Most colored surfaces in the QlikView layout can be formatted from the Color Area dialog. Specify either a solid color covering the entire area or a color gradient effect. The color gradient options described below are unavailable for some purposes and will then be grayed out in the dialog, e.g. for text colors.
- Solid Color: The basic option using a single uniform Base Color.
- One Color Gradient: This option introduces the use of varying Brightness to create a color gradient effect.
- Two Colors Gradient: A color gradient effect is created between the Base Color and a specified Second Color.
Color(s) can be fixed or calculated as specified in the Base Color and Second Color groups.
Any color settings can be previewed in the dialog.
In the Base Color group the base color are determined for solid surfaces and gradients.
- Fixed: This alternative specifies a single, basic color. Click the colored button to change the color.
- Calculated: The color may be dynamically calculated from an expression. The expression must be a valid color representation, which is achieved by using the color functions. Click the ... button to open the Edit Expression dialog for easier editing of long formulas. If the result of the expression is not a valid color representation, the program will default to black.
- Brightness: When using a One Color Gradient this slider determines the relative shading/brightness of the color at the opposite end of the gradient. The slider setting goes from darker (left) to brighter (right). At the center position the setting translates as a uniform color.
In the Second Color group the second color is determined for two-color gradients.
- Fixed: This alternative specifies a single, basic color. Click the colored button to change the color.
- Calculated: The color may be dynamically calculated from an expression, using the color functions.
If One Color Gradient or Two Colors Gradient was selected, the direction of the gradient effect is determined by settings in the Gradient Style group. It is possible to achieve different results by combining the available alternatives (Horizontal, Vertical etc.) with clicking one of the four button areas, that represent gradient direction.
