Time series data is data that is recorded. Visualizing this type of data helps clarify trends and illuminates relationships between data.

Plotting time-series data

Read data with a time index

Plot time-series data

Using a time index to zoom in

Plotting time-series with different variables

Plotting two variables

Defining a function that plots time-series data

Using a plotting function

Annotating time-series data

Annotating a plot of time-series data

Plotting time-series: putting it all together

Visualizations can be used to compare data in a quantitative manner. This chapter explains several methods for quantitative visualizations.

Quantitative comparisons: bar-charts

Bar chart

Stacked bar chart

Quantitative comparisons: histograms

Creating histograms

"Step" histogram

Statistical plotting

Adding error-bars to a bar chart

Adding error-bars to a plot

Creating boxplots

Quantitative comparisons: scatter plots

Simple scatter plot

Encoding time by color

Quantitative comparisons and statistical visualizations

This chapter shows you how to share your visualizations with others: how to save your figures as files, how to adjust their look and feel, and how to automate their creation based on input data.

Preparing your figures to share with others

Selecting a style for printing

Switching between styles

Saving your visualizations

Saving a file several times

Save a figure with different sizes

Automating figures from data

Unique values of a column

Automate your visualization

Where to go next

Visualizing data in plots and figures exposes the underlying patterns in the data and provides insights. Good visualizations also help you communicate your data to others, and are useful to data analysts and other consumers of the data. In this course, you will learn how to use Matplotlib, a powerful Python data visualization library. Matplotlib provides the building blocks to create rich visualizations of many different kinds of datasets. You will learn how to create visualizations for different kinds of data and how to customize, automate, and share these visualizations.
