In this lesson we looked at how to:
How to use .describe()
to quickly see some descriptive statistics at a glance.
How to use .resample()
to make a time-series data comparable to another by changing the periodicity.
How to work with matplotlib.dates
Locators to better style a timeline (e.g., an axis on a chart).
How to find the number of NaN values with .isna().values.sum()
How to change the resolution of a chart using the figure's dpi
How to create dashed '--'
and dotted '-.'
lines using linestyles
How to use different kinds of markers (e.g., 'o'
or '^'
) on charts.
Fine-tuning the styling of Matplotlib charts by using limits, labels, linewidth
and colours (both in the form of named colours and HEX codes).
Using .grid()
to help visually identify seasonality in a time series.
You can download the completed code for today in this lesson.
Well done for completing another challenging data science day! I hope working with Pandas is starting to feel more and more second nature at this point.
