-### Zooming subplots to the same range
+### Synchronizing axes in subplots with `matches`
 
-Using `facet_col` from `plotly.express` let zoom each facet to the same range implicitly. However, if the subplots are created with `make_subplots`, the axis needs to be updated with `matches` parameter to zoom all the subplots accordingly. Zoom in one trace below, to see the other subplots zoomed to the same x-axis range:
