There is currently no direct way to color surfaces by coordinate
value. You can, however, add a Calculator after the Transform filter
and simply set the expression to coordsY - no recomputation of the
normalization is needed. This will copy your normalized Y coordinate
values to a new array named "Result", and you can then color the
isosurface by "Result". "Result" is just the default name - you can
change it however you wish.

Click the Edit button next to the Axes Grid option. Click the gear
icon in the top right of the dialog that appears. Under Face
Properties, click on the "Faces to Render" combo box. Turn off the
sides you do not wish to see by selecting them in the combo box.

In the same dialog described above, check the "X Axis Use Custom
Labels", and you can specify exactly the labels you want. There is no
property to directly change the increment.

Best,
Cory
