Is rainflow applied on a graph or some vector?

The Mathworks supplied rainflow routine is documented as expecting a vector of single or double .
The File Exchange contributions I pointed out to you were created before matlab added graph objects . They expect data not objects.

in help section it is written that the output rm of the rainflow function is as follows
%%%%%%%%%%%%
rm — Rainflow matrix
matrix
Rainflow matrix. The rows of rm correspond to cycle range, and the columns correspond to cycle mean
but when the histogram is plotted and the the sum of these rows correspond to counts of a specific range
CAN YOU PLEASE CLEAR THIS CONFUSION OF MINE I WOULD REALLY BE THANKFUL

I do not see any contradiction there. The rm matrix is a 2D histogram, so it makes sense that the sums along the rows or along the columns add up to the totals expected for that class. The bin locations are returned in the next two output arguments after rm.
