BAR black curve line from distribution plot option

Hello,

I need information regarding the black curve line that comes up in all my plots when I use the distribution plotter option for the BAR plugin (link: https://imagej.net/BAR)

Is there a purpose this curve serves aside from plotting the number of samples and does it have an actual name?
Can it be removed and what would I need to do?

Example:

Thanks in advance!

Yes, Cumulative frequency curve. Currently the only way to disable it is to comment out this line of the code.
