Logarithmic axis in JavaScript 3D Chart control

18 Nov 20181 minute to read

Logarithmic axis uses logarithmic scale and it is very useful in visualizing data, when it has numerical values in both lower order of magnitude (eg: 10^-6) and higher order of magnitude (eg: 10⁶).

Note: To use logarithmic axis, we need to inject Logarithmic3D module using the Chart3D.Inject(Logarithmic3D) method and set the valueType of the axis to Logarithmic.

Range

The range of an axis will be calculated automatically based on the provided data and it can also be customized by using the minimum, maximum and interval properties of the axis.

Logarithmic base

Logarithmic base can be customized by using the logBase property of the axis. For example when the logBase is 5, the axis values follows 5^-2, 5^-1, 5⁰, 5¹, 5² etc.

Logarithmic interval

The interval of the logarithmic axis can be customized by using the interval property in the axis. When the logarithmic base is 10 and logarithmic interval is 2, then the axis labels are placed at an interval of 10². The default value of the interval is 1.
