[MUSIC] So there's some things with charts that you should and shouldn't do. These are the shouldn't dos, the no-nos. Speaking of pie charts, on the very left side, you see that there's just so many slices there almost all identical. Your eye and your mind cannot see the differences, so it's really no point. Perspective, it's really groovy and cool. Everybody wants perspective pie charts and pie charts now, don't do that because it distorts the data. It becomes nothing more than decorative. The next one over, not enough elements, it's plotting 48 and 52. You don't really need a pie chart, these things are vehicles so that people can make meaning of the data and can understand it more. This is just purely decorative, there's no reason to make a pie chart for that. And then the last one, there are just so many elements. You want to keep your elements down to about seven, five, six, seven elements, no more. This chart is really good for pointing out some things that you should be aware of. Once again it's in perspective, it's distorting the numbers in the back compared to the front. But start up at the top, Student Government 2005-2006 Allocation. That would be better said as Student Government Allocation, 2005-2006. The next thing is the $65,000, that the numbers on this chart, don't really at up to 65,000. So, you want to check your math. For some reasons there some extra wedge in between every single one of these slices. So it adds to the visual noise of the graphic. And I don't even know how you do that in a graphic. Well you'll notice that the lower left is 3,500. The upper right is 7,400. If I doubled that, and more than double. And it's sort of like, they look like they're exactly the same size. That's probably the proportion thing. But if you look at the next one, 8000 next to 3500, it feels like these are very not really plotted even correctly. And lastly, this groovy, this is supposed to be like a coin shaped thing. And I think this is the shadow. So they put the SGA into the shadow. To make it like groovy and cool, like SGA I'm in the shadow. You know, don't do that. That's just gimmicky, crummy stuff. I had a student sort of redesign this, and even this one has problems. The type off to the left for the other category is crippling. The other category is crippling, there's just so much data there. And you'll notice that there are comma's in some of the numbers like on the right there habitat for humanity has 7,400 but right below it, diversity services it's 4,000 but it doesn't have comma. You want to make sure you're consistent. This person didn't add this things up so it still says 65,000. But you know, maybe this should be broken into two different pie charts. Instead of having that massive other category, find other ways to work with this data. With bar charts, don't ever do 3D. It just means nothing, it's purely decorative. Everybody loves them, but you don't know where to read the data point. You can see the yellow lines I have there. It really is hard for the human eye to figure out what you're trying to say. And again on the right, two bars is often not enough, a lot of people use those just to have a visual vehicle on the page, something, some visual element, so they'll plot two bars side by side and it's really not enough to show any kind of a trend really. Although it's not wrong to do it, it's just not really necessary. Zero basing is the big question, to zero base or not to zero base. Well, if you look at these two charts, you'll see that the one on the left looks like it's a slower rising trend than the one on the right, which is zooming up. What's going on here is the one on the right has a starts off at the bottom at 40, and the one on the left starts off at 0. There are purists of course who say that all charts have to start at zero. You have to zero base all charts. But sometimes, it's hard to read the data, and their argument for not doing it is that, you can't really read the data at the very top. In this case you can, but some of them, it's just a flat line, so they zoom in on the top. I actually don't have a problem with that. Please don't send me any emails. Just disagree with me. But if its a clearly delineated, indicated scale, I don't have a problem with that. And in particular, never do this. A lot of people think that, you can put categories below a line chart. Like you're showing airline profits and you're showing Delta and United, and you're connecting a line between them. In this case it's fruit. Really, it's got to be over time on a line chart. Basically, there are some very rare exceptions, but it's a flowing thing over time. You could show one price of fruit, like kiwi, over time. For example, in this particular case. Apples didn't go up to pears, which plunged down to grapes and kiwis. It's, they were not connected in any way. A line chart is just for showing over time, not categories. Just don't do it, and you'll be fine. Also, try to avoid. Being cliche colors. These are colored because they're the color of the fruit. You get it, wink, wink. Apples are red, bananas are yellow, so I made all of the bars this color. It's stupid and it makes people think that this color has information. Just make it a straightforward bar chart. And don't outline things in black, it looks really cartoony. Just try never to outline anything in anything, if you can avoid it, unless that's your style. Like your children's book and you've got this outline thing going on. But outlines tend to sort of feel like, you need to outline something because the design isn't working. So you've gotta outline it to make it pop from the background or something. And that's just not necessary. Let the colors hold their space. In this case, this person thought that the data isn't interesting enough. I have this sort of theory that if you think data isn't interesting, then you're going to do all these like tap dancing, top hat and cane tricks to try to get people to look at the data. And they're coming to the data, because they're interested in the data. You don't have to draw like rainbow color bars like in this particular case, just keep it simple and elegant and it will reflect well on whatever your company is, or your organization, or on you.
