Plot the trial graphs:
- mean_returns, strengths, sample_efficiencies, training_efficiencies, stabilities (with error bar)
- consistencies (no error bar)``````

# Cognitive Complexity

Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

### A method's cognitive complexity is based on a few simple rules:

• Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
• Code is considered more complex for each "break in the linear flow of the code"
• Code is considered more complex when "flow breaking structures are nested"

#### Ambiguous variable name 'l' Open

``        margin=go.layout.Margin(l=60, r=30, t=60, b=60),``

Never use the characters 'l', 'O', or 'I' as variable names.

``````In some fonts, these characters are indistinguishable from the numerals
one and zero. When tempted to use 'l', use 'L' instead.

Okay: L = 0
Okay: o = 123
Okay: i = 42
E741: l = 0
E741: O = 123
E741: I = 42

Variables can be bound in several other contexts, including class and
function definitions, 'global' and 'nonlocal' statements, exception
handlers, and 'with' statements.

Okay: except AttributeError as o:
Okay: with lock as L:
E741: except AttributeError as O:
E741: with lock as l:
E741: global I
E741: nonlocal l
E742: class I(object):
E743: def l(x):``````
