I have a single file that looks like this:
I am trying to plot a probability distribution/histogram, so I'd like to divide this into bins of of equal width based on the maximum and minimum values, and output the number of items in a bin such that my final output data would be like:
I have tried using something like:
but it doesnt seem to work well as it is too manual. Could someone out here help me out with this?
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)
hello experts,
I have been trying to plot a histogram of a data like;
-54
-56
-43
-65
-67
-78
...
I have 156.000 rows of these kind of values between 0 and -100. I just want to make x axis takes values 5 spacing in between like;
-100 -95 -90 .............. 0

Hi,
I have a situation to compare one file, say file1.txt with a set of files in directory.The directory contains more than 100 files.
To be more precise, the requirement is to compare the first field of file1.txt with the first field in all the files in the directory.The files in the... (10 Replies)
Hello experts,
I'm stuck with this script for three days now. Here's what i need.
I need to split a large delimited (,) file into 2 files based on the value present in the last field.
Samp: Something.csv

bca,adc,asdf,123,13C
def,adc,asdf,123,12A
I need this split... (6 Replies)
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:

4 2.7
5 2.8
2 3.9
2 4.0
4 4.7
4 4.8
4 4.9

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)

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
