Many reasons for this, the biggest being the normative convention of a list. People gets confused and it makes them think about presentation rather than content. I agree with the correlating information, good for certain purposes, annoying for others. For example, it would be ideal if you wanted to show relationships or differences, left side for one variable, right side for the other variable and so forth.Rorschachhamster wrote:Well, WHY NOT? If you had a list with two correlating informations and put it on the left and right sides of the bullets, it could work quite well, maybe. I have to try that...JeX wrote:...
It's like showing a bulleted list: you wouldn't put information on both side of the bullets, would you?
But for the short range map I would prefer the one sided version, anyhow...
When the locations of the "bullets" do not have the same x-coordinates, i.e. on a chart or a map, I will argue that it gets confusing because you also have to think where the icons belong by drilling down into what color and representation it has.
Do try it out though and let us know how your audience found it
