qpmg 0.2.2

Quick Plotting for MESA or GYRE

usage: qpmg [-h] [-x X [X ...]] [-y Y [Y ...]] [--xlabel XLABEL [XLABEL ...]]
            [--ylabel YLABEL [YLABEL ...]] [--legend LEGEND [LEGEND ...]]
            [--style STYLE] [--title TITLE [TITLE ...]]
            [--style-file STYLE_FILE]
            filenames [filenames ...]

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.

--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
