Difference between Total equity and Realized equity?

I have attached a screen shot .png of a graph.

It is of someones results, who or what doesn't matter, but what does it mean
Total equity and Realized equity?

Thanks

realized one must be the balance and the one below is the flowting equity(not realizet account value) witch also reflect temporaly not realised drowdowns of the system.

Realized is closed trades.... Total equity includes open trades.

Realized equity (should be just 'balance' ?) shows the total in the account not including current open positions.

Total equity (should be just 'equity' ?) shows current balance including all open positions, or in other words, if this trader would close all open positions his Realized equity (balance) would become equal to the current Total equity.

Thank you, so if the total equity goes below 0 like it did in that graph a couple of times, then that is an account blow up correct?
