Randall tells graphic designers they can be more space-efficient by using ''hue'' (an element of color) and the data point's ''label'' in their graphs to represent the first two quantitative dimensions of a dataset rather than what's traditional: using x and y axes and then using hue and label to represent additional dimensions (such as hue for the z-axis, or the label for qualitative info). | Randall tells graphic designers they can be more space-efficient by using ''hue'' (an element of color) and the data point's ''label'' in their graphs to represent the first two quantitative dimensions of a dataset rather than what's traditional: using x and y axes and then using hue and label to represent additional dimensions (such as hue for the z-axis, or the label for qualitative info). | ||
β | In this comic's hue-label graph, the x-axis dimension is (mostly) translated into corresponding hue values, and the y-axis dimension is translated into text labels; that is, the mass of colorful lines in the comic is actually [https://www.explainxkcd.com/wiki/images/4/4a/compact_graphs_2x.png several numbers written in the same spot]. Each number is one of the y-coordinates of a point in the left graph, and its color (usually) corresponds to its x-coordinate using the Hue, Saturation, Value (HSV) model. In other words, the labels' colors are not arbitrary; each color represents a numerical dimension of the data point as a Hue value from 0 to | + | In this comic's hue-label graph, the x-axis dimension is (mostly) translated into corresponding hue values, and the y-axis dimension is translated into text labels; that is, the mass of colorful lines in the comic is actually [https://www.explainxkcd.com/wiki/images/4/4a/compact_graphs_2x.png several numbers written in the same spot].
