Color Manager
Colors can be assigned for either nominal (possible values
have to be available) or numeric columns (with lower and upper bounds).
If these bounds are not available, a '?' is provided as a minimum
and maximum value. The values are then computed during execute.
If a column attribute is selected, the color can be changed with the
color chooser.
Dialog Options
- Column(s):
-
Select the column whose possible values or ranges should be used for
color selection.
- Nominal:
-
Assigns colors based on the possible attribute values of the selected
column. The colors are set independently for each attribute value.
- Range:
-
Assigns a color gradient based on a numeric attribute. If
the range is known, the minimum and maximum are displayed in the list,
otherwise a '?' is shown. The color is determined by the position of
the attribute's value within the numeric range: the corresponding color
is set at the same position in the gradient.
- Alpha:
-
Adjust the color's alpha component in the range of 0..255. Please note,
alpha composition is expensive in cases when operations performed are
not hardware-accelerated.
