There are some discrepencies with the data at this time so drawing conclusions other than general usage patterns is advised against. Some issues include: entry/exit times that are the same or just one minute apart missing entry times
Currently it prints the following type of graph. The screenshot below treats all days as the same.
The parking-by-day script generates this graph for each day of the week. For images, check out the docs directory.
Python (tested with 2.7)
The data at http://data.grcity.us/dataset/parking-ramp-transactions saved as csv files
The lots.csv file (recently added to github)
The script will take a while to process as it's going over a large amount of data.
re-write all the card data conversions to be more useable. re-write display so that instead of ignoring data, it graphs a different line for that lot.
