 #### Configure Surface Contour Levels
 This example shows how to slice the surface graph on the desired position for each of x, y and z axis. [contours.x.start](https://plot.ly/python/reference/#surface-contours-x-start) sets the starting contour level value, `end` sets the end of it, and `size` sets the step between each contour level.

 ```python
 import plotly.graph_objects as go

 fig = go.Figure(go.Surface(
    contours = {
        "x": {"show": True, "start": 1.5, "end": 2, "size": 0.04, "color":"white"},
        "z": {"show": True, "start": 0.5, "end": 0.8, "size": 0.05}
    },
    x = [1,2,3,4,5],
    y = [1,2,3,4,5],
    z = [
        [0, 1, 0, 1, 0],
        [1, 0, 1, 0, 1],
        [0, 1, 0, 1, 0],
        [1, 0, 1, 0, 1],
        [0, 1, 0, 1, 0]
    ]))
 fig.update_layout(
        scene = {
            "xaxis": {"nticks": 20},
            "zaxis": {"nticks": 4},
            'camera_eye': {"x": 0, "y": -1, "z": 0.5},
            "aspectratio": {"x": 1, "y": 1, "z": 0.2}
        })
