Clarification needed about equity and drawdown

 

I am a newb so sorry if this is a simple question. I need to know what the relationship between

equity and drawdown(absolute, relative, maximal) as it pertains to the tester chart for the EA.

What does it mean when the equity is above the balance on the chart and what does it mean if it is below?

Any help will be greatly appreciated. I have 3 examples below:
