How to "shake loose" an auto scaling graph when it doesn't autoscale?

Scenario: I load some data, a time series, into a uiaxes component. Everything looks beautiful:

My user then chooses a shorter portion of that series to work on. I redisplay the shorter data in the same uiaxes, and it doesn't resize:

Question: how to "shake it loose" and cause it to redo the auto scaling? I don't want to explicitly set the bounds of the graph if I don't have to, because then it is no longer auto scaling at all, and that's a pain. Is there a way to do this?

Where ax is your uiaxes component:

xlim(ax,'auto')
ylim(ax,'auto')

or, equivalently:

ax.XLimMode = 'auto';
ax.YLimMode = 'auto';
