# PlotMySpec
Small script to __plot fits spectra__ using Python and Matplotlib
## Requirements
```bash
pip install -r requirements.txt
```
## Quickstart
Customize your configuration file (pms.yaml).
__title_pattern, label_pattern and subtitle_pattern__ properties allow you to auto-fill value with your fits file header contents.
```bash
---
# ----------------------------------
# matplotlib general config
# ----------------------------------
line_width: 0.6
font_size: 9
title_font_size: 9
font_family: arial
math_font_family: custom
fig_size_x: 9
fig_size_y: 5
x_label: Wavelength in Å
y_label: Relative intensity
no_grid: 0
dpi: 150
# ----------------------------------
# spectrum config
# ----------------------------------
# object_name: auto-filled with keyword OBJNAME from header fits if empty
object_name:
title_pattern: "- %%DATE-OBS%% - %%EXPTIME2%% - %%OBSERVER%%"
label_pattern: "%%DATE-OBS%%"
subtitle_pattern: "%%BSS_INST%%"
spec_file_regex: '_(.+)_(\d+)_(\d+)(.*).fit'
# crop: allow to crop spectra (ex: "crop: 6500,6600,0,2" --> lambdamin,lambdamax,fluxmin,fluxmax )
crop: 0
# compare_mode : display all spectra on the same plot if active
compare_mode : 0
compare_mode_y_offset : 0
compare_mode_color_cycle: #red,black,yellow... or nothing for automatic mode
compare_mode_no_label: 0
# ----------------------------------
# display vertical lines
# ----------------------------------
lines_display_name: 1
lines_color: red
lines:
# line name, position in angstroms, offset x, offset y
- Hα,6562.82,6.,0.3
```
## Plot one or more spectra on distincts graphs
```bash
$ python pms.py /Volumes/Samsung_T5/2022-01-14/
- 🚀 PlotMySpec 1.1 - Start 🚀
- ✨ Load configuration file 🔧 pms.config.yaml
- 📁 4 spectra files found !

```
## Plot multiple spectra on the same graph
Set __compare_mode=1__ in your configuration file.
```bash
$ python pms.py /Volumes/Samsung_T5/2022-01-14/
- 🚀 PlotMySpec 1.1 - Start 🚀
- ✨ Load configuration file 🔧 /Volumes/Samsung_T5/ASTRO/Starex/mizar/pms.config.yaml
- 📁 7 spectra files found !
- 🖥 ✅ Process @m1.fits
