* 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 |
* |
