Use the Scales Tab of the Gauge Designer dialog (figure 1 below) to set scale-related properties of the main gauge.

Scales are either circular or linear in nature, and a scale's values can be pointed to by an associated pointer. See the Scales topic for more information.

Scales

This listbox displays all scales of the control.

Use the  and  buttons to respectively add and delete scales.

Minimum

Determines the starting value of the scale. This can be any valid report expression, as long as it equates to a numerical value. In addition a Gauge statistical formula can be applied by clicking on the  icon if an expression is used.

Maximum

Determines the end value of the scale. This can be any valid report expression, as long as it equates to a numerical value. In addition a Gauge statistical formula can be applied by clicking on the  icon if an expression is used.

Labels Interval

If the Automatic checkbox is checked then the interval of the scale labels will be calculated automatically.

De-selecting this checkbox will result in the display of a numeric spin control that lets you explicitly set the interval of labels.

Width

Determines the width of the scale.

For circular scales the width is measured as a percentage of the scale's radius. For linear scales it is measured as a percentage of the associated linear gauge's width.

Circular Scale Properties

Start Angle

Determines the angle at which the start point of the scale is plotted. The specified angle must be positive, and is applied clockwise, starting from the 180 degree position.

Sweep Angle

Determines the angle from the start point of the scale to the end point of the scale. The specified angle must be positive, and is applied clockwise, starting from the 180 degree position of the scale.

Radius

Determines the radius of scale. Measured as a percentage of the circular gauge's width, starting from the center of the gauge to the edge of the scale.

Linear Scale Properties

Start Margin

Use the spin control to set the start margin. The start margin is measured as a percentage of the linear gauge's length, and starts from the bottom of the gauge to the beginning of the scale.

End Margin

Use the spin control to set the end margin. The end margin is measured as a percentage of the linear gauge's length, and starts from the top of the gauge to the end of the scale of the scale.

Position

Determines the position of the scale, relative to the linear gauge.

The position is measured as a percentage of the control's width.
