Excel

Hi Joyce, thanks for your query and welcome to the forum. The link to the dynamic chart I mentioned to you is:

http://chandoo.org/wp/2010/08/31/dynamic-chart-with-check-boxes/

It includes a free spreadsheet download of the chart in action. I hope it proves useful! Good luck in your new job and post any questions here if something arises which you're not familiar with.

All the best,

Anthony
