67 |
68 | Version 2.0 10-Nov-2004
69 |
70 | * The 2.0 version of the gnuplot interface is a cross between the original,
71 | object oriented version, and the version 1.0 which was simply a string
72 | manipulation library.
73 |
74 |
75 | h3. Version 0.9
76 |
77 | bq.
78 | My first attempt at a Ruby interface to gnuplot was an object interface
79 | encapsulating gnuplot language. This was taken directly from the Python
80 | gnuplot interface. In spite of my being very familiar with Gnuplot and
81 | Ruby and being the author of the RGnuplot package, I found it
82 | non-intuitive to use the RGnuplot package. I found myself constantly
83 | looking at the code to figure out what I needed to do.
84 | This was not sufficient and did not sit well.
85 |
86 | h3. Version 1.0
87 |
88 | bq.
89 | The second attempt at a Ruby interface was to do absolutely nothing but
90 | use Ruby's built in string manipulation methods. This meant that I
91 | could simply use my knowledge of Gnuplot without having to worry about
92 | objects.
93 | While in some ways an improvement over Version 0.9, it still did not sit
94 | well with me.
95 |
96 | h3. Version 2.0
97 |
98 | bq.
99 | After attending RubyConf 2004 I was inspired by Rich Kilmer's use of
100 | Ruby to implement domain specific languages. That is the current
101 | implementation of Gnuplot and quite probably the one that I'll stick
102 | with for some time. This version combines the direct mapping of the
103 | gnuplot language without wrapping with the ruby syntax and mechanism of
104 | adding methods to existing classes to interface Ruby objects with
105 | gnuplot.
106 |
107 | h2. Setup
108 |
109 | h3. Version 2.2
110 |
111 | If the 'gnuplot' command is in your path then there is no required
112 | setup. If the gnuplot executable for your system is called something other
113 | than simply 'gnuplot' then set the RB_GNUPLOT environment variable to the
114 | name of the executable. This must either be a full path to the gnuplot
115 | command or an executable filename that exists in your PATH environment
116 | variable.

2 |
3 | p=.

5 | ["Authors":AUTHORS.txt]
6 | ["License":LICENSE.txt]
7 |
8 | h2. History and Background
9 |
10 | Gnuplot is a program that has a rich language for the generation of
11 | plots. It has a unique place in academia as it was one of the first
12 | freely available programs for plot generation. I started using gnuplot
13 | over 10 years ago while pursuing my Master's degree in Physics and have
14 | been using it actively ever since. Now rdp maintains it.
15 | See also the changelog for more detail.
16 |
17 | h2. Pre-requisites and Installation
18 |
19 | 1. (mac) Install XQuartz from here:
20 | @http://xquartz.macosforge.org/landing/@
21 |
22 | 2. Install gnuplot with homebrew (not OS X? install it using your package manager):
23 | @brew install gnuplot --with-x11@
24 |
25 | 3. Install gnuplot gem:
26 | @gem install gnuplot@
27 |
28 | h2. Ruby Gnuplot Concepts
29 |
30 | Gnuplot has a very simple conceptual model. Calls to _Set_ are
31 | made to set parameters and either _Plot_ or _Splot_ is
32 | called to generate the actual plot. The _dataset_ to be
33 | plotted can be specified in a number of ways, contained in a separate
34 | file, generated from a function, read from standard input, or read
35 | immediately after the plot command.
36 |
37 |
38 | The object model for the Ruby gnuplot wrapper directly mimics this
39 | layout and flow. The following are the standard steps for generating a
40 | plot:
41 |
42 |
43 | 1. Instantiate a @Plot@ or @Splot@ object and set parameters by gnuplot variable name.
44 |
45 | 2. Instantiate @DataSet@ objects and attach Ruby objects containing the data to be plotted to the @DataSet@. Attach properties that modify the plot command using the modifier name.
46 |
47 | 3. Send the @Plot@/@Splot@ object to a @Gnuplot@ instance for plotting.
48 |
49 | The Version 2.0 interface makes very heavy use of blocks leading to very
50 | readable code.
51 |
52 | @Gnuplot.open@
53 |
54 | bq.
55 | Instantiates a new Gnuplot process. The path to the executable is
56 | determined on a Unix or MacOSX system using the which command. Windows
57 | users, I have no idea what to do.
58 | If a block is given to the function the opened process is passed into
59 | the block. This mimics the most common usage of the @File.open@ method.
60 |
61 | @Plot.new@
62 |
63 |
64 | @SPlot.new@
65 |
66 | bq.
67 | Create a new @Plot@ or @SPlot@ object. @DataSet@ s are attached to the object
68 | to specify the data and its properties.
69 | If a block is given to the function, the plot object is passed into the
70 | block.
71 |
72 | @DataSet.new@
73 |
74 | bq.
75 | Associates a Ruby object containing the data to plot with the properties
76 | that will be passed to the plot command for that dataset. Any Ruby
77 | object can be associated with a @DataSet@ as long as it understands the
78 | @to_gplot@ method.
79 |
80 | @to_gplot@
81 |
82 | bq.
