Module 09 Activity

Scenario

The charts are correct. Now make them reproducible and consistent across a whole deck.

What you build

A house-style function that every chart in your deck starts from, plus controlled axes, data-anchored annotations and deliberate exports.

Steps

1. Rewrite every chart to use fig, ax = plt.subplots() and work through ax. Remove any mixed plt. styling.
2. Set axis limits explicitly on every figure, with the floor at zero for bars.
3. Move every annotation and reference line to data coordinates. Resize one figure and confirm they stay put.
4. Write one house-style function that takes a title and a subtitle and returns a styled figure and axes.
5. Rebuild every chart in the deck through that function.
6. Export at three settings and check the result pasted into a slide, including bbox_inches='tight'.

Evidence to hand in

• The rewritten charts with no mixed styling.
• Explicit limits on every figure.
• The resize test for annotations.
• The house-style function.
• The deck rebuilt through it.
• The export comparison.

Review checklist

• No chart mixes plt. and ax. styling.
• Axis limits are set explicitly on every figure.
• Annotations survived a resize.
• Every chart in the deck comes from the one house-style function.
• Exports use bbox_inches='tight' and a resolution suited to the medium.
