20041 "Check for back to front."
Checking this causes the features to plot back-to-front.
There are certain conditions during an automatic constrained scroll (i.e., without the Off control checked) when the system will automatically invert the axis in order to maintain feature positions. What determines what is back-to-front, inside-out or upside-down is the total weight of the loadings on the axis.Besides clicking the axis checkbox or entering a negated value to invert the axis, automatically scrolling past zero will reverse direction.
