Bargraph Scale Tables Bargraph Scale TablesThese 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.
! 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, under the Project Tables | Log/Section Tables grouping.
Table Format
These tables have a very simple format:
Minimum and Maximum: These represent any real number values, and establish a measured value range. 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.
Size: In this column, for each z-value range, enter the size at which the bargraph is to be displayed. The size is declared in percent of the striplog column's width.
In the above example, any intervals in the selected track with very small values (0.01 - 0.02) would be displayed with bargraphs at 25% column width. Measurements from 0.02 to 0.029 would be displayed at half the width of the striplog column. Measurements from 0.029 to 0.038 would plot with bargraphs at 75% column width, and only the highest values, 0.75 and above, would display with bars that are full column width.
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.
