DateTimeAxis class

This class holds the properties of the DateTime axis.

The date-time axis uses a date-time scale and displays date-time values as axis labels in the specified format.

The range of the Date time can be customized by minimum and maximum properties, also change data label format by the dateFormat.

Provides the options for range padding, interval, date format for customizing 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.
finalinherited
associatedAxisName → String?
Axis line crossed on mentioned axis name, and applicable for plot band also.
finalinherited
autoScrollingDelta → int?
The number of data points to be visible always in the chart.
finalinherited
autoScrollingDeltaType → DateTimeIntervalType
Defines the type of delta value in the DateTime axis.
final
autoScrollingMode → AutoScrollingMode
Determines whether the axis should be scrolled from the start position or end position.
finalinherited
axisBorderType → AxisBorderType
Border type of the axis label.
finalinherited
axisLabelFormatter → ChartLabelFormatterCallback?
Called while rendering each axis label in the chart.
finalinherited
axisLine → AxisLine
Customizes the appearance of the axis line. The axis line is visible by default.
finalinherited
borderColor → Color?
Border color of the axis label.
finalinherited
borderWidth → double
Border width of the axis label.
finalinherited
crossesAt → dynamic
Customization to place the axis crossing on another axis based on the value.
finalinherited
dateFormat → DateFormat?
Formats the date-time axis labels. The default data-time axis label can be formatted with various built-in date formats.
final
desiredIntervals → int?
The number of intervals in an axis.
finalinherited
edgeLabelPlacement → EdgeLabelPlacement
Position of the edge labels.
finalinherited
enableAutoIntervalOnZooming → bool
Enables or disables the automatic interval while zooming.
finalinherited
hashCode → int
The hash code for this object.
no setteroverride
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.
finalinherited
interval → double?
Axis interval value.
finalinherited
intervalType → DateTimeIntervalType
Customizes the date-time axis intervals. Intervals can be set to days, hours, milliseconds, minutes, months, seconds, years, and auto. If it is set to auto, interval type will be decided based on the data.
final
isInversed → bool
Inverts the axis.
finalinherited
isVisible → bool
Toggles the visibility of the axis.
finalinherited
labelAlignment → LabelAlignment
Alignment of the labels.
finalinherited
labelFormat → String?
Formats the date time-axis labels. The labels can be customized by adding desired text to prefix or suffix.
final
labelIntersectAction → AxisLabelIntersectAction
Axis labels intersecting action.
finalinherited
labelPosition → ChartDataLabelPosition
Position of the labels.
finalinherited
labelRotation → int
Angle for axis labels. The axis labels can be rotated to any angle.
finalinherited
labelsExtent → double?
Specifies the fixed width for the axis labels. This width represents the space between axis line and axis title.
finalinherited
labelStyle → TextStyle?
Customizes the appearance of the axis labels.
finalinherited
majorGridLines → MajorGridLines
Customizes the appearance of the major grid lines.
finalinherited
majorTickLines → MajorTickLines
Customizes the appearance of the major tick lines.
finalinherited
maximum → DateTime?
Maximum value of the axis. The axis will end at this date.
final
maximumLabels → int
The maximum number of labels to be displayed in an axis in 100 logical pixels.
finalinherited
maximumLabelWidth → double?
Specifies maximum text width for axis labels.
finalinherited
minimum → DateTime?
Minimum value of the axis. The axis will start from this date.
final
minorGridLines → MinorGridLines
Customizes the appearance of the minor grid lines.
finalinherited
minorTickLines → MinorTickLines
Customizes the appearance of the minor tick lines.
finalinherited
minorTicksPerInterval → int
Interval of the minor ticks.
finalinherited
multiLevelLabelFormatter → MultiLevelLabelFormatterCallback?
Called while rendering each multi-level label.
finalinherited
multiLevelLabels → List<ChartMultiLevelLabel>?
Provides the option to group the axis labels. You can customize the start, end value of a multi-level label, text, and level of the multi-level labels.
finalinherited
multiLevelLabelStyle → MultiLevelLabelStyle
Customize the multi-level label’s border color, width, type, and text style such as color, font size, etc.
