XY chart binding & customize

I'm trying to create a bar chart with an xy chart, the problem is that I want to create a category for each machine with data from the historian tag where the data is kWh which continues to increase in value without resetting. 1 bar represents 1 month of kWh usage so the data is kWh now-kwh prev, is it possible?, I'm still new to ignition
