|
|
|
- * 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

|
|
|
+ * 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
