Mediaan van de levensverwachting

In de volgende oefening maak je een cumulatieve tijdreeks van de mediane huizenprijsindex per regio. Om dat te kunnen doen, moet je eerst de mediane huizenprijsindex per jaar voor elke regio berekenen.

Gebruik het dplyr-pakket om deze taak uit te voeren.

A review of key plotly commands. You will review how to create multiple plot types in plotly and how to polish your charts. Additionally, you will create static versions of the bubble and line charts that you will animate in the next chapter.

Exercise 1: Interactive and dynamic graphics Exercise 2: Which is the interactive graphic?Exercise 3: A simple time series plot Exercise 4: A simple scatterplot Exercise 5: Adding aesthetics to represent a variable Exercise 6: Color and size Exercise 7: Plotting symbols Exercise 8: Polishing your graphics Exercise 9: Moving Beyond Simple Interactivity Exercise 10: Bubble charts Exercise 11: Many time series

In this chapter, you will learn how to implement keyframe animation in plotly. You will explore how to create animations, such as Hans Rosling's bubble charts, as well as cumulative animations, such as an animation of a stock's valuation over time.

Exercise 1: Introductie tot geanimeerde graphics Exercise 2: Wat is de frame?Exercise 3: Waarom hebben we ids nodig?Exercise 4: Een scatterplot animeren Exercise 5: Factors als frames Exercise 6: Animaties verfijnen Exercise 7: Je regionale animatie verfijnen Exercise 8: Je HPI-animatie verfijnen Exercise 9: Lagen gebruiken in plotly Exercise 10: Achtergrondtekst toevoegen Exercise 11: De basislijn plotten Exercise 12: Cumulatieve animaties Exercise 13: Hoeveel rijen?Exercise 14: Mediaan van de levensverwachting

When you are exploring unexpected structure in your graphics, it's useful to have selections made on one chart update the other. For example, if you are exploring clusters observed on a scatterplot, it is useful to have the selected cluster update some chart of group membership, such as a jittered scatterplot or sets of bar charts. In this chapter, you will learn how to link your plotly charts to enable linked brushing. Along the way, you will also learn how to add dropdown menus, checkboxes, and sliders to your plotly charts, without the need for Shiny.

In the final chapter, you will use your expanded plotly toolkit to explore orbital space launches between 1957 and 2018. Along the way, you'll learn how to wrangle data to enable cumulative animations without common starting points, and hone your understanding of the crosstalk package.
