Dear all,

I want to design a histogram and I need to have the frequency at certain
points. For example I have the following 2 columns:

*X      Y*

0.1    25
0.4    22
0.45  11
0.55  21

I want the chart to have 4 columns. First column is from 0.0-0.1 (on X) and
frequency is 25. Next colum is wider and form 0.1-0.4 with 22 frequency.
Next column is narrow with 11 frequency and the last column is the same as
the first one with 21 frequency.

Can anybody tell me how I can have this chart.

Thanks,
Mohsen
