The data table won't display totals. However, you could show the totals
with the X axis label:
In the data source table, insert a row between the X Axis labels, and
the first row of data.
In the cell below the first label, enter a formula that refers to the
cell with the label, and the cell with the total, e.g.:
=B1 & CHAR(10) & B8
Copy this formula across to the last column of data.
Select the chart
Choose Chart>Source Data
On the Series tab, for Category (X) axis labels, select the cells that
contain the above formula
