PL chart as the name says is a powerful indicator that plots a profit/loss bar chart for your account irrespective of the chart currency. Each bar in PL chart represents profit or loss made from the respective bar on the terminal chart. This feature makes it convenient in that you can view monthly, weekly, daily, hourly, minutely and so forth profit or loss by simply changing the chart timeframe.
