Edward Tufte Graphics - Essay Example In addition he insists that an excellent graphic should be one that is multivariate. Eventually, he insists that an excellent graphic should speak nothing but the truth (Tufte’s principles 2009). Hence, any good graphic should exhibit these. In relation to principles of graphical integrity, Tufte insists that it has to be detailed and clear. He advises that the graphic has to be thoroughly labeled and should be able to show data variation. He adds that the graphic should not quote any data out of the context. Furthermore, the principle warns of exceeding the dimensions of data depicted by the graphic (Darzynkiewicz, Robinson & Roederer 2009, p. 45). Hence, graphic integrity is a very useful tool graphic representation. Concerning the principles of data graphics, Tufte insists that any graphic information should above all things show the data. He insists that the data-ink ratio should be maximized in the graphic (Darzynkiewicz, Robinson & Roederer 2009, p. 45). Data-ink ratio i s simply the core of a graphic that cannot be erased. It could also imply data ink divided by the total ink that was used to print the graphic. It is basically the arrangement of non-redundant ink in relation to variation in the presented numbers (Darzynkiewicz, Robinson & Roederer 2009, p. 45). ... Tufte insisted that people should forgo chartjunk, including the grid, the duck and moire vibration (Liere, Adriaansen & Elena 2009, p. 6). For any good graphic, details of no importance should not be included. Tufte also came up with the principle of erasing and data-ink maximization so as to be applied in some graphical designs (Liere, Adriaansen & Elena 2009, p. 6). He insisted that if these principles were applied on the scatter plot and the box plot among others, new designs would be created. He insisted that for the scatter plot, one could edit the frame lines in order to display the minimum, maximum, median and the two quartiles for both variables (Liere, Adriaansen & Elena 2009, p. 6). In relation to the principle of multi-functioning graphical elements, Tufte insists that any graphical element is one that carries data information plus performs design functions left to non data ink. In following this principle, one is able to display several pieces of data at the same time in one graphic (Mizuno & Sheldon 2012). The principle basically mobilizes every graphical element sometimes several times in order to depict or show data. The graphical element that plots or locates or plots data is referred to as the data measure (Mizuno & Sheldon 2012). One can build data measures from data though it will increase the dimensionality of the graphic plus the quantitative details. He adds that varying shades of grey depict varying quantities in a better way than color, since they possess a natural visual hierarchy. In addition, graphical information can be organized for different aspects of data at different visual angles. Also, Tufte insists that for the
