# pyevolve-graph(1)

graphical plotting tool for Pyevolve

## NAME

pyevolve-graph - graphical plotting tool for Pyevolve

## SYNOPSIS

**pyevolve-graph**
 \[*options*\]

## DESCRIPTION

This manual page documents briefly the
 **pyevolve-graph**
 command, a graphical plotting tool for programs based on Pyevolve. To use this
 program, you must have **python-matplotlib** and **python-sqlite**
 installed.

## GENERAL OPTIONS

**Pyevolve-pygraph** supports the following options:
 **-h, --help**
 show a brief summary of available options and exit
 **-f** *FILENAME,* **--file=***FILENAME*
 Database file to read from. default is *./pyevolve.db*.
 **-i** *IDENTIFY,* **--identify=***IDENTIFY*
 The identify of evolution.
 **-o** *OUTFILE,* **--outfile=***OUTFILE*
 Write the graph image to a file. Don't specify an extension, just the filename.
 The file will be written in PNG format by default, but this can be changed
 using the **--extension** or **-e** options.
 **-e** *EXTENSION,* **--extension=***EXTENSION*
 Graph image file format. Supported options (formats) are all those supported by
 **python-matplotlib**. Currently, these should be: EMF, EPS, PDF, PNG, PS,
 RAW, RGBA, SVG, SVGZ. Default is PNG.
 **-g** *GENRANGE,* **--genrange=***GENRANGE*
 This is the generation range of the graph. For example, 1:30 would denote
 an interval between 1 and 30.
 **-c** *COLORMAP,* **--colormap=***COLORMAP*
 Sets the Color Map for the graph types **-8** and **-9**. Some options
 are: summer, bone, gray, hot, jet, cooper, spectral. The default is **jet**.
 **-m,***--minimize*
 Sets the 'Minimize' mode. Default is the Maximize mode. This option makes sense
 if you are minimizing your evaluation function.
 **-0**
 Write all standard graphs to file. Equivalent to specifying **-1** **-2**
 **-3** **-4** **-5**.
 **-1**
 Error bars graph (raw scores).
 **-2**
 Error bars graph (fitness scores).
 **-3**
 Max/min/avg/std. dev. graph (raw scores).
 **-4**
 Max/min/avg graph (fitness scores).
 **-5**
 Raw and Fitness min/max difference graph.
 **-6**
 Compare best raw score of two or more evolutions. You must specify the identify
 as a comma-separated list with the **--identify** or **-i** options.
 The maximum is 6 items.
 **-7**
 Compare best fitness score of two or more evolutions. You must specify the
 identify as a comma-separated list with the **--identify** or **-i**
 options. The maximum is 6 items.
 **-8**
 Show a heat map of population raw score distribution between generations.
 **-9**
 Show a heat map of population fitness score distribution between generations.

## EXAMPLES

The following are some examples on how to use **pyevolve-graph**:
 1. Output a graph for identify 'ex1' in PNG format (default) to
 file 'graph\_ex1.png':

pyevolve-graph -i ex1 -1 -o graph\_ex1
 2. Output a graph for identify 'ex1' to the PDF file 'graph\_ex1.pdf':

pyevolve-graph -i ex1 -1 -o graph\_ex1 -e pdf
 3. This command will plot the evolution of the generations between 10 and 20:

pyevolve-graph -i ex1 -1 -g 10:20
 4. Use **-m** to indicate that you have minimized the evaulation function:

pyevolve\_graph.py -i ex1 -1 -m
 5. Specify an identify list for the comparison output options **-6** and
 **-7**:

pyevolve\_graph.py -i ex1\_run1,ex1\_run2,ex1\_run3 -6
 Fore more examples on how to use pyevolve-graph, including sample images, users
 are recommended to install the **python-pyevolve-doc** package.
