Specification of Logarithmic Base number (e.g. 10, 2, natural log).
Defaults to 10 if omitted.
Examples:
10
| powers of ten (1, 10, 100, 1000, 10000, ...).e
| natural logarithm (1e, 2e, 3e, 4e, ...)type
must be set to 'logarithmic'
for this to effect!
Specify Axis position in chart.
Default is bottom for X Axes, and left for Y Axes.
Setting to true
will result in the opposite side (top for X Axes, right for Y Axes).
Type of Axis.
Each type section contains information about related Axis zooming limits,
as in constraints on the magnitude of Axis interval, which is calculated as Math.abs(end - start)
.
When the limit is reached, the Axis will not be able to zoom in and out further by programmatic calls (Axis.setInterval) or user interactions.
linear
:
Default Axis type. Same behavior as type: undefined
.
Achievable zoom range depends on the magnitude of Axis interval start; Following table contains reference values on the achievable zoom ranges - in practice zoom range might be limited sooner or later.

logarithmic
:
Logarithmic Axis. By default base number will be 10
.
With Logarithmic Axis, range must always start above 0! (log is not defined at 0).
NOTE: Not all series types support logarithmic axes! Attaching a non-supported Series will crash the application.

As of yet logarithmic
and linear-highPrecision
can't be combined as X + Y Axes.
linear-highPrecision
:
Behaves otherwise similarly as linear
, but zoom range is significantly improved, with the drawback of a considerable performance drop.
Achievable zoom range depends on the magnitude of Axis interval start; Following table contains reference values on the achievable zoom ranges - in practice zoom range might be limited sooner or later.

and linear-highPrecision
can't be combined as X + Y Axes.
High precision Axis is an experimental feature, which means that it can be significantly altered in minor version releases.
Interface for specifying Axis (XY) configurations that can't be changed after creation of the Axis.
Example usage:
ChartXY({ defaultAxisY: { opposite: true, } })
ChartXY({ defaultAxisX: { type: 'logarithmic', base: 10, } })
ChartXY.addAxisX({ type: 'logarithmic', base: 'natural', })
NOTE: Some series / features do not support all available non-default Axis types (logarithmic, high precision, ..).
Additionally, there can be further limitations in combinations of two Axis types. For example, as of now
logarithmic
andlinear-highPrecision
can't be combined as X + Y Axes.Refer to documentation of AxisOptions.type for detailed information.
