Scale Color Definition
The "Scale color definition" dialog window lets you create a user-defined color scale.
The "Floating minimum and maximum" checkbox determines the basic type of a scale. If checked, the minimum and maximum values of a scale are automatically adjusted whenever the corresponding variable or a construction stage is changed. In such a case it possible to adjust the following:
- Scale refinement (the minimum number of levels is 4, and the maximum is 100)
- Scale color
- Uniform scale/across zero
The number of scale levels and a scale type are specified in the "Scale generation" dialog window, which opens after pressing the "Generate values" button. It is possible to adjust both values and colors in the table in the left part of the dialog window. The range values can be easily changed in the table. If the box in the "Control color" column is checked, it is possible to choose any color from the combo box. The color on intermediate unchecked rows is automatically blended from the input colors on checked rows. The default values can be recalled anytime after pressing the "Predefined colors" button.
An important option of the program is a definition of ranges with the fixed minimum and maximum. If the "Floating minimum and maximum" checkbox is not checked, the color range is fixed and its minimum and maximum values are input. In contrast to the moving range it is further possible to specify:
- Range end points (in the "Scale generation" dialog window)
- Colors to display values out of the range
When changing a variable or a construction stage the color range remains still the same, keeping the same end ranges. The values outside the range (below the minimum or above the maximum value) are drawn with colors specified in the right part of the window. The minimum and maximum range values are input in the "Scale generation" dialog window. The input minimum and maximum values are linked to the same unit - e.g. when specifying the rage of 0 - 200 kPa, this range is kept the same for all variables specified in kPa - when changing the currently displayed variable to the settlement variable, the current range is switched to that corresponding to the settlement unit.
For both the fixed and floating scale, it is possible to choose the colors in the ranges distributed either uniformly or across zero. The "Uniform" scale means that colors are smoothly spread from the minimum to the maximum value of the scale. The "Across zero" scale draws the colors the space above the selected value with warm colors (yellow, red) and the space below the selected value with cold colors (green, blue).
