i have a bunch of csv files generated daily.
I need a program that can read these data and generate meaningful table and chart daily and weekly.
I will post more info later.

I need a program to do two task, or two programs to do single task each.
Data will typically look like this:
The first column is date, the second column is time, and third column is quantity.
1) A program that takes a date range and plot the graph for each row with Y axis the quantity. Typically I can have several thousand rows for each day. So I must be able to specify a date and hour range
For example, from the above sample data, the day 1 chart:
the X value is 4.07am, the Y value is 0
the X value is 4.09am, the Y value is 3
the X value is 2.11pm, the Y value is 2
2) A program to generate cumulative chart and table. I specify a date range (such as a few days, or weeks or months) and it show the total of everyday on the Y axis.
For example, from the above sample data, a weekly chart:
for day 1, the Y value is 5.
for day 2, the Y value is 1.
for day 3, the Y value is 3.
