In the meantime, we will introduce data plotting in Python and Pandas. The basic workflow for the early stages of exploratory data Build a DataFrame from the data (ideally, put all data in this object) Clean the DataFrame. It should have the following properties: Deal with missing data Each...
One convenience provided, for example, is that if the DataFrame’s Index consists of dates, gcf().autofmt_xdate() is called internally by pandas to get the current Figure and nicely auto-format the x-axis. In turn, remember that plt.plot() (the state-based approach) is implicitly aware...
matplotlib is a desktop plotting package designed for creating plots and figures suitable for publication. The project was started by John Hunter in 2002 to enable a MATLAB-like plotting interface in Python. The matplotlib and IPython communities have collaborated to simplify interactive plotting from ...

Let’s bring one more Python package into the mix. Seaborn has adisplot()function that plots the histogram and KDE for a univariate distribution in one step. Using the NumPy arraydfrom ealier: Python importseabornassnssns.set_style('darkgrid')sns.distplot(d) ...
In this lecture, we will summarize on the cleanness of IMDb data. Then we will introduce data visualization and data merge in Python and Pandas. The basic workflow for the early stages of exploratory data Build a DataFrame from the data (ideally, put all data in this object) ...
Note that our function could take a pandas dataframe or series quite easily, but just to keep things as simple as possible I’ll stick to plain numpy arrays. To see how to use pandas datatypes with PyXLL see the pandas examples on github:https://github.com/pyxll/pyxll-examples/tree/mas...
