I have a question about using sparkline graphs on dashboards between people with varying versions of Excel, some who have downloaded the sparkline add-in and some who have not.

How can I get my sparkline bullet graphs to work on all computers?

Also, and even more important, why is it that only three types of graphs are showing up on my ribbon for sparklines? I have Line, Column and Win/Loss. Where are the bullet graphs?

Thank-you for any help you may be able to provide!
