Polar Scaffolds

Abstract

In the last chapter, you learned how to use horizontal and vertical line scaffolds to lay out the glyphs in your chart as an alternative to sub-layouts. We also concluded that their use was limited to a few specific chart designs. However, there is another type of scaffold that does provide us with a wealth of design options. If you want to design circular types of chart such as pies, donuts, or radar charts, you will need to apply the polar scaffold, and, unlike horizontal and vertical line scaffolds, with this scaffold you’re supplied with a comprehensive choice of sub-layouts to work with. In this chapter, you will learn how to use the polar scaffold to generate not only conventional circular charts, such as the pie chart, but also more unusual and interesting ones too. We will also take a look at the custom curve scaffold which includes a tool for generating spiral and wavy style charts.
