Comparison
| Element | Poor Graphic | Worked Graphic |
|---|---|---|
| legend | The legend is inconsistent in its symbols and in its ranges (not continuous). | The symbols are continuous and follow the rules for representing non-metric but ordinary classes of ranges [1][Miksch, 2005] Moreover the ranges which are represented by the symbols were made to descend into one another. |
| legend (symbols) | The root version, even though its symbols are inconsitent in shape and color, gives a rough impression where snow can be expected in a major amount. It provides the user with some sort of a rough overview about Idaho and the snowfall. This is information we thought is very useful. | The symbols now give a good impression where high amounts of snowfall can be expected. Not only through the symbol size, but also through the symbol and its viasual density we rose the differentiation of the classes. |
| legend (background) | The legend has no explicit bakground. | The background of the legend is in white, keeping it seperated from the grey overall bacground and maximizing the contrast to the symbols and the text in the legend. |
| background (map, the image) | Keeps no information (for the data of snowfall) | Was exchanged by a satellite view of Idaho, giving just the outer bounds of the state and the inner borders of the different districts. |
| background (radial gradient) | Is distracting the viewer, keeps no additional information. | Was changed to a very light gray background to keep a contrast between the shape of the land (which is white in large parts as well). |
| spot indicators (color) | The spot indicators are all of a different color, which can not at all be related to the amount of snow it should represent. | The color keeps no informations, so the attribute is dumped. |
| spot indicators (form) | Are inconsistent and the fourth one does not give a good idea where the center actually is (asymetric). | The new symbol has a clear center point, representing the spot on the map where the viewer can expect the place named. |
| spot description (text) | The text is in white, which has a too low contrast most of the time due to the irregular color of the background image. | The text is written in simple black color. |
