Plots thermochronometer ages and closure temperatures

T_cplotter code description and instructions for use

T_cplotter is a Python package for creating and customizing thermochronometer age and closure temperature plots presented in the article Short communication: Modelling competing effects of cooling rate, grain size and radiation damage in low temperature thermochronometers by D. Whipp, D. Kellett, I. Coutand, and R. Ketcham. The code is designed to be easy to use to either reproduce plots from the article or customize the plots for your own use. Below you will find some essential details about using the code and detailed documentation can be found on the tcplotter documentation site.

Getting started

The easiest way to get started using T_cplotter is by using Binder either with the link here or by clicking on the Binder button above. This will open an interactive web interface to the code where you can see how it works and even create your own plots.

Installation

T_cplotter can be installed in your Python environment using pip.

pip install tcplotter

You can also find installation instructions on the T_cplotter documentation page.

Note: In order for T_cplotter to work properly you will also need to install the thermochronometer age prediction programs available in the T_ccore package.

Usage

T_cplotter can be used either as a function in a Python script or interpreter, or from the command line. The four main T_cplotter functions/command-line tools are:

• time_vs_temp()
• eu_vs_radius()
• rate_vs_radius_eu()
• rate_vs_age_tc()

Brief examples of possible usage for both cases can be found below.

Usage in a Python script or interpreter

Assuming you are working in Binder or have installed tcplotter locally, functions available in T_cplotter can be imported as follows:

from tcplotter import time_vs_temp, eu_vs_radius, rate_vs_radius_eu, rate_vs_age_tc

Once imported, you can use functions as shown below:

eu_versus_radius(save_plot=True)

You can find more information about the function parameters using the help() function:

help(eu_vs_radius)

Command-line usage

Command-line usage is similar to that for use in a Python script, except that the underscores in the function names have been replaced by hyphens. For example, again assuming you have installed tcplotter locally, you can type the following to use the eu_vs_radius() function:

eu-vs-radius --save-plot

To find more information about options available for command-line use you can include the --help or -h flags.

eu-vs-radius -h
