Graph IDE ► Graphs ► Date Axis
A date axis is one that has date-unit increments which are not uniform if the unit is year or month, but is uniform if the unit is second, day, or the like. The date axis is constrained to be x-oriented only because we have seen no case of a y-oriented date axis. The following figure shows an x-oriented date axis.
Note the blue rectangular areas showing how February is less in width than January.
The axis has a lot of attributes, which are annotated in the figure above. At present, you can not actually make a axis, it can only be used as a component to a graph.
