Bargraph Scale Tables

These tables are used to define the size of I-Data and T-Data bargraphs in 2D and 3D striplogs, as a percent of the column width, based on measured values. This can be a means of displaying background (low) values or anomalous highs in a meaningful manner.

These tables are also used to define the size of mini-diagrams in piechart maps.

! You can store multiple Bargraph Scale tables in your project database. If you assign detailed names they'll be easy to distinguish when you're selecting which to use. Bargraph Scale tables can be accessed in the Project Manger tab, under the Project Tables | Log/Section Tables grouping.

Table Format

These tables have a very simple format:

• Order: The sequential values displayed in this column are automatically assigned as you type in data. You can edit the Order values to re-order the rows.
• 
  
• Minimum and Maximum: These represent any real number values, and establish a measured value range.
  • Logs: Any depth intervals within the selected Track that you're plotting in the log column with measured values that fall within this declared range will be plotted in the log at the size declared to the right.

  • 

    Map components: If you are using the table to scale mini-diagrams in a map, any data values in the designated size column that fall within the min-max range will cause the diagrams to be plotted in the map at the size declared to the right.

    

  • Size: In this column, for each z-value range, enter the size at which the:
    (a) Striplog bargraph is to be displayed (size is declared in percent of the striplog column's width) or
    (b) Map Component is to be displayed (size is declared as a percent of the project diagonal extents).
    
    In the top example above, any intervals in the selected borehole data track with very small values (0.01 - 0.02) would be displayed with bargraphs at 25% of the striplog column width. Measurements from 0.02 to 0.03 would be displayed at half the width of the striplog column. Measurements from 0.03 to 0.04 would plot with bargraphs at 75% column width, and only the highest values, 0.4 and above, would display with bars that are full column width.
    
    In the lower example above, any samples with values in the datasheet sizing column ranging from 100 to 200 would plot the mini-piechart diagram in the map at a size of 1. Samples with column values ranging from 200 to 300 would plot the piechart diagram in the map at a size of 2, and so on.

Tip

• Use the I-Data or T-Data | Histogram option to read all of the measurements for a selected track in the project, and display different statistical groupings in a frequency plot. Use these groupings (such as mean -2 standard deviations, mean -1, etc.) as the custom bargraph scales.
