Matplotlib-based library for the creation of block diagrams. Besides this core functionality, blockplotlib provides a workflow to include all kinds of matplotlib figures with the correct font size into latex documents. While latex is also often used to render text inside figures/block diagrams, blockplotlib (as matplotlib) depends not on latex.
The functionality of the library is limited to the features demonstrated in the examples but can be extended quite easily.
How to draw a simple control loop is illustrated with the
example blockplotlib/examples/control_loop_one_dof.py.
A more complex example is the block diagram of the
so-called hyperbolic observer canonical form:
blockplotlib/examples/hyperbolic_ocf.py
The inclusion of matplotlib figures with the correct
font size into a latex document can be adapted
from the example under blockplotlib/examples/tex_article.
It basically relies on two measurements of the height of a string.
One measurement is performed in the latex preamble and the
other one in the respective matplotlib figure using
a blockplotlib function.
More examples can be found under blockplotlib/examples/.
One way to use blockplotlib is to install it via
pip (pip install blockplotlib).
Another way to use it is to copy the file blockplotlib.py in the folder
of the Python script from which it is to be imported.
