Suppose one has a map with multiple contour layers, each layer with a specific data range in the grid, but vastly different among themselves. Say, one grid with data range from 0 to 10, other from 100 to 150 and a third one with data range from 1000 to 50000. This is an usual situation in environmental analysis. If one wants to add a profile to one of the Contour layers, say the one with data range from 100 to 150, the logical idea would be to put the desired Contour layer on top of the others, or to deactivate the undesired ones. But in Surfer 14, all Contour layers are profiled simultaneously. The output is a profile plot with a meaningless curve because the vertical axis would have a global range from 0 to 50000. That is bad programming logic! The profiling tool should collect data only of the active contour layers. Please fix that.
