Creating graphs
Platform: solaris 9 x86


I want to be able to create excel like line graphs with basic input data and use it on a webpage or worst case so I can use it to insert to a document

type of input file I would have, example below

datainput.txt:
Code:
date,requests,failures,success
20100501,80,10,70
20100502,75,5,70
20100503,85,25,60
20100504,66,6,60

I know there are various freeware tools to help but I don't have any experience with them and need some help.

Preferably could someone advise for free ware tool I could use and an example of how to use it graphing the data from input file such as the example above

can you help?
I am used to ksh scripting and the various flavours of unix.
Any help would b appreciated.

Hi,
have a look at GNUPlot, gnuplot homepage, that has helped me a lot before. Easy to use in any script based context.

Best regards,

Thanks

any chance you can post example of data file you had and commands you used with gnuplot to plot the data and get output?

Have a look at PSPP: GNU PSPP It is intended as a free replacement for the proprietory software package SPSS and can produce a number of graphs including histograms, pie-charts and box-plots. It supports delimited & fixed-width text, SPSS .sav files and a number of other input file formats. It can also output to HTML (among other formats) and the accompanying documentation is very well written.

Hi!
Sure. Here's a very trivial example; I weighed myself a few times, usually morning and afternoon, recorded the weights with date in a file like this, file vikt.dat:
Code:
2009-Dec-14_17:21 87.70  88.50
2009-Dec-17_08:27 87.65  88.75
2009-Dec-17_14:17 87.80  88.55
2009-Dec-18_10:23 87.40  88.30
2009-Dec-18_14:21 88.45  87.65
2009-Dec-18_19:13 88.25  87.75
2009-Dec-19_08:18 87.50  87.60
2009-Dec-19_13:54 87.75  87.25
2009-Dec-20_14:36 87.90  87.30
2009-Dec-21_15:32 88.90  87.45
2009-Dec-21_16:55 88.00  89.20
2009-Jan-07_14:48 88.05  87.95
2009-Jan-09_11:41 88.50  87.65

Then I used this script for gnuplot to plot the data into a line graph, vikt.plot:
Code:
set xdata time  # The x axis data is time
set timefmt "%Y-%b-%d_%H:%M"
set format x "%d %b"
with linespoint
plot [] [85:91]  'vikt.dat' using 1:2 with linespoint

and call the script from the command line or a script with:
Code:
gnuplot -p vikt.plot

And there are as You can see on their web site, lot's of formats for graphs, ability to export to different graphic file formats, etc, this is just a very simple example.

Best regards,
Lakris

PS I have used it professionally as well Smilie
