AutoScaleLog calculates parameters for logarithmic scaled diagram axes.
Return Value
rvScale = [rsMin, rsMax, rsDelta, rsFormat] rvScale is a real vector with 4 elements: rvScale = [rsMin, rsMax, rsDelta, rsFormat]. rsMin is a recommended minimum value for the diagram axis and rsMax a recommended maximum value. rsDelta is the recommended distance between 2 labels and rsFormat is the recommended number of decimal places for the labels. If rsFormat is negative, an exponential format is recommended.
Parameters
rsMin is the approximate minimum value of the axis.
rsMin is the approximate maximum value of the axis.
Example
* AutoScaleLog(-230.9, 1112.13)
1.0000 10000.0000 10.0000 0.0000
* AutoScaleLog(-230.19212, 11112212.1321)
1.0000 1e+008 10.0000 -1.0000
