+#### Setting only a Lower or Upper Bound for Range
+
+*New in 5.16*
+
+You can also set just a lower or upper bound manually and have autorange applied to the other bound by setting it to `None`. In the following example, we set a an upper bound of 4.5 on the x axes, while specifying `None` for the lower bound, meaning it will use autorange. On the y axes, we set the lower bound, and use `None` for the upper bound, meaning that uses autorange.

+When setting a range manually, you can also set a `maxallowed` or `minallowed` for an axis. With this set, you won't be able to pan further than the min or max allowed. In this example, we've set the minimum allowed on the x-axis to 1 and the maximum allowed on the y-axis to 10.

-### Fixed Ratio Axes with Compressed domain

-If an axis needs to be compressed (either due to its own `scaleanchor` and `scaleratio` or those of the other axis), `constrain` determines how that happens: by increasing the "range" (default), or by decreasing the "domain".

 ### Axis range for log axis type
 
 If you are using a `log` type of axis and you want to set the range of the axis, you have to give the `log10` value of the bounds when using `fig.update_xaxes` or `fig.update_layout`. However, with `plotly.express` functions you pass directly the values of the range bounds (`plotly.express` then computes the appropriate values to pass to the figure layout).

+
+#### Autorange Options
+
+*New in 5.16*
+
+You can further configure how autorange is applied using `autorangeoptions` to specify maximum or minimum values or values to include.
+
+##### Specifying Minimum and Maximum Allowed Values
+
+Using `autorangeoptions.maxallowed`, you can specify an exact value to use as the autorange maximum. With `autorangeoptions.minallowed`, you can specify an exact value to use as the autorange minimum.
+
+```python
+import plotly.express as px
+
+df = px.data.iris()
+
+fig = px.scatter(df, x="sepal_width", y="sepal_length")
+fig.update_yaxes(autorangeoptions=dict(minallowed=3))
+fig.update_xaxes(autorangeoptions=dict(maxallowed=5))
+
+fig.show()
+```
+
+##### Clip Minimum and Maximum 
+
+You can also clip an axis range at a specific maximum or minimum value with `autorangeoptions.clipmax` and `autorangeoptions.clipmin`.
+
+```python
+import plotly.express as px
+
+df = px.data.iris()
+
+fig = px.scatter(df, x="sepal_width", y="sepal_length")
+fig.update_yaxes(autorangeoptions=dict(clipmin=5))
+fig.update_xaxes(autorangeoptions=dict(clipmax=4))
+
+fig.show()
+```
+
+##### Specify Values to be Included
+
+Use `autorangeoptions.include` to specify a value that should always be included within the calculated autorange. In this example, we specify that for the autorange calculated on the x-axis, 5 should be included. 
+
+```python
+import plotly.express as px
+
+df = px.data.iris()
+
+fig = px.scatter(df, x="sepal_width", y="sepal_length")
+fig.update_xaxes(autorangeoptions=dict(include=5))
