Here's an example of what I mean. Verizon reports my data usage as 1024 MB/month. This is clearly wrong because there's no way I use exactly 2^10 MB (or 1GB) every month. What's more, they report my allowance in MB as (2) when it's actually 2GB.
This table is wrong because:
- The data are wrong.
- The scales are wrong - not out of scale, but literally wrong.
- They have duplicated data (repeating total data used) for no clear reason.
- The alignment of the numbers is off - you put the ".00" on the right, so that people can compare big numbers by length.
- There's too much precision. Do I really need six significant digits on my data usage? No. Remove the decimals at least.
- All of the fonts are bold (save for the repeated data, which shouldn't be there) for no clear reason.
I'm not sure who's responsible for shipping this - but it clearly should never have been released. It's functionally broken and broken at a design level.
The Verizon Wireless Account Analysis chart is no better:
- The month label has exactly the same font treatment as the months - so it reads as "January month," rather than a label.
- Rather than putting the scale on the left, by Data (in MB) they put it in big bold font on the RHS.
- They put the title in a Tab, when there's clearly no other tab to select.
- They've left huge amounts of whitespace by putting the legend on the bottom instead of top right, like most legends. That's a nit, but still.
- Why is this weird window size like this, so that there's a huge gray border and also tons of whitespace beside the chart?
- Why did you capitalize megabytes? They are not a proper noun, they are a unit of measure, like inches.
Things like this make me want to short Verizon, but I think their fiber, wireless, and cable operations are better aligned than their competitors, so I suppose I have to forgive these painful mistakes.
