【 摘 要 】

We study the enumeration of bargraphs with respect to some corner statistics. We find generating functions for the number of bargraphs that track thecorner statistics of interest, the number of cells, and the number of columns.We also consider bargraph representation of set partitions and obtain someexplicit formulas for the number of specific types of corners in such representations.
