This may be a FAQ, but I cannot find/figure it out.

I have several series of data, which I am stacking up
on top of each other in a column chart, for different
X-axis categories.

The first series numbers are very large, the later ones
become mostly increasingly small.

I would like to focus the chart on the top end, and not
extend it all the way to the x-axis, as thus the very large
series-one columns would take up most of the chart,

Now, I know I can set the 'minimum' on the y-axis to
some value (and thus 'lose' most of the series-1
stacks in the graph), but that would mean that visually
there is no real indication that the chart has been 'cut-off'.

Is there any way I can display some 'rip effect' like thus:

120-| |---| |---|
110-| |---| |@@@| |:::|
100-| |:::| |---| |:::|
90-| |:::| |:::| |:::|
/\/\/\/\/\/\/\/\/\/\/\/\/
/\/\/\/\/\/\/\/\/\/\/\/\/
10-| |:::| |:::| |:::|
0-+---------------------
1 2 3

which would visually indicate that there is a whole lot of
y-axis missing?

Any help how to accomplish this would be welcome.
So would be hints as to better describe this feature
(are there terms for this), so I can google more effectively?

PS: is there a charting FAQ for Excel?
