Why your Windows PC gets slower over time

Many users blame this on aging hardware, the unavoidable decay of technology over time and in some ways it is, leading some to give up. However, the truth is much more subtle and fixable.

Stop using pie charts in Excel: build this dynamic bar chart instead

You’ve finalized your Excel spreadsheet and want to visualize your numbers. A pie chart is a tempting option: it takes 20 seconds to create and makes you look sophisticated. However, it often causes more confusion than it solves. To truly impress your coworkers and make your data pop, ditch the circle and build a bar chart that updates itself.

Once you move past three or four slices, pie charts become unreadable, often requiring messy legends and manual labels that clutter the screen. More importantly, even if you sort the underlying data feeding a pie chart, the circular format makes the hierarchy difficult to follow—leaving your visuals in a jumbled mess. By taking the hallmarks of a pie chart and applying them to a dynamic bar chart, you solve all these problems—no legends, no clunky labels, and no confusing order.
