25 *PyPlotSuite* is a set of graphical tools to quick visualize and explore/analyze
26 monodimentional and bidimensional data. The plot produced can be saved in a
27 variety of image formats to produce publication quality graphs.
29 At the moment the project is composed by two little stand alone applications:
30 *ImageAnalyzer* and *Plotfile2*. ImageAnalyzer is focused towards images (or any
31 2D data, such as arrays) visualization, analysis, and measurement. Plotfile2
32 focus is towards simple data series visualization, with the possibility to
33 quick modify many plot characteristics. Both applications can save the result
34 on a multitude of image file formats (png, eps, jpeg, pdf, and more).
36 PyPlotSuite is written in python, using the GTK gui toolkit (through the python
37 binding pygtk, and using Glade-2 to layout the windows). All plots are created
38 with the great Matplotlib python 2D graphic library. Matplotlib is such a good
39 tool that the PyPlotSuite applications are only tiny wrapper around Matplotlib
40 functionality. Also some Numpy functionality are used both through Matplotlib
41 (which requires Numpy) and both directly.
43 Home Page:: http://pyplotsuite.sourceforge.net[]
44 *Latest Version*:: 0.1-alpha7
52 Only Plotfile2 changes in this release. Various speed-up and code optimization, and the support for changing also the color for all line-plot elements.
56 This is the first version of PyPlotSuite released as a single tarball. It
57 includes both ImageAnalyzer and Plotfile2.
59 A new plot property dialog in Plotfile2 allows to change many plot parameters
60 (line style and width, marker style and size). There's also the GUI for
61 changing the colors of the various plot elements but this functions is not
62 implemented in the underlying code yet.
68 Early versions of *ImageAnalyzer* and *Plotfile2* were released in separated
69 tarballs with separated version number. Now they are released together in the
70 same tarball with the same version number (and I plan to integrate them more).
71 However they retain separated changelogs, so you can keep track of each
72 application separately.
74 The development version of *PyPlotSuite* is hosted on a
75 http://repo.or.cz/w/pyplotsuite.git[git repository]. To download the latest
76 (possibly broken) development version just install http://git.or.cz/[git]
80 $ git clone ssh://repo.or.cz/srv/git/pyplotsuite.git
83 Now you have a complete working version of PyPlotSuite to test/hack on. If git
84 and cogito does not work on your OS (i.e. windows) look at
85 http://bazaar-vcs.org/[bazar] that is multiplatform SCM with a git plugin too.
91 You must have this software installed in order to be able to run the program:
93 - Any recent version of Linux, Mac OSX or Windows
95 - Python 2.4 or newer (2.3 may still work, not tested):
96 http://www.python.org[]
99 http://www.pygtk.org/[]
101 - NumPy (1.0 or newer)
102 http://numpy.scipy.org/[]
104 - MatPlotLib (0.87 or newer):
105 http://matplotlib.sourceforge.net/[]
107 - SciPy (only the module scipy.ndimage.filters):
108 http://www.scipy.org/[]
110 - Python Image Library (PIL):
111 http://www.pythonware.com/products/pil/[]
113 NOTE: Typically Numpy is a prerequisite for Matplotlib, so you may have
114 installed it in bundle with Matplotlib.
116 NOTE: The Scipy module and the PIL library are a requirement only if you want
117 to run ImageAnalyzer. Plotfile2 does not requires them.
123 Name:: Image Analyzer
124 Description:: A tool to extract and make measures on scientific images.
130 ImageAnalyzer is a python[1] program written with the purpose to analyze
131 scientific images to extract information such dimensions, and to reveal some
132 subtle features. You can also create and save publication quality figures in a
133 variety of hard-copy formats (using Matplotlib[5]).
135 To execute the program type:
138 python imageanalyzer.py
141 Remeber to check the software requirement above.
144 Image formats supported
145 ~~~~~~~~~~~~~~~~~~~~~~~
147 All format supported by the PIL[6] library, with the following pixel formats:
148 - L (Luminance, aka black&white) 8 bit and 14 bit
149 - RBG(A) with 8bit per channel
155 The features currently implemented are:
157 - Load, zoom and navigate on any RBG(A) or L (Luminance, aka black&white)
159 - The possibility to choose one of the following 17 interpolation algorithms:
160 Bessel, Bicubic, Bilinear, Blackman, Catrom, Gaussian, Hamming,
161 Hanning, Hermite, Kaiser, Lanczos, Mitchell, Nearest, Quadric, Sinc,
163 The default one is Nearest which is, in a way, "absence of interpolation".
164 - Select one of the 14 color-maps (only for L images)
165 - Select a dynamic range either numerically and graphically through an
166 histogram of the image (only for L images).
167 - Grid on/off, black/white (to match various color-maps).
168 - Calculate the distance between two points with the option to set the pixel
169 dimension for the image (x and y separately).
170 - Plot the pixel-precise profile of an arbitrary number of sections of the
171 image (only for L images).
178 Description:: A tool plot 1D data series.
184 Plotfile2 is is a python[1] program written with the purpose to quick plot data
185 series stored in standard ascii text files. Multiple data series can be plotted,
186 compared and the resulting plot can be saved in a variety of image file formats
187 with a customizable size and resolution. This feature come particularly handy
188 if you want to embed your plot in a document and you what size the final image
191 Plotfile2 is written using the GTK toolkit[2] and embeds Matplotlib[5] plot
194 To execute the program, enter the Plotfile2 dir and type:
200 See also the software requirements above.
206 At the moment Plotfile2 can:
208 - Load one or more data series from a two column (spaces or tab separated)
209 ascii file. Blank lines (only spaces or tabs) are ignored.
210 - Detect if there is an header to automatically set axis labels. The header
211 must be a line with two strings separated by spacing (or tabs). Blank
212 lines before and after the header are ignored. More than two
213 space-separated string results in an error.
214 - Controls to change the X and Y axis range, scale (linear or log) and
216 - Controls to toggle if plot shows points (markers), lines or both.
217 - Complete customization of plot elements through a dedicated dialog
218 (line style, marker type, colors).
219 - Set the plot title and axis labels
220 - Set the figure size (both in inches or in cm) and resolution (in dpi).
221 This is useful to export a plot to be included in a document with a know
223 - Navigate/explore plots (zoom, un-zoom, pan, etc) with the Matplotlib
225 - Save the plot in a multitude of image formats (png, jpeg, eps, pdf, ...
226 all the formats supported by Matplotlib)
232 - Possibility to customize plot line style, line color, line width, marker
233 color, marker size, marker type for each series. *[COMPLETED]*
234 - Possibility to use spline interpolation (with various orders), and
235 exponential-spline interpolation.
238 Plotfile2 Known Problems
239 ~~~~~~~~~~~~~~~~~~~~~~~~
240 - When you change figure size and resolution using the dedicated dialog, the
241 main window may show a scrambled plot (or only an corner of the entire plot).
242 This is only a visualization issue. Therefore, if you save the file (without
243 resizing the window!) you will obtain the image file with the correct size
244 and resolution ready to be included in your documents.
