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:
- Create a Widget
- In the Type drop-down, select Gauge.
- Click the Properties page.
- Define the scale for the gauge:
- 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."
- Auto-Raise Value: Select this check box to enable the gauge to automatically raise the maximum if its values exceed this limit.
- 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.
- 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).
- Define display properties for the gauge and scale (these vary by the
type of gauge):
- Text Alignment (Text gauge only): Select the alignment for the scale, with respect to the Widget's bounding box (example: Bottom Center).
- 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).
- 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).
