qpmg

usage: qpmg [-h] filenames [filenames ...]
            [-x X [X ...]] [-y Y [Y ...]] [--xlabel XLABEL [XLABEL ...]]
            [--ylabel YLABEL [YLABEL ...]] [--legend LEGEND [LEGEND ...]]
            [-s STYLE] [--scale-x SCALE_X] [--scale-y SCALE_Y] [--flip-x]
            [--flip-y] [--plotter {plot,semilogx,semilogy,loglog}]
            [--title TITLE [TITLE ...]] [--style-file STYLE_FILE]
            [--rcParams RCPARAMS [RCPARAMS ...]]

qpmg is a simple Python script to quickly inspect output that adheres to the format used by MESA's profiles and histories and GYRE's summaries and mode files. While qpmg provides some options, it's intended for quick inspection rather than publication-quality plots. To see the list of available columns in a file, run qpmg on a given file. The defaults will cause an error that displays the available columns.

positional arguments: filenames

optional arguments:

-h, --help show this help message and exit
-x X, -y Y Column(s) to use for the x and y variables. The code loops through however many x and y keys you give (inner loop over x, outer loop over y) but most of the time you probably only want one x variable.
--xlabel XLABEL, --ylabel YLABEL
 Overrides the axis label with the given string. Accepts spaces. i.e. 'effective temperature' is OK. Default is to use the first argument of -x/-y.
--legend LABELS
 If auto, add a legend using the filenames as keys. Otherwise, use the arguments as a list of keys. Default is no legend.
-s STYLE, --style STYLE
 point style, passed to plot function (default=-)
--scale-x SCALE_X
 multiply variables on x-axis by this much (default=1)
--scale-y SCALE_Y
 multiply variables on y-axis by this much (default=1)
--flip-x reverse the x-axis
--flip-y reverse the y-axis
--plotter PLOTTER
 use matplotlib.pyplot.PLOTTER to plot (one of plot, semilogx, semilogy or loglog, default=plot)
--title TITLE Adds the given title to the plot. Accepts spaces. i.e. my plot is OK. Default is no title.
--style-file STYLE_FILE
 Specifies a matplotlib style file to load.

Installation

qpmg is available through pip:

pip install qpmg

You can also clone this GitHub repo:

git clone https://github.com/warrickball/qpmg.git
cd qpmg
pip install -e .

or similar.

Finally, the program is entirely constrained in the script qpmg, so you can download this one file and use it as you please. For example, I keep $HOME/.local/bin in my $PATH variable, so I might get the latest version of the script with

wget https://raw.githubusercontent.com/warrickball/qpmg/master/qpmg -O $HOME/.local/bin

Examples

Here are a few examples from the output of MESA's test suite (r10398).