83 | Within Gnuplot, plot data is read in very simple formats. The
84 | @to_gplot@ method is expected to write the data of the object in a format
85 | that is understandable by Gnuplot. One of the many great things about
86 | Ruby is that methods can be added after the original declaration. The
87 | gnuplot module defines the @to_gplot@ method on the following classes:
88 | @Array@, @String@, and @Matrix@.
89 | Simply define a @to_gplot@ method on your own class to tie the class into
90 | gnuplot.
91 |
92 | h2. Examples
93 |
94 |
95 | h3. Simple sin wave
96 |
97 | bq. The following example simply plots the value of sin(x) between the
98 | ranges of -10 and 10. A few points to notice:
99 |
100 | * The code uses nested blocks to construct the plot. The newly created object is passed to the block so it can be modified in place.
101 |
102 | * Each of the gnuplot plot variables are modified using the variable name as a method name on the plot object or on the dataset object. The wrapper also takes care of the single quoting that is required on some of the variables like @title@, @ylabel@, and @xlabel@.
103 |
104 | * The plot object simply has an array of @DataSet@s. The constructor initializes this empty array before yielding to the block. This method uses the @<<@ operator to add the @DataSet@ to the plot.
105 |
106 | * When the plot block ends, if an @IO@ object is given to the @Plot@ constructor, the plot commands will be written to the @IO@ object. Any object can be passed to the constructor as long as it understands the @<<@ operator.
107 |
108 |
109 | Gnuplot.open do |gp|
110 | Gnuplot::Plot.new( gp ) do |plot|
111 |
112 | plot.xrange "[-10:10]"
113 | plot.title "Sin Wave Example"
114 | plot.xlabel "x"
115 | plot.ylabel "sin(x)"
116 |
117 | plot.data << Gnuplot::DataSet.new( "sin(x)" ) do |ds|
118 | ds.with = "lines"
119 | ds.linewidth = 4
120 | end
121 |
122 | end
123 |
124 | end
125 |
126 |
127 | Or you can write it out to a file (the above snippet displays the graph, in Linux, but in windows you'd need to write it to a file).
128 |
129 | See the file @examples/output_image_file.rb@.
130 |
131 | h3. Plotting discrete points
132 |
133 | Array data can be plotted quite easily since @Array@s have a defined @to_gplot@ method.
134 |
135 | Simply pass an array of data to the constructor of the @DataSet@ object or set the data property of the @DataSet@. In this example, because there are two arrays, each array will be a single column of data to the gnuplot process.
136 |
137 |
138 | Gnuplot.open do |gp|
139 | Gnuplot::Plot.new( gp ) do |plot|
140 |
141 | plot.title "Array Plot Example"
142 | plot.xlabel "x"
143 | plot.ylabel "x^2"
144 |
145 | x = (0..50).collect { |v| v.to_f }
146 | y = x.collect { |v| v ** 2 }
147 |
148 | plot.data << Gnuplot::DataSet.new( [x, y] ) do |ds|
149 | ds.with = "linespoints"
150 | ds.notitle
151 | end
152 | end
153 | end
154 |
155 |
156 | h3. Multiple Data Sets
157 |
158 | As many data sets as are desired can be attached to a plot. Each of these can have their own plot modifiers. Notice in this example how the data array is explicitly set instead of using the @<<@ operator.
159 |
160 | Also in this example, the commands are not written to the Gnuplot process but are instead written to a File called @gnuplot.dat@. This file can later be run directly by a gnuplot process as it contains only the gnuplot commands.
161 |
162 |
163 | File.open( "gnuplot.dat", "w") do |gp|
164 | Gnuplot::Plot.new( gp ) do |plot|
165 |
166 | plot.xrange "[-10:10]"
167 | plot.title "Sin Wave Example"
168 | plot.ylabel "x"
169 | plot.xlabel "sin(x)"
170 |
171 | x = (0..50).collect { |v| v.to_f }
172 | y = x.collect { |v| v ** 2 }
173 |
174 | plot.data = [
175 | Gnuplot::DataSet.new( "sin(x)" ) { |ds|
176 | ds.with = "lines"
177 | ds.title = "String function"
178 | ds.linewidth = 4
179 | },
180 |
181 | Gnuplot::DataSet.new( [x, y] ) { |ds|
182 | ds.with = "linespoints"
183 | ds.title = "Array data"
184 | }
185 | ]
186 |
187 | end
188 | end
189 |
190 |
191 | h3. Miscellanrous
192 |
193 | You can also add arbitrary lines to the output
194 |
195 |
196 | plot.arbitrary_lines << "set ylabel \"y label\" font \"Helvetica,20\""
197 |
198 |
199 | See more in the examples folder. Also since this is basically just a wrapper for gnuplot itself, you should be able to do anything that it can do (demos:
200 | http://gnuplot.sourceforge.net/demo_4.4/ )
201 |
202 | h3. Security
203 |
204 | Note that if you pass any user-controlled strings to the gem, it's possible for an attacker to run arbitrary commands.
205 |
206 | In addition to title, any other graph properties that accept strings should be affected too. they're all passed to the system command. So only use strings you trust.
