A crosstab can contain up to three different percentages--rows add up to
100%, columns add up to 100%, all cells add up to 100%. Which of these do
you want in your chart?

Thank you for the answers, but let me clarify my concern:
I have used the scale to 100% feature in the GUI (when you click on the
figure and then edit).
But the proportions in each bar are just wrong.
Let me explain:
I did the cross tab between two variables BP and 'High blood pressure'?
When I look at the crosstab notice the distribution of BP given the answer
YES is 41.7 (normal) 29.2% (elevated) and 29.1% (high). Now I also have the
bar graph between these same two variables, scaled to 100%. When I look at
the stacked bar under YES I clearly see the proportions are different here
for normal, elevated and high, they are what is in the crosstab. Clearly
something is wrong with they way graph treats the variables, even though it
adds up to 100%.
I hope this is clear and if anyone can help me put what I see in a crosstab
onto a stacked bar graph, I will really appreciate it.
