I’m doing some form of data visualization learning for 180 days because I need to #JFDI. See post explaining how and why I’m doing this.
Module Four Scales Review
- Commented more code to review. Realizing how little I knew before but how much more memory recall I’m having with the functions.
Reading and Learning Data Visualization Theoretically/Critically:
Reading Nathan Yau’s book Data Points – Visualization that Means Something
p. 151-165 Visualizing Time Series Data
- Some easy ways to visualize time series using “length, direction, and position” p 155
- Bar graph
- Line chart
- Dot Plot
- Dot-bar graph
- Radial Plot
- Calendar “heatmaps”
- “LOESS (or LOWESS) stands for locally weighted scatterplot smoothing…. which fits a polynomial function to a subset of the data at different points. When combined, they form a continuous line.” p 158
- Put together time series data in a way that can show cycles, different views to explore maybe needed for understanding, eg seeing dips in travel on a radial chart some days of the year, but looking at a calendar heatmap to see how holidays are what’s causing them p. 164
