Vertical Exaggeration Factor

Vertical Exaggeration Factor: Use this setting to define how much vertical stretch should be applied to this diagram. A setting of "1" means the horizontal (distance) and vertical (elevation) axes will be plotted at the same scale. A setting of "5" means that the vertical axis will be stretched by a factor of 5. By setting this factor before generating the diagram can help assure appropriately-placed perimeter annotations.

! Note that you can always change the vertical exaggeration at which the image is displayed, in the RockPlot2D window itself. But, by telling the program up-front how stretched the profile will be, you'll get better placement of the diagram annotations.

Here's a possible scenario: Let's say that we have a project area that we have a series of shallow boreholes (<100 meters deep) within a very large project area 60,000 x 60,000 meters. These boreholes are separated by large distances (average spacing = 6000 meters). Creating a meaningful cross-section is difficult. With a vertical exaggeration of 1.0, a typical profile looks like this:

If we attempt to vertically exaggerate (by 10x) this diagram within RockPlot2D, the profile title will be too high, the coordinate axes will be too low, and the tick-marks within the coordinate axes will be stretched, as shown by the following example.

This dilemma is solved by the "Vertical Exaggeration Factor", which automatically adjusts the positions and dimensions of the offending entities (i.e. the title, the endpoint labels, and the coordinate axes) based on the user defined exaggeration factor. In the following example, we have selected an "Intended Vertical Exaggeration Factor" of 10.0 and plotted the diagram within RockPlot2D at a vertical exaggeration of 10.0.
