ChartAxis class abstract

This class holds the properties of ChartAxis.

Charts typically have two axes that are used to measure and categorize data: a vertical (Y) axis, and a horizontal (X) axis. Vertical(Y) axis always uses a numerical scale. Horizontal(X) axis supports Category, Numeric, Date-time, Logarithmic.

Provides the options for plotOffset, series visible, axis title, label padding, and alignment to customize the appearance.

Properties

anchorRangeToVisiblePoints → bool
Determines the value axis range, based on the visible data points or based on the overall data points available in chart.
final
associatedAxisName → String?
Axis line crossed on mentioned axis name, and applicable for plot band also.
final
autoScrollingDelta → int?
The number of data points to be visible always in the chart.
final
autoScrollingMode → AutoScrollingMode
Determines whether the axis should be scrolled from the start position or end position.
final
axisLine → AxisLine
Customizes the appearance of the axis line. The axis line is visible by default.
final
crossesAt → dynamic
Customize to place the axis crossing on another axis based on the value
final
desiredIntervals → int?
The number of intervals in an axis.
final
edgeLabelPlacement → EdgeLabelPlacement
Position of the edge labels.
final
enableAutoIntervalOnZooming → bool
Enables or disables the automatic interval while zooming.
final
hashCode → int
The hash code for this object.
no setterinherited
interactiveTooltip → InteractiveTooltip
Customizes the crosshair and selection zooming tooltip. Tooltip displays the current axis value based on the crosshair position/selectionZoomRect position at an axis.
final
interval → double?
Axis interval value.
final
isInversed → bool
Inverts the axis.
final
isVisible → bool
Toggles the visibility of the axis.
final
labelAlignment → LabelAlignment
Alignment of the labels.
final
labelIntersectAction → AxisLabelIntersectAction
Axis labels intersecting action.
final
labelPosition → ChartDataLabelPosition
Position of the labels.
final
labelRotation → int
Angle for axis labels. The axis labels can be rotated to any angle.
final
labelsExtent → double?
Specifies the fixed width for the axis labels. This width represents the space between axis line and axis title.
final
labelStyle → TextStyle
Customizes the appearance of the axis labels.
final
majorGridLines → MajorGridLines
Customizes the appearance of the major grid lines.
final
majorTickLines → MajorTickLines
Customizes the appearance of the major tick lines.
final
maximumLabels → int
The maximum number of labels to be displayed in an axis in 100 logical pixels.
final
maximumLabelWidth → double?
Specifies maximum text width for axis labels.
final
minorGridLines → MinorGridLines
Customizes the appearance of the minor grid lines.
final
minorTickLines → MinorTickLines
Customizes the appearance of the minor tick lines.
final
minorTicksPerInterval → int
Interval of the minor ticks.
final
name → String?
Name of an axis.
final
opposedPosition → bool
Opposes the axis position.
final
placeLabelsNearAxisLine → bool
Consider to place the axis label respect to near axis line.
final
plotBands → List<PlotBand>
Render the plot band in axis
final
plotOffset → double
Padding for plot area. The axis is rendered in chart with padding.
final
rangeController → RangeController?
Controller used to set the maximum and minimum values for the chart.By providing the range controller, the maximum and The minimum range of charts can be customized
final
rangePadding → ChartRangePadding
Padding for minimum and maximum values in an axis.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
tickPosition → TickPosition
Position of the tick lines.
final
title → AxisTitle
Customizes the appearance of the axis title.
final
zoomFactor → double
Zoom factor of an axis.
final
zoomPosition → double
Position of the zoomed axis. The value ranges from 0 to 1.
final
