| * Right, this is really confusing and there is a lot of maths going on here |
| * The gist of the problem is here: https://gist.github.com/nnnick/696cc9c55f4b0beb8fe9 |
| * |
| * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif |
| * |
| * Solution: |
| * |
| * We assume the radius of the polygon is half the size of the canvas at first |
| * at each index we check if the text overlaps. |
| * |
| * Where it does, we store that angle and that index. |
| * |
| * After finding the largest index and angle we calculate how much we need to remove |
| * from the shape radius to move the point inwards by that x. |
| * |
| * We average the left and right distances to get the maximum shape radius that can fit in the box |
| * along with labels. |
| * |
| * Once we have that, we can find the centre point for the chart, by taking the x text protrusion |
| * on each side, removing that from the size, halving it and adding the left x protrusion width. |
| * |
| * This will mean we have a shape fitted to the canvas, as large as it can be with the labels |
| * and position it in the most space efficient manner |
