25 *PyPlotSuite* is a set of graphical tools to quick visualize and explore/analyze
26 monodimentional and bidimensional data. The plot created 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
51 * Added multiplatform installer using distutils. Now to install the pyplotsuite
52 system-wide just do "python setup.py install" form the source tree with
53 administrative privileges.
54 * Various bug-fixes thanks to David Trémouilles' bug reports and patches (now
55 the open dialog remebers the last dir).
56 * scipy.filters is now only optional to run ImageAnalyzer
57 * ImageAnalyzer: Allow to change aspect ratio for images in ImageAnalyzer (via
58 the pixel dimesion dialog)
59 * ImageAnalyzer: Zemax file format loading fixes and autodetection improvements.
64 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.
68 This is the first version of PyPlotSuite released as a single tarball. It
69 includes both ImageAnalyzer and Plotfile2.
71 A new plot property dialog in Plotfile2 allows to change many plot parameters
72 (line style and width, marker style and size). There's also the GUI for
73 changing the colors of the various plot elements but this functions is not
74 implemented in the underlying code yet.
80 Early versions of *ImageAnalyzer* and *Plotfile2* were released in separated
81 tarballs with separated version number. Now they are released together in the
82 same tarball with the same version number (and I plan to integrate them more).
83 However they retain separated changelogs, so you can keep track of each
84 application separately.
88 You can decompress the archive where you want and then execute PyPloSuite in
89 place, entering the directory and typing:
101 You can install PyPlotSuite system wide with this command:
104 python setup.py install
111 The development version of *PyPlotSuite* is hosted on a
112 http://repo.or.cz/w/pyplotsuite.git[git repository]. To download the latest
113 development version just install http://git.or.cz/[git]
117 $ git clone ssh://repo.or.cz/srv/git/pyplotsuite.git
120 Now you have a complete working tree of PyPlotSuite to test/hack on. If git
121 and cogito does not work on your OS (I think only windows is affected) look at
122 http://bazaar-vcs.org/[bazar] that is multiplatform SCM with a git plugin too.
128 You must have this software installed in order to be able to run the program:
130 - Any recent version of Linux, Mac OSX or Windows
132 - Python 2.4 or newer (2.3 may still work, not tested):
133 http://www.python.org[]
136 http://www.pygtk.org/[]
138 - NumPy (1.0 or newer)
139 http://numpy.scipy.org/[]
141 - MatPlotLib (0.87 or newer):
142 http://matplotlib.sourceforge.net/[]
144 - SciPy (only the module scipy.ndimage.filters):
145 http://www.scipy.org/[]
147 - Python Image Library (PIL):
148 http://www.pythonware.com/products/pil/[]
150 NOTE: Typically Numpy is a prerequisite for Matplotlib, so you may have
151 installed it in bundle with Matplotlib.
153 NOTE: The Scipy module and the PIL library are a requirement only if you want
154 to run ImageAnalyzer. Plotfile2 does not requires them.
160 Name:: Image Analyzer
161 Description:: A tool to extract and make measures on scientific images.
167 ImageAnalyzer is a python[1] program written with the purpose to analyze
168 scientific images to extract information such dimensions, and to reveal some
169 subtle features. You can also create and save publication quality figures in a
170 variety of hard-copy formats (using Matplotlib[5]).
172 To execute the program type:
178 Remeber to check the software requirement above.
181 Image formats supported
182 ~~~~~~~~~~~~~~~~~~~~~~~
184 All format supported by the PIL[6] library, with the following pixel formats:
185 - L (Luminance, aka black&white) 8 bit and 14 bit
186 - RBG(A) with 8bit per channel
192 The features currently implemented are:
194 - Load, zoom and navigate on any RBG(A) or L (Luminance, aka black&white)
196 - The possibility to choose one of the following 17 interpolation
198 Bessel, Bicubic, Bilinear, Blackman, Catrom, Gaussian, Hamming,
199 Hanning, Hermite, Kaiser, Lanczos, Mitchell, Nearest, Quadric, Sinc,
201 The default one is Nearest which is "no interpolation".
202 - Select one of the 14 color-maps (only for L images).
