Course gallery

These are some of the charts that we create throughout the course.

An interactive legend (click to hide/show lines)

A dynamic legend (show data values in legend)

A custom tooltip (show items under the cursor)

Another custom tooltip, using the legend and highlighting lines

Using mplcursors to create a tooltip with extended data for a single point

Using a Slider widget to visualize with motion

Using a TextBox widget to search for a point in a scatter plot

Using a paginated chart to display many axes over several 'pages'.

This also lets you filter the data with a text box.

Show an axes as a tooltip on another axes.
