To anyone interested, Ive adapted this function to work on any axis: We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here. In fact, that list may contain any valid tight_layout This has two advantages: the code you write will be more portable, and Matplotlib events are aware of things like data coordinate space and which axes the WebNow we'll generate a figure with two axes, one on top of the other. # gs2.tight_layout cannot handle the subplots from the first gridspec, # (gs1), so it will raise a warning. Here is a simple example using this function: Autoscaling always uses the full range of the data, so the y-axis is scaled by full extent of the y-data, not just what's within the x-limits.