203 - Select a dynamic range either numerically and graphically through an
204 histogram of the image (only for L images).
205 - Grid on/off, black/white (to match various color-maps).
206 - Calculate the distance between two points with the option to set the pixel
207 dimension for the image (x and y separately).
208 - Plot the pixel-precise profile of an arbitrary number of sections of the
209 image (only for L images).
215 To-do list in no particular order:
217 - Allow to save modified images.
218 - Allow to save/load plot properties (colormap, interpolation, zoom).
219 Handle this as explained in Plotfile2 TODO (below).
220 - Allow to choose font size for title and labels (separately).
221 - Fix axis apect ratio in histogram window.
222 - Better handling of failure on file load.
223 - Use Plotfile2 (instead of the current custom window) to show image
225 - More image filtering options.
226 - Add pixel-value picker tool.
227 - Peak integration tool (2d integration on an elliptical area).
228 - Noise removal tools (dithering, noise shaping, 2D matched filter, you
236 Description:: A tool plot 1D data series.
242 Plotfile2 is is a python[1] program written with the purpose to quick plot data
243 series stored in standard ascii text files. Multiple data series can be plotted,
244 compared and the resulting plot can be saved in a variety of image file formats
245 with a customizable size and resolution. This feature come particularly handy
246 if you want to embed your plot in a document and you what size the final image
249 Plotfile2 is written using the GTK toolkit[2] and embeds Matplotlib[5] plot
252 To execute the program, enter the Plotfile2 dir and type:
258 See also the software requirements above.
264 At the moment Plotfile2 can:
266 - Load one or more data series from a two column (spaces or tab separated)
267 ascii file. Blank lines (only spaces or tabs) are ignored.
268 - Detect if there is an header to automatically set axis labels. The header
269 must be one line with two strings separated by spacing (or tabs). Blank
270 lines before and after the header are ignored. More than two
271 space-separated string results in an error.
272 - Controls to change the X and Y axis range, scale (linear or
273 log) and toggle grid.
274 - Controls to toggle if plot shows points (markers), lines or both.
275 - Complete customization of plot elements through a dedicated dialog
276 (line style, marker type, colors, etc...).
277 - Set the plot title and axis labels
278 - Set the figure size (both in inches or in cm) and resolution (in dpi).
279 This is useful to export a plot to be included in a document with a know
281 - Navigate/explore plots (zoom, un-zoom, pan, etc) thanks to the Matplotlib
282 NavigationToolbar2 (try to click on the crossed arrows icon and then
283 click and dragg with the right mouse button).
284 - Save the plot in a multitude of image formats (png, jpeg, eps, pdf, ...
285 all the formats supported by Matplotlib). Just click on the floppy icon.
291 - Possibility to customize plot line style, line color, line width, marker
292 color, marker size, marker type for each series. *[COMPLETED]*
293 - Possibility to use spline interpolation (with various orders), and
294 exponential-spline interpolation '[Work in progress]'.
295 - Add dialogs to choose an arbitrary color for plot elements in
296 the "Plot Properties" dialog.
297 - Allow font size (and if possible) font style change for labels and title.
298 - Save plots as data (two columns ascii file or csv). This is useful for
299 new data generated by the interpolation.
300 - Allow to save and load plot properties associated with a set of data. This
301 would allow to load a dataset with associated plot style. To maintain the
302 data in a compatible format this metadata will be saved in a new file with
303 same name but different extension (f.e. ".plot"). Maybe the file should
304 be hidden... (in the same dir of the data of course).
305 - Add basic operators (spectrum, intergrate, differentiate: which make sense?).
306 - Embed an (optional) [i]python shell.
309 Plotfile2 Known Problems
310 ~~~~~~~~~~~~~~~~~~~~~~~~
311 - When you change figure size and resolution using the dedicated dialog, the
312 main window may show a scrambled plot (or only an corner of the entire plot).
313 This is only a visualization issue. Therefore, if you save the file (without
314 resizing the window!) you will obtain the image file with the correct size
315 and resolution ready to be included in your documents.
