+#### Gradient Fill
+
+*New in 5.20*
+
+Scatter traces with a fill support a `fillgradient`, which is a `dict` of options that defines the gradient. Use `fillgradient.colorscale` to define the [colorscale](https://plotly.com/python/colorscales) for the gradient and choose a `type` to define the orientation of the gradient (`'horizontal'`, `'vertical'` or `'radial'`). 
+
+In the following example, we've defined a `horizontal` `fillgradient` with a colorscale of three colors. 
+
+```python
+import plotly.graph_objects as go
+
+fig = go.Figure(
+    [
+        go.Scatter(
+            x=[1, 2, 3, 4],

 #### Stacked Area Chart
 
 The `stackgroup` parameter is used to add the `y` values of the different traces in the same group. Traces in the same group fill up to the next trace of the group.
