    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 :-)
