+    axes_all : list of Axes
+        A flat list of Axes. Note that you can also access this directly
+        from the grid. The following is equivalent ::
+
+            grid[i] == grid.axes_all[i]
+            len(grid) == len(grid.axes_all)
+
+    axes_column : list of list of Axes
+        A 2D list of Axes where the first index is the column. This results
+        in the usage pattern ``grid.axes_column[col][row]``.
+    axes_row : list of list of Axes
+        A 2D list of Axes where the first index is the row. This results
+        in the usage pattern ``grid.axes_row[row][col]``.
+    axes_llc : Axes
+        The Axes in the lower left corner.
+    ngrids : int
+        Number of Axes in the grid.
