Note: To use datetime axis, we need to inject DateTime using <Inject services={[DateTime]}> method and set the valueType of axis to DateTime.

Logarithmic Axis

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) and set the valueType of axis to Lograthmic.
