above_line: Optional[ChartPointLine] = None

A vertical line drawn between a line point and the top edge of the chart.

buildabove_line_bgcolorclass-attributeinstance-attribute

above_line_bgcolor: Optional[ColorValue] = None

Fill the area above chart line with the specified color.

buildabove_line_cutoff_yclass-attributeinstance-attribute

above_line_cutoff_y: Optional[Number] = None

Cut off filled area above line chart at specific Y value.

buildabove_line_gradientclass-attributeinstance-attribute

above_line_gradient: Optional[Gradient] = None

Fill the area above chart line with the specified gradient.

buildbelow_lineclass-attributeinstance-attribute

below_line: Optional[ChartPointLine] = None

A vertical line drawn between a line point and the bottom edge of the chart.

buildbelow_line_bgcolorclass-attributeinstance-attribute

below_line_bgcolor: Optional[ColorValue] = None

Fill the area below chart line with the specified color.

buildbelow_line_cutoff_yclass-attributeinstance-attribute

below_line_cutoff_y: Optional[Number] = None

Cut off filled area below line chart at specific Y value.

buildbelow_line_gradientclass-attributeinstance-attribute

below_line_gradient: Optional[Gradient] = None

Fill the area below chart line with the specified gradient.

buildcolorclass-attributeinstance-attribute

color: ColorValue = Colors.CYAN

A color of chart line.

buildcurve_smoothnessclass-attributeinstance-attribute

curve_smoothness: Number = 0.35

Defines the smoothness of a curve line, when curved is set to True.

buildcurvedclass-attributeinstance-attribute

curved: bool = False

Whether to draw this chart line as a curve.

builddash_patternclass-attributeinstance-attribute

dash_pattern: Optional[list[int]] = None

Defines dash effect of the line. The value is a circular list of dash offsets and lengths. For example, the list [5, 10] would result in dashes 5 pixels long followed by blank spaces 10 pixels long. By default, a solid line is drawn.

buildgradientclass-attributeinstance-attribute

gradient: Optional[Gradient] = None

Gradient to draw line's background.

buildpointclass-attributeinstance-attribute

point: Union[None, bool, ChartPointShape] = None

Defines the appearance and shape of a line point (dot).

Setting this property to True will draw a point with default style.

buildpointsclass-attributeinstance-attribute

points: list[LineChartDataPoint] = field(default_factory=list)

A list of points (dots) of LineChartDataPoint type representing a single chart line.

buildprevent_curve_over_shootingclass-attributeinstance-attribute

prevent_curve_over_shooting: bool = False

Whether to prevent overshooting when draw curve line on linear sequence spots.

buildprevent_curve_over_shooting_thresholdclass-attributeinstance-attribute

prevent_curve_over_shooting_threshold: Number = 10.0

Threshold for prevent_curve_over_shooting algorithm.

buildrounded_stroke_capclass-attributeinstance-attribute

rounded_stroke_cap: bool = False

Whether to draw rounded line caps.

buildrounded_stroke_joinclass-attributeinstance-attribute

rounded_stroke_join: bool = False

Whether to draw rounded line joins.

buildselected_below_lineclass-attributeinstance-attribute

selected_below_line: Union[None, bool, ChartPointLine] = None

A vertical line drawn between selected line point and the bottom edge of the chart.

Setting this property to True will draw a line with default style.

buildselected_pointclass-attributeinstance-attribute

selected_point: Union[None, bool, ChartPointShape] = None

Defines the appearance and shape of a selected line point.

buildshadowclass-attributeinstance-attribute

shadow: BoxShadow = field(default_factory=(lambda: BoxShadow(color=(Colors.TRANSPARENT))))

Shadow to drop by a chart line.

buildstep_directionclass-attributeinstance-attribute

step_direction: Optional[Number] = None

Determines the direction of each step.

If not None, this chart will be drawn as a Step Line Chart.

Below are some typical values:

• 0.0: Go to the next spot directly, with the current point's y value.
• 0.5: Go to the half with the current spot y, and with the next spot y for the rest.
• 1.0: Go to the next spot y and direct line to the next spot.

buildstroke_widthclass-attributeinstance-attribute

stroke_width: Number = 2.0

The width of a chart line.
