Hello,
@bigblue Thanks for letting me know. There are no settings. Did you check with one theme or many? This sounds a lot like a CSS issue. Can you show me a screenshot or give me access to a site?
@jamiej I am not sure why you reinstalled wordpress, at the very least you could downgrade to the previous version of the Exchange extension. These things are usually CSS issues. It is near impossible to predict what CSS rules a theme has, I’m just aiming to make something that works with a few standard themes, glad you found a solution. The graph already has the red/green colors that you set in customizer. In a later version I may add more styling controls in customizer.
with regards
