Visualization of Temporal Data
In temporal data visualization, time is the independent variable and the other features that are being visualized are plotted against time. So, the other features are dependent variables. Usually, time is plotted on the x axis, while the dependent variables are plotted on the y axis. We can see a few plots here:
- Line graph:
Figure 5.5: Line plot representing temporal data
This line graph shows the percentage change in the population of a country for each year. If multiple lines are plotted on the same graph, then it gives us a comparative study of the features. Lines plots are easy to interpret and also simple to plot.
- Grouped bar chart:
Figure 5.6: Grouped bar plot representing temporal data
This grouped bar chart shows the counts of medals (shown on the y axis) received in 2012, 2014, and 2016. Having many lines on the same line graph plot makes visibility and comparability poor...
