Write a program that reads a file with 2 columns:
- time in minutes for the x axis
- value (e.g. temperature, heart freq.) for the y axis

Plot the last m minutes, the y axis shall have a range from min...max.
Start with parameter values m=5, speed s=1, min=20, max=120.
After m=5 minutes, the graphical display shall plot the curve of the
last 5 minutes. In other words, you have to implement a sliding window
with a 5 minute history. This way of displaying measurements is common
for many medical instruments.
The speed s is useful for testing, 1=real time, 10=10 times faster.
To implement the real time behaviour, you have to let the program wait the
time interval between two values. The time interval is not constant.

Any OO programming languages and any graphical libraries are fine,
as long as they are available for Windows and Linux. Examples are
Java, C++, QT, SDL, TCL/TK, Flash, .NET/mono.


A sample file looks like this (lines 1..3 are always comments):
-------8<-------cut-here-------8<-------
Logfile of program temperature_monitor.cpp
Temp sensor #42, range 30..60 degrees Celsius
2007-06-21 20:30
0.017737 45.2
0.045122 42.7
0.073591 43.1
[...]
-------8<-------cut-here-------8<-------

You can download the test data file here:

An axample how the output can look like is here:

Are you asking us to do your homework for you? Have you expended any effort on this yourself?

If you tried posting this in the Jobs Offered forum you might be able to find a contractor willing to quote for this work.

If you are not asking for code to be written for you, then to get help here you really need to explain what you have done so far and where you are stuck.

(See here if you are not sure how to use these forums)
