/**
|
|
* A final axis is translated and rotated from a "standard axis".
|
|
* So opt.position and opt.rotation is required.
|
|
*
|
|
* A standard axis is and axis from [0, 0] to [0, axisExtent[1]],
|
|
* for example: (0, 0) ------------> (0, 50)
|
|
*
|
|
* nameDirection or tickDirection or labelDirection is 1 means tick
|
|
* or label is below the standard axis, whereas is -1 means above
|
|
* the standard axis. labelOffset means offset between label and axis,
|
|
* which is useful when 'onZero', where axisLabel is in the grid and
|
|
* label in outside grid.
|
|
*
|
|
* Tips: like always,
|
|
* positive rotation represents anticlockwise, and negative rotation
|
|
* represents clockwise.
|
|
* The direction of position coordinate is the same as the direction
|
|
* of screen coordinate.
|
|
*
|
|
* Do not need to consider axis 'inverse', which is auto processed by
|
|
* axis extent.
