Graph Data

Graph data can be used to display any information that varies with depth; such as shear strength, water content, hydraulic conductivity, contaminant concentrations, volatile hydrocarbon readings, etc. There is no limit to the number of graphs that can be displayed in a borehole. Each graph can contain an unlimited number of points.

There are three types of graphs that can be used to display data. These are single graphs, double graphs, and bar graphs (histograms). The type of graph and its display format are set in the template.

In addition to the graphs above, borehole logs can contain SPT and Water Content graphs. SPT graphs are used to display the N-Values entered in the Sample Data. These graphs are generated automatically by the program. Water Content graphs are used to display water contents and Atterberg limits. The data entry for Water Content graphs is described in the Water Content section below.

Graph data can be entered and edited by:

• selecting the Graph Data submenu of the Edit menu and the selecting the name of the graph,
• clicking the right mouse button and select the Graph Data submenu from the popup menu and then selecting the name of the graph, or
• clicking the left mouse button inside the graph of the borehole log.

After performing one of the above tasks, one of the Graph forms will be displayed depending on the type of graph. If the graph type for the column is a double graph and the Edit menu or Popup menu is used to edit the graph data, only the data for the one graph selected will be displayed.

The name of the graph can be changed by clicking on the Edit Name button at the bottom of the tab. A new unique name can then be entered in the Edit Graph Name form shown below. Changing the name of the graph will affect whether the graph is displayed in the borehole log. For the graph to be displayed the template must contain a graph column with the same name.
