Best Examples of displaying very small spreadsheets, technical info.

It's been said that in order to display a spreadsheet or charts/tables that are easy to see, the designer needs to record using the size of the Story File.  I have tried to do this numerous times, and I have yet to be able to display "quality" images of spreadsheets, tables, charts that the learner can see.  It's a huge part of my work!

I would love to see examples of how others did this successfully.  I don't have the luxury of creating "fun" or "cartoon' type work on slides as I see so often here.  It's very technical. 

Thank you.
