Reading data:

import mesaPlot as mp
m=mp.MESA()

Now m contains all the useful stuff

History files

m.loadHistory()

This loads up the history file data by default it will look for LOGS/history.data. But if you have a different folder to look at then you can either

m.log_fold='new_folder/LOGS/'
m.loadHistory()

or

m.loadHistory(f='new_folder/LOGS/')

Note this will automatically clean the history data of retries, backups and restarts. To write that data back to disk

m.scrubHistory()

Which will create a file "LOGS/history.data.scrubbed" if you don't want that then:

m.scrubHistory(fileOut='newFile')

Data can be accessed as m.hist.data['COLUMN_NAME'] or m.hist.COLUMN_NAME. The second option is also tab completable. The header information is either m.hist.head['COLUMN_NAME'] or m.hist.COLUMN_NAME.

Profile files

To load a profile file its:

m.loadProfile()

Again you change the LOGS folder either with log_fold or f=. To choose which file to load, either:

m.loadProfile(num=MODEL_NUMBER)
or
m.loadProfile(prof=PROFILE_NUMBER)

Where MODEL_NUMBER is a MESA model number and PROFILE_NUMBER is the number in the profile file name. You can also set a mode

m.loadProfile(num=MODEL_NUMBER,mode='first|lower|upper|nearest')

This is for when the model you want isn't in the data. Either we load the first model, the model just before the one you want, the model just after the one you want or the nearest (above or below) the model you want. There are also two special model numbers 0 for first model and a negative number that counts backwards (-1 is the last model, -2 is last but one etc)

Data can be accessed as m.prof.data['COLUMN_NAME'] or m.prof.COLUMN_NAME. The second option is also tab completable. The header information is either m.prof.head['COLUMN_NAME'] or m.prof.COLUMN_NAME.

Plotting

Here we'll show the basics of plotting, there are more complex examples for each section. Commands will assume you are in a MESA work folder, such that the data is in a LOGS/ folder.

History data

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadHistory()
p.plotHistory(m,xaxis='star_age',y1='log_center_T',y2='he_core_mass')

Profile data

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadProfile(num=-1)
p.plotProfile(m,xaxis='mass',y1='logT',y2='ye')

HR

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadHistory()
p.plotHR(m)

Kippenhan's

Kippenhan plot with model number vs mass. Note all Kippenhan plots require your history file to have both mixing_regions X and burning_regions Y set in your history_columns.list file, where X and Y are integers that specify the maximum number of mixing/burning zones in your model, values around 20 will usually suffice. Models going to core collapse may want to increase this limit to 40.

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadHistory()
p.plotKip(m,show_mass_loc=True)

Kippenhan plot with star age vs mass

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadHistory()
p.plotKip2(m)

Generic kippenhan plotter

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadHistory()
p.plotKip3(m,show_mass_loc=True)

New way of doing plotKip2 (star age vs mass)

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadHistory()
p.plotKip3(m,xaxis='star_age',age_lookback=True,age_log=True)

Profile based kippenhans

import mesaPlot as mp

m=mp.MESA()
m.loadHistory()
m.loadProfile(num=1)
p=mp.plot()
p.plotKip3(m,plot_type='profile',xaxis='model_number',yaxis='mass',zaxis='logRho',mod_min=1,mod_max=3000)

m.loadProfile(num=-1)
p.plotAbunByA(m)

import mesaPlot as mp
m=mp.MESA()

p.plotAbunByA(m,stable=True)

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
p.set_solar('ag89')

m2.loadprofile(num=-1)
#Plot the mass fractions relative to solar relative to 2nd model
p.plotAbunByA(m,m2=m2,stable=True)

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadHistory()
#Use the data in the history file at model_number==model
p.plotAbunByA(m,plot_type='history',model=1000,prefix='log_center_')

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
p.set_solar('ag89')
m.loadHistory()
#Use the data in the history file, plotting relative to another model number after decaying the isotopes to thier stable versions
p.plotAbunByA(m,plot_type='history',model=1000,model2=1,prefix='surface_',stable=True)

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadProfile(num=-1)
p.plotAbunPAndN(m)

import mesaPlot as mp

Burn data

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()
m.loadProfile(num=-1)
p.plotBurn(m)

import mesaPlot as mp
m=mp.MESA()
p=mp.plot()

Time series Profile plots

import mesaPlot as mp

m=mp.MESA()
m.loadHistory()
m.loadProfile(num=1)
p=mp.plot()
p.plotSliderProf(m,'plotAbun')

Passing in a string for the name of a plotting function, (only ones based on profile data). This will show that plot with a slider that can be used to iterate over the available profile files plotSliderProf will take any extra arguments passed to it and pass them to the plotting function.
