+##### Auto Tick Angle Options
+
+*New in 5.18*
+
+If `tickangle` is not explicitly set, its default value is `auto`, meaning if the label needs to be rotated to avoid labels overlapping, it will rotate by either 30 or 90 degrees. Using `autotickangles`, you can also specify a list of angles for `tickangle` to use. If `tickangle` is `auto` and you provide a list of angles to `autotickangles`, the label angle will be set to the first value in the list that prevents overlap. 
+
+```python
+import plotly.express as px
+df = px.data.gapminder()
+df = df.loc[(df.continent=="Asia") & (df.year==1992)]
+fig = px.histogram(df, x=df.country, y=df.gdpPercap)
+
+fig.update_xaxes(autotickangles=[45, 60, 90])
+
+fig.show()
+```

 #### Enumerated Ticks with Tickvals and Ticktext
 
 The `tickvals` and `ticktext` axis properties can be used together to display custom tick label text at custom locations along an axis. They should be set to lists of the same length where the `tickvals` list contains positions along the axis, and `ticktext` contains the strings that should be displayed at the corresponding positions.
