                        -getDeltaFromRangeMin:max:minorsPerMajor:maxTicks:

Given an absolute Axis Min and Max, returns a ISCIAxisDelta instance containing sensible MinorDelta and MajorDelta values.

Declaration

Objective-C

- (nonnull id<ISCIAxisDelta>)
    getDeltaFromRangeMin:(nonnull id<ISCIComparable>)min
                     max:(nonnull id<ISCIComparable>)max
          minorsPerMajor:(unsigned int)minorsPerMajor
                maxTicks:(unsigned int)maxTicks;

Swift

func getDeltaFromRange(min: any ISCIComparable, max: any ISCIComparable, minorsPerMajor: UInt32, maxTicks: UInt32) -> any ISCIAxisDelta

Parameters

`min`	The axis VisibleRange min value.
`max`	The axis VisibleRange max value.
`minorsPerMajor`	The number of Minor Delta ticks per Major Tick.
`maxTicks`	The max ticks.

Return Value

The ISCIAxisDelta instance.
