Both very clever indeed. Output is correct if theres only one column. However, a little more assistance please. If the csv is as follow, how do I get it to convert the bitrate columns (data1, data2, data3) without having to parse the file first?
Don - Your method only outputs if the data is in the first column.
Chubler - Your method outputs the wrong data.
Additionally, I'd like to be able to call the script and give it an input file from the shell prompt rather than explicitly calling the file in the script. For example:
Thanks again.

Hello guys!
I have some issue in how to processing some data.
I have some files with 3 columns. The 1st column is a name of my sample. The 2nd column is a numerical sequence (very big sequence) starting from "1". And the 3rd column is a feature of each line, represented for a number (completely... (2 Replies)

kst2
kst(1) kst2 kst(1)NAME
kst -- plots scientific data
SYNOPSIS
kst
kst [ -F DATASOURCE ] [ -f STARTFRAME ] [ -n NUMFRAMES ] [ -s FRAMESPERSAMPLE [ -a ] ] kstfile
kst datasource [ -f STARTFRAME ] [ -n NUMFRAMES ] [ -s FRAMESPERSAMPLE [ -a ] ] [ -P PLOTNAME ] [ -A] [ -d ] [ -l ] [ -b ] [ -x FIELD ]
[ -e FIELD ] [ -r RATE ] [ -y FIELD ] [ -p FIELD ] [ -h FIELD ] [ -z FIELD ] [ --png filename ] [ --print filename [ --landscape |
--portrait ] [ --Letter | --A4 ] ]
DESCRIPTION
kst is a graphical data plotting tool, which includes the ability to plot live data (contiuously update the plot as new data becomes avail-
able).
kst may be run entirely from within its GUI, in which case no command line arguments are needed. kst has a powerful wizard for easily set-
ting up new plots.
In the second invocation, kst loads pre-saved plot specifications from the file kstfile and optionally may override some of the settings in
that file.
In the third invocation, kst displays plots of the data as directed in the default manner. Additional datasources may be specified on the
command line with options for that datasource following it. Command line options generally apply to all subsequent options unless later
overridden.
OPTIONS -A plot all curves in separate plots
-a average frames (simple mean) when plotting with -s.
--A4 use A4 sized paper for printing. Requires --print.
-b plot as bargraphs.
-d use points when plotting curves.
-e FIELD
use FIELD as the magnitude of error bars applied to the next plot.
-F datasource
override the datasource indicated in the kstfile and instead use datasource.
-f STARTFRAME
begin plotting at STARTFRAME frames into the data. Set to -1 to start at NUMFRAMES from the end of the data.
-h FIELD
plot FIELD as a histogram.
-l use lines when plotting curves.
--landscape
use landscape orientation for printing. Requires --print.--Letter use US Letter sized paper for printing. Requires --print.
-n NUMFRAMES
plot at most NUMFRAMES frames of data. Set to -1 to indicate all of the data.
-P PLOTNAME
plot all plots in the plot named PLOTNAME.
-p FIELD
plot FIELD as a power spectrum plot.
--png filename
render to a portable network graphics (png) image with file name filename and quit.
--portrait
use portrait orientation for printing. Requires --print.
--print filename
print the plot to file filename and quit.
-s FRAMESPERSAMPLE
plot every FRAMESPERSAMPLE frames when plotting.
-x FIELD
use FIELD as the X-axis vector.
-y FIELD
plot FIELD as an XY plot.
-z FIELD
plot FIELD as an image.
EXAMPLES
Plot all data in column 2 from data.dat.
kst data.dat -y 2
Same as above, except only read 20 lines, starting at line 10.
kst data.dat -f 10 -n 20 -y 2
also read col 1. One plot per curve.
kst data.dat -f 10 -n 20 -y 1 -y 2
Read col 1 from data2.dat and col 1 from data.dat
kst data.dat -f 10 -n 20 -y 2 data2.dat -y 1
Same as above, except read 40 lines starting at 30 in data2.dat
kst data.dat -f 10 -n 20 -y 2 data2.dat -f 30 -n 40 -y 1
Specify the X vector and error bars: Plot x = col 1 and Y = col 2 and error flags = col 3 from data.dat
kst data.dat -x 1 -e 3 -y 2
Get the X vector from data1.dat, and the Y vector from data2.dat.
kst data1.dat -x 1 data2.dat -y 1
Placement: Plot column 2 and column 3 in plot P1 and column 4 in plot P2
kst data.dat -P P1 -y 2 -y 3 -P P2 -y 4
BUGS
Please report bugs to either the kst mailing list at kst@kde.org or to the kde bugzilla under the kst product at http://bugs.kde.org/. If
you can run kst, you can easily report bugs by selecting Bug Report Wizard from the Help menu.
