Annotated Line Graph – Power Consumption

Power Consumption Data Visualization

Cole Knaflic, the ​author of Storytelling with Data, one of my favorite data visualization books in recent times, runs a challenge every month on presenting any form of data in a specific chart type. This past month, the challenge was for an annotated line graph. I submitted the above entry [click here for enlarged version] using the daily power consumption data I download from Austin Energy.

The data are a bit erratic and specific data points are not that reliable but I think the overall trend lines are somewhat symptomatic of our usage especially after we did an extensive overhaul of our roof attic insulation and fixed the AC duct pipes.
