Color bar is used to view the deviation in the created entities. The color bar looks as shown below.
· Editing Color Bar
A color segment is the area of a color scale enclosed within two cursors, or within a cursor and one of the color scale’s extremities. Within a color segment, numerical values are mapped linearly to colors. There are color scale’s limits to define the different segments of the color bar. These limits can be modified by double-clicking numerical values and entering new values through their related text boxes. New values are made effective by pressing the Enter key.
A color segment can be subdivided by selecting the Split popup menu on the color segment. A new segment is then created on top of the current segment.
A color segment can be deleted by selecting the Delete popup menu on the color segment.
A color segment can be copied by selecting it first, and right-clicking and selecting the Copy menu and then the Paste menu, or by Ctrl+C and Ctrl+V shortcut keys.
· Color Picker
If you select Edit Color from the popup menu on a color segment or double-click it, a Color Picker dialog box then pops up. Note that a tolerance color can not be edited by the color picker. It can be changed in the Tolerance tab of File > Preferences dialog box.
The Color Picker consists in color mode and gray mode; the mode can be changed by left-clicking in each control sector.
In the color mode of the flower shape, the Hue, Saturation and Brightness properties are defined by dragging two little squares using the left mouse button and they are mapped to the currently-selected segment. The Hue property is defined by choosing each petal, the Saturation property is defined by moving a little square to outside from the center of each petal, and the Brightness property is defined by moving a little square to inside from the center of each petal.
In the gray mode, the Brightness property are defined by dragging two little squares using the left mouse button, then the white-black gradient is mapped to the currently-selected segment.
In the Option section, the Colors number defines the number of colors and gradient of the currently-selected segment. You can change it by typing it in the edit box with the ENTER key or dragging a slide bar. The maximum number is up to 100. The Reverse checkbox makes the color gradient of the currently-selected segment inversely. The first and last segments of the color bar can only use one color, so you can control only a little square in the color and gray modes.
The RGB and HSB sections show current properties. The properties can be changed by editing each number.
For the single color gradient, firstly locate a little square to define the Hue and Saturation properties. And then if move the mouse cursor around the line of the selected color, the other little square is automatically snapped to the line. Finally, locate the other little square on the line to define the Brightness property. Then you can move two little squares on the line.
For the fixed brightness gradient, firstly locate a little square to define the Hue and Saturation properties and locate the other little square to define the Brightness property. And then if you drag the other little square while pressing down the Shift key, then the color can be changed while the brightness is fixed.
