LogarithmicAxis class

Logarithmic axis uses logarithmic scale and displays numbers as axis labels.

provides options to customize the range of log axis, use the minimum, maximum, and interval properties. By default, the range will be calculated automatically based on the provided data.

Note: This is only applicable for SfCartesianChart.

Creating an argument constructor of LogarithmicAxis class.

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
autoScrollingMode → AutoScrollingMode
Determines whether the axis should be scrolled from the start position or end position.
finalinherited
axisLine → AxisLine
Customizes the appearance of the axis line. The axis line is visible by default.
finalinherited
crossesAt → dynamic
Customize to place the axis crossing on another axis based on the value
finalinherited
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 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.
finalinherited
interval → double?
Axis interval value.
finalinherited
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 numeric axis labels.
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
logBase → double
The base value for logarithmic axis. The axislabel will render this base value.i.e 10,100,1000 and so on.
final
majorGridLines → MajorGridLines
Customizes the appearance of the major grid lines.
finalinherited
majorTickLines → MajorTickLines
Customizes the appearance of the major tick lines.
finalinherited
maximum → double?
The maximum value of the axis. The axis will end at this value.
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 → double?
The minimum value of the axis.
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
name → String?
Name of an axis.
finalinherited
numberFormat → NumberFormat?
Formats the logarithmic axis labels with globalized label formats.
final
opposedPosition → bool
Opposes the axis position.
finalinherited
placeLabelsNearAxisLine → bool
Consider to place the axis label respect to near axis line.
finalinherited
plotBands → List<PlotBand>
Render the plot band in axis
finalinherited
plotOffset → double
Padding for plot area. The axis is rendered in chart with padding.
finalinherited
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
finalinherited
rangePadding → ChartRangePadding
Padding for minimum and maximum values in an axis.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
tickPosition → TickPosition
Position of the tick lines.
finalinherited
title → AxisTitle
Customizes the appearance of the axis title.

visibleMaximum → double?
The minimum visible value of the axis.
final
visibleMinimum → double?
The minimum visible value of the axis.
final
zoomFactor → double
Zoom factor of an axis.
finalinherited
zoomPosition → double
Position of the zoomed axis. The value ranges from 0 to 1.
