Join Ray Villalobos for an in-depth discussion in this video Using ordinal scales, part of Data Visualization with D3.js.
…In the last video, we took a look at quantitative skills, and…now we need to look at something else called an ordinal scale.…An ordinal scale lets you map a series of values that have a meaningful order.…So whereas before we were concerned with the value of the data, so the numbers here…were what we wanted to re-map so that they fit the height of this chart.…What we're interested now is we're dealing with the actual position of these elements…so they remap horizontally to fit the allotted room for this chart.…
So the problem that we're having now is if we keep on adding values,…eventually we're going to get to the right side and they're going to sort of go off.…So we need to fix that so that no matter how many values we enter,…the width of everything will fit according to the size that we have.…In order to do that we'll need to work with ordinal scales and…you can read more about them at this url.…And as you can see when you scroll down the ordinal scales are really…about repositioning.…Existing values the order of some data.…
