For example, I have a file called data.txt. And the content is:
May I know how to write a script for gnuplot, so I can have a bar graph as the column 1 will be the x and column 2 will be the y? And I hope that the x value can be seen clearly. Thank you
So, far here is my code
But the final outcome, the x value will overlapped with each other because x value has a long name.

I am trying to get sed, tr or awk to search a file that contains records with fields delimited by the vertical bar | and replace the occurrences in the records where the vertical bar is preceded by a space " |" with a vertical bar.

Hi,
i would like to change color depending from the valuerange.
a gnuplot-script will generate a multiplot and in one graph,
the ranges should have different colors, e.g.
100 ... 133 --> red
200 ... 233 --> blue
300 ... 333 --> orange
400 ... 433 --> green

I'm not able to find a solution because I cant find the exact keyword for this.
I wanna make a graph like ive shown in the attachment.
Could someone please share ideas on how to do this.
Thanks! (3 Replies)
Hello. I need to draw many lines with multicolor (color is set by some pixmap (xpm)) on C++ with standart libs.
Horizontal lines are drawing succsessfully with GC and XSetTile. But non-horizontal - no good.
I rotate pixmap for all lines and then XSetTile for each line with own pixmap, but it's... (1 Reply)
Let me start by saying I'm new to gnuplot and not very good at unix at all..
Anyway, I'm each minute measuring temperature and humidity and saves the last 60 readings along with time in a textfile, values_minute.
The contents of the file is formatted like this: time temperature humidity

I have a shell script which executes to write html codes into a text file. My next step is to email the text file so that receiving person (people who i send email to) should be able to see pie/chart or bar graph (whatever i design in my code) in their email.

graph::transitiveclosure
Graph::TransitiveClosure(3pm) User Contributed Perl Documentation Graph::TransitiveClosure(3pm)Graph::TransitiveClosure - create and query transitive closure of graph
SYNOPSIS
use Graph::TransitiveClosure;
use Graph::Directed; # or Undirected
my $g = Graph::Directed->new;
$g->add_...(); # build $g
# Compute the transitive closure graph.
my $tcg = Graph::TransitiveClosure->new($g);
$tcg->is_reachable($u, $v) # Identical to $tcg->has_edge($u, $v)
# Being reflexive is the default, meaning that null transitions
# (transitions from a vertex to the same vertex) are included.
my $tcg = Graph::TransitiveClosure->new($g, reflexive => 1);
my $tcg = Graph::TransitiveClosure->new($g, reflexive => 0);
# is_reachable(u, v) is always reflexive.
$tcg->is_reachable($u, $v)
# The reflexivity of is_transitive(u, v) depends of the reflexivity
# of the transitive closure.
$tcg->is_transitive($u, $v)
# You can check any graph for transitivity.
$g->is_transitive()
my $tcg = Graph::TransitiveClosure->new($g, path_length => 1);
$tcg->path_length($u, $v)
# path_vertices is automatically always on so this is a no-op.
my $tcg = Graph::TransitiveClosure->new($g, path_vertices => 1);
$tcg->path_vertices($u, $v)
# Both path_length and path_vertices.
my $tcg = Graph::TransitiveClosure->new($g, path => 1);
$tcg->path_vertices($u, $v)
$tcg->length($u, $v)
my $tcg = Graph::TransitiveClosure->new($g, attribute_name => 'length');
$tcg->path_length($u, $v)
DESCRIPTION
You can use "Graph::TransitiveClosure" to compute the transitive closure graph of a graph and optionally also the minimum paths (lengths
and vertices) between vertices, and after that query the transitiveness between vertices by using the "is_reachable()" and
"is_transitive()" methods, and the paths by using the "path_length()" and "path_vertices()" methods.
For further documentation, see the Graph::TransitiveClosure::Matrix.
Class Methods
new($g, %opt)
Construct a new transitive closure object. Note that strictly speaking the returned object is not a graph; it is a graph plus other
stuff. But you should be able to use it as a graph plus a couple of methods inherited from the Graph::TransitiveClosure::Matrix class.
Object Methods
These are only the methods 'native' to the class: see Graph::TransitiveClosure::Matrix for more.
is_transitive($g)
Return true if the Graph $g is transitive.
transitive_closure_matrix
Return the transitive closure matrix of the transitive closure object.
INTERNALS
The transitive closure matrix is stored as an attribute of the graph called "_tcm", and any methods not found in the graph class are
searched in the transitive closure matrix class.
