Excel chart question

I have a column chart with 0-400 on the Y axis, and only two or three columns out of about fifteen that go to around 400, with the rest staying down below ten. I want to put those little squiggle breaks in the long columns and on the Y-Axis that tell people that the column is a lot longer than shown, but has been shortened for convenience sake and to show up the shorter columns.
Does anyone know how to do that?

Thanks

 

Not exactly sure what you are getting at, but if you want to add a comment bubble, just right click on any blank part of the Excel spreadsheet and "Insert Comments" is an option.

Re-reading your query, I think I know what you mean, you want to break the column with a break that looks like a lightning bolt. Can't help you with that, but someone reading this will, hopefully, provide the solution. I am interested myself, in the answer. Bazza

Here's how it's done, but what a lot to go through...

Thanks MrPewty for the link. Bl**dy hell, you are right.
I've copied the expanation as a reference.
Hope to hell I never have to use it, though.
How did you find it? Google search, or what? Bazza
