Firstly the X,Y coordinates need to be converted to polar (angle, radius) coordinates. Remember Pythagoras' theorem from school? Bet you thought you would never need that stuff! Anyway, atan2(y,x) and sqrt(x^2 + y^2) will do the job for you.
Also origin moves the graph on the page, it dosn't change the point that the impulse plot uses, I don't really know if this can be done. I just subtracted the origin values from your X,Y coordinates in the geta (get-angle) and getr (get-radius) functions:
Hi again. Sorry if it seems like I'm spamming the boards a bit, but I figured I might as well ask all the questions I need answers to at once, and hopefully at least get some.

Hi,
I am trying to make a plot of an ASCII file using GNUplot, but I keep getting error msg:
for example plot filename.txt
It says that (.txt ) is not identified ... I tried to write it without the .txt part, but I also get the error msg.
Any idea why? :confused: (1 Reply)
Hi I am trying to fit my histogram data with a gaussian model and am encountering two problems:
1. I can't seem to fit the histogram data with a model
fit y(x) 'bin.txt' using 2:xtic(1) via a,b,c (error: need 2 to 7 using specs)
2. Even when I manually guess the correct parameters for my fit and... (1 Reply)

Hi All,
I am new to Grace and would like to plot histograms. My input files have one column for frequencies and another column for distances, for example:

I am new to R and would like to calculate the percentage frequency distribution of h1 and h2. How can I combine h1 and h2 in one plot? I tried the following code.
h1=c(5.18,4.61,3.30,7.58,3.00,3.80,1.95,2.67,2.77,2.73,2.33,3.36,3.50,1.91,4.25,3.87,2.86,2.26,2.00,3.86,3.33,3.59,4.00)... (0 Replies)
Hi,
I have 2 files with similar structure - reference and test that I would like to BIN both and generate the comparison.
input files structure is:
a 3
b 10
c 3
d 7
e 1
f 4
g 9
h 6
I would like the output to be (lets say both reference and test are the file above - no diff)

gsl-histogram
GSL-HISTOGRAM(1) General Commands Manual GSL-HISTOGRAM(1)NAME
gsl-histogram - compute histogram of data on stdin
SYNOPSYS
gsl-histogram xmin xmax [n]
DESCRIPTION
gsl-histogram is a demonstration program for the GNU Scientific Library. It takes three arguments, specifying the upper and lower bounds
of the histogram and the number of bins. It then reads numbers from `stdin', one line at a time, and adds them to the histogram. When
there is no more data to read it prints out the accumulated histogram using gsl_histogram_fprintf. If n is unspecified then bins of inte-
ger width are used.
EXAMPLE
Here is an example. We generate 10000 random samples from a Cauchy distribution with a width of 30 and histogram them over the range -100
to 100, using 200 bins.
gsl-randist 0 10000 cauchy 30 | gsl-histogram -100 100 200 > histogram.dat
A plot of the resulting histogram will show the familiar shape of the Cauchy distribution with fluctuations caused by the finite sample
size.
awk '{print $1, $3 ; print $2, $3}' histogram.dat | graph -T X
