Hey! I think what you want to draw is:
x-axis: deaths/10,000 people/year
y-axis: the 3 systolic groups (120-139, 140-159, >160)
For each systolic group draw 3 bars representing the 3 categories of diastolic pressure.

So....you should have a graph with 9 bars (3 categories for systolic pressure on x-axis x 3 bars for each systolic pressure category).

Hope that makes sense :-)
