I want to chart several different quantities vs. time, allowing at-a-glance
observation of correlated trends. Putting all the data series in one chart
will look far too busy (not to mention the variations in scale). Instead, I
want to display several charts, stacked one above the next. The x-axes would
all be identical, but each y-axis would be scaled according the range of
values. How can I do it in Excel?
