|
||||
*
|
||||
* 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
