Extends mxGraphLayout to implement a radial tree algorithm. This layout is suitable for graphs that have no cycles (trees). Vertices that are not connected to the tree will be ignored by this layout.
var layout = new mxRadialTreeLayout(graph); layout.execute(graph.getDefaultParent());
| mxRadialTreeLayout | Extends mxGraphLayout to implement a radial tree algorithm. |
| Functions | |
| mxRadialTreeLayout | Constructs a new radial tree layout for the specified graph |
| Variables | |
| angleOffset | The initial offset to compute the angle position. |
| rootx | The X co-ordinate of the root cell |
| rooty | The Y co-ordinate of the root cell |
| levelDistance | Holds the levelDistance. |
| nodeDistance | Holds the nodeDistance. |
| autoRadius | Specifies if the radios should be computed automatically |

| rowMinX | Array of leftmost x coordinate of each row |
| rowMaxX | Array of rightmost x coordinate of each row |
| rowMinCenX | Array of x coordinate of leftmost vertex of each row |
| rowMaxCenX | Array of x coordinate of rightmost vertex of each row |
| rowRadi | Array of y deltas of each row behind root vertex, also the radius in the tree |
| row | Array of vertices on each row |
| Functions | |
| isVertexIgnored | Returns a boolean indicating if the given mxCell should be ignored as a vertex. |

| calcRowDims | Recursive function to calculate the dimensions of each row |
mxRadialTreeLayout.prototype.execute = function( parent, root )
Implements mxGraphLayout.execute.
If the parent has any connected edges, then it is used as the root of the tree. Else, mxGraph.findTreeRoots will be used to find a suitable root node within the set of children of the given parent.
| parent | mxCell whose children should be laid out. |
| root | Optional mxCell that will be used as the root of the tree. |
