Use

How it's used: A Tadpole column is used to display structural readings (bearing and dip) at depth, using special "tadpole" symbols. The symbols can be fixed or variable in size and color.

How it works: As you compile your log in LogPlot, the program will read depth, bearing, and dip listings from a Tadpole datasheet or Fracture datasheet. It will plot the tadpole-shaped symbol in the Tadpole Column of the same name. The horizontal placement of the symbol is determined by the dip angle (with horizontal along the left and vertical along the right), and the orientation of the tadpole's tail is determined by the azimuth bearing. The size and color of the symbols can be fixed or variable, depending on how the data is entered.

How to…

Add a tadpole column to a log design

1. Access the Log Designer program tab.
   
2. Click in the log body design pane to make it active. (Use the Visible Sections check-boxes to show/hide the different design panes.)
   
3. Click on the Tadpoles button in the tool pane.
   
4. Position your mouse pointer where you want the left edge of the column to be, in the log body portion of the design screen, and press the left mouse button to insert it. The program will display the Tadpole Column Setup window.
   
5. Click on the Main tab to enter the tadpole-specific information:
   

   

   Name: Enter the name for this Tadpole column. Any tadpole or vector data in the LogPlot data file that is flagged with the same name will be plotted in this Tadpole column.

   Position: These coordinates determine the horizontal placement of the Tadpole column in the body of the log. The horizontal coordinates are expressed in decimal inches or centimeters relative to the left edge of the design screen. You may change the column's position by editing these values, or by widening/narrowing the column itself on the work screen (see Moving and Resizing Log Body Components). Note that the size of the symbols plotted into the Tadpole column can be either fixed or determined by size declarations in the data file.

   Frame Column: If this box is checked, the column will be bounded by a solid-line rectangle.

   Style: Choose Solid (filled circles), Circle (open circles) or Crossed Circle (open circles with an "x" inside).

   Color: Choose Column-Based if you have declared colors for each measurement in the data file. Choose Fixed to select a constant color for the tadpole symbols.

   Fixed or Default color: Click here to choose a color for the tadpoles if you've chosen Fixed, above, or for any Column-Based colors that are not declared.

   Size:

   Choose Fixed for the tadpole symbols to be a constant size. In the prompt, type in the size, in inches or centimeters, for the tadpole circles. In the example above, the tadpole circles will be 1/10th inch in width.

   Or, you can choose Value-Based if you want the tadpole symbols to be scaled based on a listing of values in the data file. If you choose this option, type into the Minimum Size prompt the size, in inches or centimeters, for the symbols with the lowest values. Type into the Maximum Size prompt the size for the symbols with the highest values listed. See the Tadpole datasheet or Fracture datasheet for details about how to set up the tadpole values.

6. Click on the Grid tab to set up any horizontal and/or vertical grid lines for the column. See Setting Up Grid Lines for more information.
   
7. To accept the displayed information, click the Apply button. You will see the Tadpole column placed in the design screen. You may continue to adjust the settings if necessary; remember to click Apply any time you want your changes applied.
   
8. To close the Tadpole Column Setup window, click the Close button.
   

Review the Settings

If you need to access the Options window you can:

• Double-click on the Tadpole Column.
• Or, right-click on the Tadpole Column and select Edit Item.
• Or, double-click on the Tadpole Column in the Item View at the bottom of the design window.
