pb-simple-waffle-chart

This component can be used to create simple waffle charts. The color or background image of a category can be customized. The area of the entire waffle chart and of the single waffle must be defined. The real numbers of every category are the inputs. No need for a pre-processing. The component calculates the ratio for every category and displays the results optimally. It must be ensured that the defined size of a waffle fits into the defined size of the entire waffle chart.

Install

You can get it on npm.

npm i pb-simple-waffle-chart --save
