In the desktop version I was able to do income and expense graphs, do I have the option to do them on the online version as well?

Welcome to the Community, @fernan.

At this time, you'll have to export the reports to Excel and manually create the graphs. I'm going to submit feedback to our Product Development Team about bringing in a feature that will allow graph reports for QuickBooks Online. You can visit our Blog to see what's new to QuickBooks. 

If you have additional questions or concerns, please don't hesitate and leave me a Reply. I'm always here to help.

Please add graphs to QB online, I'm so disappointed, I wanted to make a quick presentation to investors and was sad to find our that QB online does not offer that.  

The voice of our customer is our priority, @esh2020.

I can see how having this option would be helpful for you and your business. Rest assured, our Product Developers are working hard and always looking for ideas to consider on how to improve QuickBooks.

In the meantime, you can follow what my colleague Ashley H suggested above as a workaround. I also added a link here for your future reference in case you need some information about QuickBooks: Help articles.

Please know that I'm just a post away if you have any other questions you can get back to us anytime.
