Setting Up Scales

To set up indicator scales, use the Scale tab on the side panel.

Make sure that the side panel is displayed.
Select the indicator in the working area.
Select the Format radio button on the side panel and go to the Scale tab.

A scale is set up in several steps:

Set up basic scale parameters.

Set up scale intervals.

Setting Up Basic Scale Parameters

These parameters are used to set up basic scale parameters:

In the Current Scale drop-down list select the scale to be set up and determine basic parameters for this scale:

Width. Height. Specify the scale width and height relative to the indicator width and height. The value must be in the range [1; 100]. Width and height of each scale is specified separately.

Length. Specify scale length in degrees. Set values in the From and To boxes in the range between [-360; 360]. The sum of absolute values of the From and To boxes must not exceed 360 degrees. The scale rendering is executed clockwise.

NOTE. On entering the negative value to the From box, it recalculates it to the positive one using the formula: 360°- α, where α - is an entered value to the From box.

For example:

The value equal to 180 is entered to the From box and the value equal to 0 is entered to the To box.
The value equal to 90 is entered to the From box and the value equal to -90 is entered to the To box.
The value equal to 215 is entered to the From box and the value equal to -35 is entered to the To box.
The value equal to 35 is entered to the From box and the value equal to -215 is entered to the To box.
The value equal to 135 is entered to the From box and the value equal to 45 is entered to the To box.

See below from left to right results of examples of setting scale heights:

Range. Determine scale value range. The setting works together with interval setting.

Min and Max. Enter the minimum and maximum values in the Min and Max fields. By default.

Values in the range [0; 180] are set for Scale1.
Values in the range [0; 180] are set for Scale2.
Numeric values of the indicator from minimum to maximum are set for Scale3.

From and To. To limit slace value range, enter the start and end value in the From and To fields. By default values in the range from minimum to maximum are set.

Consider how to set up values of the Range parameter for the Scale3 scale. By default the indicator values are in the range from [150; 230] which corresponds to the dimension value range from minimum to maximum:

For example:

The [100; 250] range is set in the Min and Max fields.
The range [110; 240] is set in the From and To fields.

As a result the indicator looks as follows:

Fill. Parameters of scale background fill. The checkbox is deselected by default, and the background fill is not used. To set up the fill, select the checkbox and select the radio button that corresponds to the required fill method:

Single Color. Background is filled with one color. Select background color in the corresponding color palette.
Overflow. Background is filled with gradient. Use the Tilt box to set angle of gradient tilt.
Floating color palettes are used to work with gradient colors. To change color share in the gradient, move the corresponding color palette.
Use the Another Color button to add a new color, and the Delete button to delete the current color.

Border. Parameters of scale border. The checkbox is deselected by default, and no border is displayed. To display a border, select the checkbox and use appropriate boxes to set the following parameters: type, thickness and color of border line.

Transparency. Parameters of scale transparency. The checkbox is selected by default, and scale transparency can be adjusted: 100% corresponds to transparency (the scale becomes invisible), 0% corresponds to opacity.

Setting Up Scale Intervals

The parameters that are used to set up scale intervals:

Set the Intervals checkbox and select the main tick mark form. Also, specify the following parameters:

Count. Specify the number of major tick marks.

Color. Specify the color of major tick marks.

Size. Set size of major tick marks in pixels or in percentage.

Minor. Parameters of minor scale tick marks. To display minor tick marks, select the checkbox and select the count, color and size of tick marks.

Labels. Parameters of labels for the scale tick marks. To display labels, select the checkbox and set label parameters in appropriate boxes: font name, size and color, style and alignment.
