Hello Excel Friends,

I wanted to do a Strategic Group mapping but I have a couple of problems because I have no fucking how excel works or at least
whatever I tried to do, does not work.

I basically have one x variable let's call it breadth of portfolio but it is a number like 10/ or 15.
The scond one is a less complicated and it comes down to one value as well: y, is the price of a product.

The third value, however, should depict the size of the dot that is placed in a matrix i.e. there are a several dots within the graph but
the alter in size due to their "market share".

Anyone have an idea how I can do that?

I attached a picture so you know what I mean. I tried to look for templates or tutorials but google is being a bitch. (Math, numbers, or graphs are not really my strong suit :P)
