Amending Graph Designs

Content

Morning all

I've built a Performance Dashboard (attached), but had a few questions that I haven't yet found answers to:

1. I'd like to change the colours of the graphs so they both aren't blue. Is there any way to do this?

2. How do I add the numerical data on to each of the graph columns? Only I will have access to the dashboard so information will be shared via screen prints / PDFs. It would be good to have the numerical values on the columns, as it is only really available when I hover over each column

Thanks!
