Mainly I don't like that the pie charts are hard to tell what is what. If there are 6 or 7 things and you have to tell which is which by colour, that's a bit tricky. Labels on the sections would be better, but I haven't worked out how to do that.

Maybe if I think a pie chart shows it best, I'll also include the bar chart so it's clearer.

Use a bar chart. Pie charts are for marketing and pizza.

Also, no one cares if a bar chart sums to more than 100% ;-)

I dunno. I feel something like this works better as a pie chart.

Pie charts tend to work when you have three to four categories, more than that they fall apart.

The nice thing about the bar chart is the axis label which can be the raw value rather than a percentage, having a large (7-8) number of categories is still readable especially if there minority categories.

Also, is all just my opinion, so don't let me stop you using whatever you like!

I think pie charts are also helpful for when you have 10 categories but two of them make up 90% of the result.

But your bar chart preference is noted, so I'll try to make sure to include them along side pie charts 🙂

Poor data visualisation is a pet peeve of mine and I'm disproportionately vigorous when talking about it ;-)

Especially after a few drinks with dinner.

Haha one of my pet peves for data visualisation is graphs that don't start at zero. I get sometimes the movement is too small to visualise properly when you start from zero, but you can't probably understand the scale if you don't start at zero.

I bet you'll argue with me on that!
