+### Setting the Surface Color
+
+You can use the `surfacecolor` attribute to define the color of the surface of your figure. In this example, the surface color is drawn relation to the x-axis data. 
+
+```python
+import plotly.graph_objects as go
+import numpy as np
+x, y = 4 * np.pi * np.mgrid[0:1:20j, 0:1:20j]
+z = np.sin(x)
+fig = go.Figure(go.Surface(x=x, y=y, z=z, surfacecolor=x))

+### Bar Charts With Multicategory Axis Type
+
+If your traces have arrays for `x` or `y`, then the axis type is automatically inferred to be `multicategory`.

+x = [
+    ["BB+", "BB+", "BB+", "BB", "BB", "BB"],
+    [16, 17, 18, 16, 17, 18,]

 ### Line Plot with go.Scatter
 
 If Plotly Express does not provide a good starting point, it is possible to use the more generic `go.Scatter` function from `plotly.graph_objects`. Whereas `plotly.express` has two functions `scatter` and `line`, `go.Scatter` can be used both for plotting points (makers) or lines, depending on the value of `mode`. The different options of `go.Scatter` are documented in its [reference page](https://plotly.com/python/reference/#scatter).
