`linefill` (library)

Definition Functions for filling the region between two line drawings. One fill per ordered line pair; creating another fill on the same pair replaces the previous one. Deleting a line also deletes fills that use it. Example

//@lipi=2
indicator("linefill Library Example", overlay=true)
if barstate.islast {
    upper = line.new(bar_index[20], talib.highest(high, 20), bar_index, talib.highest(high, 20), color=color.green)
    lower = line.new(bar_index[20], talib.lowest(low, 20), bar_index, talib.lowest(low, 20), color=color.red)
    linefill.new(upper, lower, color.new(color.gray, 0.2))
}

`linefill.all` (function)

Definition Returns the array of all existing linefill objects (same as the linefill.all variable). Syntax

linefill.all() → series array<linefill>

Returns series array<linefill> An array of linefill IDs, oldest to newest. Example

//@lipi=2
indicator("linefill.all Function Example", overlay=true)
plot(array.length(linefill.all), title="Fills")

`linefill.delete` (function)

Definition Deletes a linefill. Does not delete the two lines it was attached to. Deleting either line also deletes attached fills. Syntax

linefill.delete(series linefill id) → void

Parameters

Name	Type	Required	Description
`id`	`series linefill`	yes	Linefill object to delete.

Returns void void Example

//@lipi=2
indicator("linefill.delete Example", overlay=true)
if barstate.islast {
    l1 = line.new(bar_index[10], high[10], bar_index, high)
    l2 = line.new(bar_index[10], low[10], bar_index, low)
    f = linefill.new(l1, l2, color.new(color.blue, 0.7))
    linefill.delete(f)
}

`linefill.get_line1` (function)

Definition Returns the first line used when the fill was created. Syntax

linefill.get_line1(series linefill id) → series line

Parameters

Name	Type	Required	Description
`id`	`series linefill`	yes	Linefill object.

Returns series line The first line object, or na if the fill or line no longer exists. Example

//@lipi=2
indicator("linefill.get_line1 Example", overlay=true)
if barstate.islast {
    l1 = line.new(bar_index[10], high[10], bar_index, high)
    l2 = line.new(bar_index[10], low[10], bar_index, low)
    f = linefill.new(l1, l2, color.new(color.blue, 0.7))
    line.set_color(linefill.get_line1(f), color.green)
}

`linefill.get_line2` (function)

Definition Returns the second line used when the fill was created. Syntax

linefill.get_line2(series linefill id) → series line

Parameters

Name	Type	Required	Description
`id`	`series linefill`	yes	Linefill object.

Returns series line The second line object, or na if the fill or line no longer exists. Example

//@lipi=2
indicator("linefill.get_line2 Example", overlay=true)
if barstate.islast {
    l1 = line.new(bar_index[10], high[10], bar_index, high)
    l2 = line.new(bar_index[10], low[10], bar_index, low)
    f = linefill.new(l1, l2, color.new(color.blue, 0.7))
    line.set_color(linefill.get_line2(f), color.red)
}

`linefill.new` (function)

Definition Creates a fill between two lines. If a fill already exists for this ordered pair (line1, line2), the previous fill is deleted and replaced. (line2, line1) is a different pair. Syntax

linefill.new(series line line1, series line line2, series color color) → series linefill

Parameters

Name	Type	Required	Description	Default
`line1`	`series line`	yes	First line object. The fill tracks this line’s current points.
`line2`	`series line`	yes	Second line object. The fill tracks this line’s current points.
`color`	`series color`	no	Fill color. Optional. Default is na.	`na`

Returns series linefill The ID of the created linefill, or na if either line is invalid. Example

//@lipi=2
indicator("linefill.new Example", overlay=true)
if barstate.islast {
    l1 = line.new(bar_index[20], high[20], bar_index, high, color=color.green)
    l2 = line.new(bar_index[20], low[20], bar_index, low, color=color.red)
    f = linefill.new(l1, l2, color.new(color.blue, 0.7))
}

`linefill.set_color` (function)

Definition Sets the fill color of an existing linefill. Syntax

linefill.set_color(series linefill id, series color color) → void

Parameters

Name	Type	Required	Description
`id`	`series linefill`	yes	Linefill object.
`color`	`series color`	yes	New fill color.

Returns void void Example

//@lipi=2
indicator("linefill.set_color Example", overlay=true)
if barstate.islast {
    l1 = line.new(bar_index[10], high[10], bar_index, high)
    l2 = line.new(bar_index[10], low[10], bar_index, low)
    f = linefill.new(l1, l2, color.new(color.blue, 0.7))
    linefill.set_color(f, color.new(color.orange, 0.7))
}
