In this blog I would like to analyze a heatmap of “Daily Temperatures & Precipitation” of Sacramento from 1900 to 2015. The visualization consists of 3 separate charts in different tabs for high temperatures, low temperature and precipitation.
The first thing I really liked about this chart is tabs for different charts, labeling of axis is neat and not cramped & placement of legend.
I believe this chart is a perfect example of a heatmap.Even though every daily high/low temperature and precipitation is recorded in this chart, because the author choose a heatmap it does not look cramped. We can clearly see the changes of range of temperature not only along the season but also along the different years, we can clearly observe from the High temperatures chart that the High temperatures have been consistently increasing from 1900 to 2015. The high temperatures were highest only in the months of July – August in early 1900s to June – October in early 2000s.
The one thing I would change in the Daily High Temperatures chart as “Increasing temperature in Sacramento” . I believe that as per Tuesday’s class having a title which conveys a message/claim is better than having a description of the chart as the title.
In conclusion, I think this the heatmap is an excellent in its visualization of a 100 years of temperature.
