Plotting the exponential function¶
This example demonstrates how to import a local module and how images are
stacked when two plots are created in one code block. The variable N from
the example 'Local module' (file local_module.py) is imported in the code
below. Further, note that when there is only one code block in an example, the
output appears before the code block.
