What Sitting Looks Like
This week was about learning how to visualize the data I collected previously using two sensors. Armed with the data set from the previous week’s lab, I figured out how to parse both a .txt and a .csv file using the code supplied by Dan and some other code snippets from Visualizing Data.
When I tried last week’s assignment, I had started using an FSR by itself for about an hour before I got the GSR sensor working, and because the code appended the data from when I was using one sensor to the two sensor data set in the text file, I had some funky errors since there were added fields. Once I got that sorted, it was pretty straightforward to parse the data.
An interactive graph makes it easy to go through and view the data and compare two sensor sources, but to make this useful, I really need a third line that shows what I was doing during these different time periods. Otherwise, it doesn’t really reveal too much about the results. Also, while this is useful for general understanding of the sensors and visualizing the data set, it’s not terribly interesting for most people to scroll through. Just building this gave me a better sense of how I want to approach my next project. It really is important to start with a question and prepare how you want the data to be interacted with BEFORE you start.
