ```python
-nxbins = 13
-xedges = [-1.0*deg, -0.7*deg, -0.5*deg, -0.3*deg, -0.2*deg, -0.1*deg, -0.025*deg, 0.025*deg, 0.1*deg, 0.2*deg, 0.3*deg, 0.5*deg, 0.7*deg, 1.0*deg]
-xaxis = GenericScale("my-x-axis", nxbins, xedges)
+xedges = [-1.0*deg, -0.7*deg, -0.7*deg, -0.5*deg, -0.5*deg, -0.3*deg, -0.3*deg, -0.2*deg, -0.2*deg, -0.1*deg, -0.1*deg, -0.025*deg, -0.025*deg, 0.025*deg, 0.025*deg, 0.1*deg, 0.1*deg, 0.2*deg, 0.2*deg, 0.3*deg, 0.3*deg, 0.5*deg, 0.5*deg, 0.7*deg, 0.7*deg, 1.0*deg]
+xaxis = GenericScale("my-x-axis", xedges)
  
 yaxis = EquiDivision("my-y-axis", 10, 0.0, 10.)
