The deal is that the graphs and charts try not to be CPU hogs when
hidden. That means that they don't autoscale, they don't draw, they
don't do much of anything. This is true for the autoscale always as
well as the autoscale once. Perhaps it should be changed of the once
case, but at the moment it looks the same to the graph. Anyway, one
option is to figure out what you want the scales set to and just set the
scale range values. Sometimes this is trivial, like on X scales. If it
isn't trivial, and you are already using a state machine, have the
button store its press in some state info so that when a hidden chart is
being shown, it does the autoscale then.
This means that the visible
charts will do the autoscales, and if the user never looks at the other
charts, no work was done.
If you would like to see the autoscale once changed, consider filing a
bug report.
