Define a Scale for a Gauge Widget

Use the Properties page (accessed within the Gauge Widget Properties window) to define the scale for a Gauge Widget. Properties include:

• Minimum and maximum scale values.
• Auto-raise value: Enables the gauge to automatically raise the maximum scale value if the value exceeds this limit.
• Logarithmic scale (Linear, Speedometer, and Thermometer gauges only): Use a logarithmic scale to use intervals corresponding to orders of magnitude rather than a standard linear scale. This is helpful when the data covers an exceedingly large range of values.
• Display properties for the gauge and scale (example: Text alignment, Horizontal orientation, and scale direction).

To define a scale for a Gauge Widget:

1. Create a Widget
2. In the Type drop-down, select Gauge.
3. Click the Properties page.
4. Define the scale for the gauge:
   1. Minimum/Maximum values: Define the minimum and maximum values for the gauge's scale (example: 1-99). Some scales are physical (example: Thermometer and Speedometer displays); on Text and Numeric gauges, min/max values represent the limit of legal values (example: Min and max number of records to display on a Text gauge).

      Note: Numeric gauges display an error if the value is out of range. Other gauges "top out."

   2. Auto-Raise Value: Select this check box to enable the gauge to automatically raise the maximum if its values exceed this limit.
   3. Logarithmic scale: Select this check box to define the scale using intervals corresponding to orders of magnitude rather than a standard linear scale. This is helpful when the data covers an exceedingly large range of values.
5. Define display properties for the gauge and scale (these vary by the type of gauge):
   1. Text Alignment (Text gauge only): Select the alignment for the scale, with respect to the Widget's bounding box (example: Bottom Center).
   2. Flip the horizontal orientation (Angle Speedometers only): Select this check box to flip the angle of the speedometer so that it opens to the left (flipped) instead of the right (default).
   3. Reverse the scale direction (Angle Speedometers only): Select this check box to flip the scale so that it displays values from maximum-to-minimum (reversed; example: 5-1) rather than minimum-to-maximum (default; example: 1-5).

6. Click OK.
