shuffle_colorbar

Context: images

Synopsis

Shuffles the rendering order of the colorbar within the depth.

Syntax

shuffle_colorbar()
shuffle_colorbar(direction)
shuffle_colorbar(id)
shuffle_colorbar(id, direction)

Description

The function arguments.

Argument Description
direction What direction should the object be shuffled? The options are: chips_forward, chips_backward, chips_front, and chips_back. The default value is chips_forward.
id A ChipsId structure identifying the item, or a string containing the name of the object.

The shuffle_colorbar command modifies the location of the specified colorbar within the stack of items at the same depth. It may be used to position a colorbar in front of or behind other objects which are at the same depth.

Example 1

chips> add_colorbar(0.5, -0.05)
chips> shuffle_colorbar(chips_back)

Create a colorbar, then move it to the back of the stack.

Example 2

chips> shuffle_colorbar("cbar2", chips_front)

Move the colorbar "cbar2" to the front of the depth.

Shuffling objects

By default, objects within a depth are ordered chonologically based on when they were added to that depth. The objects are stacked with the oldest item at the back of the list and the newest item at the front of the list. This order dictates how the objects overlap when drawn.

The shuffle command changes the object's position within the stack. Any given object may be shuffled forward or backward one place in the stack or sent directly to the front or back of the stack.

The direction options:

Value Description
chips_back Send to the back of the stack.
chips_front Send to the front of the stack.
chips_forward Move one step closer to the front of the stack.
chips_backward Move one step further back along the stack.

The shuffle routines can only operate on a single object. An error is returned if currency is set to "all".
