- All Implemented Interfaces:
RrdGraphConstants
- Direct Known Subclasses:
TimeAxis, ValueAxis, ValueAxisLogarithmic, ValueAxisMrtg
Abstract base class for graph axes in RRD graphs. Provides common functionality for time and value axes. All axis implementations must implement the
draw() method to render the axis.Nested Class Summary
