GGU-SLAB: "Normal contours" menu item

After selecting the required parameter, you will see the following dialog box where you can specify preferences for the display of contour lines.

The program shows you the existing smallest and largest values and the spacing of the contour lines. If you want the visualisation to begin at a different value, the initial value can be entered here. You can also vary the spacing, for example, to reduce the number of contour lines drawn.

When you select this menu item the settings displayed here are always those automatically selected by the program. Using the "Old values" button, the preferences used for the previous contour line diagram are adopted. This information is saved with the record.

You can also select from three smoothing out procedures:

• "Do not smooth"
  As a linear method is implemented within the triangle elements, this will provide analysis results without smoothing performed by the program.

• "Method 1" and "Method 2"
  these smoothing out procedures employ two different Bezier splines. Smoothing out intensities can be given for both to acquire smooth contour lines. Method 2 creates very "round" contours, with the danger that the true results may be falsified.

The "Dash preferences" and "Further preferences" buttons can be used to specify the type of visualisation of the contour lines.
