[gradsusr] Histogram from Timeseries Analysis

[Mohsen Soltani]

Dear Stephen,

I was watching your posts - you and Mary, and said to myself, OK! let's try
to make a time series plot based on your example script!
It was very good and the attached plot is my output. I applied this script
for a weather station in north of Iran viz Rasht station - in southern
coasts of Caspian Sea. I used daily precipitation data compiled by
APHRODITE's Water Resources in the year 1995, just as an example.

Now, I have a question: is it possible to define a specific period of time
to draw time-series plot? For example, imagine we have a daily
precipitation data for 12-months in one year, say 1995,  I would like to
plot the histogram of only between the e.g. April and June, how should I
set time to do so?

Any suggestion?

Thank you,
Mohsen
