Color Map
Choose from various predefined color maps using the color map combo-box. A color map, along with the values specified, defines how values are mapped to a color on the contour image.
If a color map showing both high and low values is desired (such as for bus voltages), use of "Blue = Low, Red = High" is recommended. If a color map showing only high values is desired (such as for line flows), use of "Weather Radar, Nominal to High" is recommended.
A user may also define additional color maps by going to the Custom Color Map Tab.
Check this box to reverse the colors of the selected color map, so the low color becomes the high color, and vice versa.
Brightness
Modify the brightness track bar to change the brightness of the color map.
Use cell values directly
Use the specified field below
Select this option to use a different field value to do the contouring.
Value
Select the quantity to use in the contouring from the Value dropdown box or click the Find Value button to find the desired field.
Checking this box will cause the contour to draw a color key showing which colors are mapped to which values. You can also give the color key a title, unit label, and specify the number of digits to display in numerical values.
Title
Title for the color key.
Entry Labels
Units of the contoured value displayed on the color key.
Dec. Pts.
Number of decimal places of the contoured value displayed on the color key.
Scalar
Multiplication factor that can be applied to the values when drawing the color key.
Use Equal Spacing For Discrete Maps
This option will draw the color key with equal spacing for all colors in the map, regardless of how close or distant the values the colors represent.
Use absolute value
Check this check-box to use the absolute values of the quantity selected at the Value dropdown box (above).
Values
These values along with the color map define how to convert your values into a color for the contour. The values are:
Maximum The largest value allowed in the contour. All values above this will be mapped to the highest color. This value corresponds to 100% in the color map.
Break High This value is used by some color maps to highlight a lower limit. This value corresponds to 75% in the color map.
Nominal This value is the nominal value for the contour. Values around this will be mapped to the middle color. This value corresponds to 50% in the color map.
Break Low This value is used by some color maps to highlight a lower limit. This value corresponds to 25% in the color map.
Minimum The smallest value allowed in the contour. All values below this will be mapped to the lowest color. This value corresponds to 0% in the color map.
Note: a representation of the color map is shown to the right of the values.
