How to compare two resouce

Hello!
The same task has two time periods, such as planned start time, planned end time and actual start time, and actual end time. How can I compare and display the resource diagram of these two times?
Thank you very much!

Hello,
The following article explains how to add resource views:
https://docs.dhtmlx.com/gantt/desktop__resource_management.html#resourceviewpanel
Here are examples of how it works:

But there are many ways to configure it. Please, send me an image of how you imagine it should look.

Thanks for your reply,
I think I have found what I want to achieve!Just like this baseline example.
