Plotting API

Packages

The flow of execution for plotting XY-type data in relax is:

• The user function definition in the user_functions.grace module (in the future the user_functions.plotting module).
• The pipe_control.plotting.write_xy() function.
• The lib.plotting functions write_xy_header() and write_xy_data().

Package: user_functions

The user interface for plotting are generally the user functions. Currently this consists of the grace.write and dx.map user functions. However in the future a software independent interface will be gradually implemented via a new plotting user function class. An idea would be to have one user function per graph type, for example:

• plotting.write_2D
• plotting.write_iso3D
• plotting.write_2D_fitted_curves

Package: pipe_control

To use the backend code, you need to import:

from pipe_control.plotting import write_xy
