Labeling Calculation Points

Calculation Points may be labeled in a number of ways; labeling the first point in a description of points, labeling every point, labeling each line of points and/or labeling observer positions. Specifying labeling for lines of points and observer positions, where these calculations are not defined, will have no effect.

Calculation labels may be applied to calculation grids in three ways: when first specifying the calculation entity, by editing the calculation entity after creation, or from Project Manager in the CalcPts Entities matrix.

Calculation labels are dynamic and will update themselves, upon redraw, if the calculation has been modified.

Label the first point in this description

This labeling option is available for all calculation options; grids, scattered points, lines, surfaces, etc.

- Click in the selection box adjacent to the labeling options you are interested in.
- If desired, change the current font and text size.
- Click Ok.

###### The first point may be labeled with the following options:

Calculation Points Label - This option will extract the label name associated with this calculation and locate it below the first calculation point.

Description - This option will extract the user-defined description associated with this calculation and locate it below the first point.

Project Name - This option will extract the project name associated with this calculation and locate it below the first point.

Summary - This option will list the calculation metric selected in the corresponding dialog (e.g., Average, Maximum, Minimum, Avg/Min, Max/Avg and Max/Min ratios). When this option is selected, the Label also includes the metric type and unit of measurements (e.g. Illuminance (Fc), L_Diffuse (Cd/sq. meter), etc.)

Meter Orient and Tilt - This option will extract the meter and tilt information of the first point. This is useful if every point in the calculation exhibits the same meter rotation (horizontal meter, normal to grid and fixed orient and tilt angles). If each point exhibits a different orientation and tilt, as in variable meter aiming, then this labeling option will not describe the calculation's meter as a whole. In this case, you may want to label the meter of each point.

X-Y Coordinates - This option extracts the X and Y coordinate information of the first point.

Z coordinate - This option extracts the Z coordinate information of the first point. This comes in handy when creating calculation points with one elevation, in that one label describes the Z coordinate of each point.

Label each point in this description

This labeling option is available for all calculation options; grids, scattered points, lines, surfaces, etc.

- Select the Each Point tab, so that it moves to the forefront of the dialog.
- Click in the selection box adjacent to the labeling option(s) you are interested in.
- If desired, change the current font and text size.
- Click Ok.

Each point may be labeled with the following options. However, generally labeling each point is not recommended due to the additional overhead required and longer refresh times. Consider the circumstances (such as widely scattered points) before selecting these options:

Calculation Points Label - This option will extract the description name, associated with this calculation.

Description - This option will extract the user-defined description associated with this calculation and locate it below the first point.

Point Number - This option will extract the point number associated with each point.

Meter Orient and Tilt - This option will extract the meter and tilt information of each point. If every point in the calculation exhibits the same meter rotation (horizontal meter, normal to grid and fixed orient and tilt angles), you may want to label the first point, instead.

X-Y Coordinates - This option extracts the X and Y coordinate information of each point.

Z coordinate - This option extracts the Z coordinate information of each point. If the Z coordinates are the same for each point, you may want to label the Z coordinate of the first point instead.

Label each line of points in this description

This labeling option is only active when calculation lines are defined or when the lines demarcating a grid or polygon's perimeter are visible.

- Select the Each Line tab, so that it moves to the forefront of the dialog.
- Click in the selection box adjacent to the labeling option(s) you are interested in.
- If desired, change the current font and text size.
- Click Ok.

###### Each line may be labeled with the following options:

Calculation Points Label - This option will extract the description name associated with this calculation.

Description - This option will extract the user-defined description associated with this calculation and locate it below the first point.

Line Number - This option will list the line number associated with each line at the beginning of the line.

X-Y Coordinates - This option extracts the X and Y coordinate information of the first point on each line.

Z coordinate - This option extracts the Z coordinate information of the first point on each line. If the Z coordinates are different for each point (lines of variable elevation), you may want to label the Z coordinate of each point instead.

Label each observer position in this description

This labeling option is only active when glare rating is calculated.

- Select the Observer Positions tab, so that it moves to the forefront of the dialog.
- Click in the selection box adjacent to the labeling option(s) you are interested in.
- If desired, change the current font and text size.
- Click Ok.
- Note for the Roadway Luminance calculation, the IES Observer is not label, as it is a dynamic observer relative to each point in the grid.

###### Each observer position may be labeled with the following options:

Calculation Points Label - This option will extract the description name associated with this calculation.

Observer Position Label - This option indicates each individual observer's label (e.g., Soccer Obs_1) within the calculation.

X-Y Coordinates - This option extracts the X and Y coordinate information of each observer.

Z coordinate - This option extracts the Z coordinate information of each observer.
