RockPlot2D | View | Stretch, Best Fit, Vertical Exaggeration
When you have a diagram displayed in a RockPlot2D window, you may change the size of the window as well as change how the diagram is plotted within its window.
Step-by-Step Summary
Follow these steps to adjust the display of an image in the plot window:
- Click in the RockPlot2D window containing the image to be rescaled.
- Resize the window as you wish.
- Select one of the scaling options.
- Best Fit
- The Best Fit toolbar button
and View menu command will fill the plot window as best it can with the current diagram while keeping the currently-established vertical exaggeration the same. If, for example, the vertical exaggeration is set to "1", then the Best Fit scaling will resize the image within the window while keeping the relative axis scaling the same. If the vertical exaggeration is currently set to "10", then the Best Fit scaling will resize and maintain this exaggeration. This tool is typically used to expand or contract the image but not change its shape within a resized plot window.
- Examples:
- RockWorks just plotted a contour map on the screen, you enlarge the plot window for a better view, and then click Best Fit to enlarge the map.
- You've created a cross section that looks best when viewed at a Vertical Exaggeration of "10". You adjust that setting (as described below) and then resize the plot window to get a better view. You then click Best Fit to enlarge the cross section in the new window.
- Stretch
- The Stretch toolbar button
or View menu command is used to fill the current window with the diagram, stretching or condensing the image both horizontally and vertically as necessary. The vertical exaggeration represented after stretching will be displayed in the VE item in the toolbar.
- ! Note that if you prefer to have the vertical axis stretched or compressed by a specific scale factor, use the Vertical Exaggeration option.
- Example: Let's say you have opened a RockWorks strip log diagram. You can use your mouse to resize the RockPlot2D window to be long vertically and narrow horizontally. Then, choose the Stretch button to fill this window with the log.
- Vertical Exaggeration
- The value displayed on the "VE" button in the upper toolbar represents the amount by which the vertical axis is scaled differently than the horizontal axis. At a Vertical Exaggeration of "1", the horizontal and vertical axes are scaled with the same number of map or diagram units per inch. At a Vertical Exaggeration of "2", the vertical axis is twice as long, relatively, and the image is stretched longer up-and-down. At "0.5" the vertical axis is half as long relatively, and the image is flattened.
- To enter a different Vertical Exaggeration factor, click on the VE button
or View | Vertical Exaggeration menu command and type into the prompt an exaggeration value. This can be any real number value. When you click OK the program will redraw the image in the screen window, with the indicated exaggeration factor.
