Classe: Image_Graph_Axis_Radar - X-Ref

Displays an 'X'-axis in a radar plot chart.

This axis maps the number of elements in the dataset to a angle (from 0-
360 degrees). Displaying the axis consist of drawing a number of lines from
center to the edge of the 'circle' than encloses the radar plot. The labels
are drawn on the 'ends' of these radial lines.

This is always 0

return: double The minumum value

_getMaximum() X-Ref

Gets the maximum value the axis will show.

This is always the number of labels passed to the constructor.

return: double The maximum value

_calcDelta() X-Ref

Calculate the delta value (the number of pixels representing one unit
on the axis)

return: double The label interval

_point($value) X-Ref

Get the pixel position represented by a value on the canvas

param: double $value the value to get the pixel-point for
return: double The pixel position along the axis

_size() X-Ref

Get the size in pixels of the axis.

For a radar plot this is always 0

return: int The size of the axis

setDistanceFromEnd($distance = 5) X-Ref

Sets the distance from the end of the category lines to the label.

param: int $distance The distance in pixels

_drawAxisLines() X-Ref

Draws axis lines.

_drawTick($value, $level = 1) X-Ref
