[CSC 335] Hurricane IRMA Makeup Class

[Andrew J. Pounds]

So due to us missing a day as a result of IRMA, I am required by SACS to 
either have an additional class meeting with you all or give you an 
exercise to be completed outside of class.    I think you all would 
prefer the out of class exercise.   It also gives me an opportunity to 
get you up to speed on plotting -- which is going to be critical in the 
next few weeks.

The dataset for HW 3 is now on the class website.   Your exercise is to 
PLOT this dataset using gnuplot on cobra and to e-mail me a postscript 
file of the plot by *Friday night at midnight*.   To help you, I have 
provided an example of how to use gnuplot to not only read and plot 
data, but how to plot multiple data files on top of each other and 
produce a postscript file.  You will find this on the class web page in 
the Examples section (at the top of the page).

You will have to make some small modifications to this file that should 
be obvious (at this point you aren't plotting your fit data, only the 
actual data).  Make a file containing these commands (like the example) 
and call it something like "plotpoints".  Save this on cobra in the same 
location as the datafile.

Then, open gnuplot and run the file

gnuplot
call "plotpoints"
exit

If you are following my example, that should create a file called plot.ps.

On cobra then type the command

ps2pdf13 plot.ps plot.pdf

to convert your file from a postscript file to a PDF file. E-mail me the 
PDF file and the gnuplot file you used (your plotpoints file) to create it.


If you have any questions or have difficulty with this let me know.  
Friday afternoon and evening are going to be busy and my turnaround time 
for questions near the actual due time will be limited.
