Hi!

I have the table below, containing 2 Y-values per X-value, i.e. a minimum
value and a maximum value for every period (X-axis). There are 6 periods.

values from different series can overlap.

What is the best way (graph type) to present this table? I guess some tricks
should be involved.

1975/1980 1981/1985 1986/1990
a 2500 2700 2700 2900 2900 3000
b 2500 2700 2700 3000 2900 3000
c 2500 2700 2700 2900 3000 3200
d 2800 3000 3000 3100 3200 3500
e 2800 3000 3000 3100 3500 3700
f 2500 2700 2700 3000 3200 3500
g 2500 2700 2700 3000 3200 3400
h 3000 3200 3300 3500 3500 4000
i 3000 3200 3300 3500 4000 4200
j 3500 3600 3700 3800 4500 4700
k 3300 3500 3500 3600 4300 4700
l 5000 5200 5500 6500
m 0 0 5000 6000 6000 7000
n 3700 3700 3900 4000 4500


hope someone knows an acceptable answer.. Thanks!
