Info¶
Widgets
Use the %%interact expr0;expr1;... cell magic to set widgets for that cell.
Each expression is of the form x=y, where x becomes the local var of the cell and y can be a:
listto indicate choices for a dropdown widgettupleto indicate values for an int slider (start, stop, and optional step).
E.g.:
%%interact column=list(df.columns)
%%interact column=list(df.columns);mult=[1, 2, 3]
%%interact column=list(df.columns);window=(10, 50)
%%interact column=list(df.columns);window=(10, 50, 5)
Table of Contents
Use the %toc line magic to substitute with a table of contents in static mode.
Toggles
Click the Toggle input cells button at the bottom to reveal input cells.
Data¶
Using randomly generated data (with fixed seed).
In [6]:
df = pd.DataFrame(
np.random.RandomState(42).rand(100, 10), columns=list("abcdefghij")
)
Visualization¶
Simple¶
In [7]:
%%interact column=list(df.columns);mult=[1, 2, 3]
title = f"column={column!r}, mult={mult}"
(df[[column]] * mult).plot(figsize=(15, 8), lw=2, title=title)
Out[7]:
mult:
In [8]:
%%interact column=list(df.columns);window=(10, 50, 5)
ax = (
df[[column]]
.iloc[-window:]
.plot(figsize=(15, 8), lw=2, title=f"column={column!r}, window={window}")
)
ax
