Class: ScaleViewController

ScaleViewController(uiState, container, decompViewDict) → {ScaleViewController}

ScaleViewController

Alters the scale of points displayed on the screen.

Constructor

new ScaleViewController(uiState, container, decompViewDict) → {ScaleViewController}

Parameters:
Name Type Description
uiState UIState

The shared state
container Node

Container node to create the controller in.
decompViewDict Object

This object is keyed by unique identifiers and the values are DecompositionView objects referring to a set of objects presented on screen. This dictionary will usually be shared by all the tabs in the application. This argument is passed by reference. Note that only the decompositions of type 'scatter' will be controlled, other types will be ignored.

Methods

decompositionName()

Get the name of the decomposition selected in the metadata menu.

Inherited From:
Source:

forceRefresh()

Writes the current settings to the active decomposition view(s). Will be called when the decomposition view is swapped out for a different view type.

Inherited From:
Source:

fromJSON(Parsed)

Decodes JSON string and modifies its own instance variables accordingly.

Parameters:
Name Type Description
Parsed Object

JSON string representation of self.
Inherited From:
Source:

getMetadataField()

Get the name of the selected category in the metadata menu.

Inherited From:
Source:

getScale(values, scaled)

Helper function to get the scale for each metadata value

Parameters:
Name Type Description
values Array.<String>

The values to get scale for
scaled Boolean

Whether or not to scale by values or just reset to standard scale (1.0)
Inherited From:
Source:
Throws:

No or one numeric value in category and trying to scale by value

Type
Error

getSlickGridDataset() → {Array}

Retrieves the underlying data in the slick grid

Inherited From:
Source:
Returns:

Returns an array of objects displayed by the body grid.

Type
Array

getView()

Get the view that's currently selected by the metadata menu.

Inherited From:
Source:

hasMetadataField(m) → {Bool}

Check if a metadata field is present

Parameters:
Name Type Description
m String

Metadata column to check if is present.
Inherited From:
Source:
Returns:

Whether or not the metadata field is present.

Type
Bool

refreshMetadata()

Update the metadata selection menu.

Performs some additional logic to avoid duplicating decomposition names.

Note that decompositions won't be updated if they have the same name and same metadata headers, if the only things changing are coordinates, or metadata values, the changes should be performed directly on the objects themselves.

Inherited From:
Source:

resize(width, height)

Resizes the container and the individual elements.

Note, the consumer of this class, likely the main controller should call the resize function any time a resizing event happens.

Parameters:
Name Type Description
width float

the container width.
height float

the container height.
Inherited From:
Source:

scaleValue(val, min, range) → {float}

Scaling function to use when sample scaling is based on a metadata category.

Parameters:
Name Type Description
val float

The metadata value for the current sample.
min float

The minimum metadata value in the dataset.
range float

The span of the metadata values.
Overrides:

Type
float

setActive(trulse)

Sets whether or not the tab is visible.

Parameters:

trulse Boolean

option to enable elements.
Inherited From:
Source:

setMetadataField(m)

Changes the selected value in the metadata menu.

Parameters:

Inherited From:

Throws:

Argument m must be a metadata category in one of the decomposition views.

Type
Error
