Time Series Graphs

Today I worked through Chapter 4 of Visualizing Data, titled "Time Series." In this Chapter, we got into the actual mechanics of creating a solid graph, in that in contains all of the necessary components to clearly illustrate the data. Half of the chapter covered nitty-gritty details, such as axis labels, tick marks on the axis, or small lines on the graph to give the viewer a sense of scale.

In addition, the chapter covered various methods of actually presenting the data in question: a series of points, a series of line segments, a smoothed line, a combination of points and lines, a solid-color area, or a bar graph.



We even added in a mouseover function to display the value of data points when moused over.


The original graphs were drawing from a table of three different subjects; Coffee, Tea, and Milk. Originally the user was able to access the different graphs by scrolling through via the "[" and "]" keys, but in the final exercise we added tabs up top that responded to the user's mouse clicks.
