On the View Attributes dialog, you can define the scale and colors for the presentation of stresses in individual bar sections.
Available tabs on the dialog:
On each of the first 4 tabs, you can select a palette of colors (full palette, standard colors, and shades of green and blue). After you select the palette, clear the symbol next to any of the colors that you do not want on the stress map.
On the View Attribute tab, you select elements to be presented on the screen.
If the option is selected (the symbol displays), the element will be presented on the screen. Use Quick Redraw to update the stress map after the display parameters are changed.
