Boolean Scalar
Valid for: Chart
If this property is set to 0 (which is the default), a
normal linear scale applies for the alternate Y axis. If set to 1, a logarithmic scale is used
for the alternate Y axis.
Note: You cannot set a logarithmic scale for an axis where any data point (or intercept) is 0
or negative. If this situation occurs, the scale will revert to
linear.
