Data can be edited in two ways. In "table format" (above) the value to be edited is clicked to show either an edit box or a criteria list. In the "Select from plot" format (left) data points on the plot can be mouse clicked to display their values/criteria in the data entry/edit window, where it can be edited. The selected data point is framed with a black square. Alternatively points can be selected by using the spinner buttons.
The Data Entry/Edit window (below) can also be used for manual data entry. During manual data entry the plot area is automatically scaled after each point is entered to accommodate maximum and minimum values. At the well site a log may be displayed prior to data entry so that the relationship of depth points to lithology or other log derived information can be seen as points are obtained.
