How to enter Point Data
Use: The LogPlot Point Data datasheet is used to list depths and one or more columns of numeric data to be plotted as a curve. Each Curve Column in the log design requires a separate Point Data column of values.
A Point Data datasheet can have a single column of values or multiple columns. You can have more than one Point Data datasheet in a data file. The Point Data datasheet replaces the "Curve" and "Multi-Curve" datasheets in previous versions of LogPlot.
Alternative Datasheets:
For numeric data measured at depth intervals, see the Interval Data datasheet.
For non-numeric data listed at depth points, see the Point Text datasheet.Corresponding log design component: Numeric data listed in a Point Data datasheet will be plotted on the log in the Curve Column of the same name, or in a Cross-Plot Curve column with the same name.
Corresponding RockWorks data table: P-Data
Right-Click Options: When you right-click in any of the Point Data cells, you have the following options:
Cut, Copy, Paste Insert/Append/Delete Rows Manipulate Columns Edit Data Page Name Add/Delete/Rename Columns Edit Columns and Groups Delete Data Page Move
This example illustrates how Point Data can be displayed on a log as curves with different plotting options.
Automatic:
If there is already a Curve column or a Cross-Plot Curve column in the current log design to which you will be linking the data, you can use the Data | Update Data from Log Design menu option to insert one or more Point Data datasheets in the current data file. The column names in the datasheet(s) will match the column names in the log design. The grouping of the columns in single/multiple datasheets will depend on the Group assignments in the log design.
Manual:
Select the Data | New Data Page | Point Data menu option to manually insert a Point Data datasheet.
Group Name: Type in the name to assign to the datasheet's tab or group. If you leave this blank, it will default to Name you assign below.
New Name: Type in the name to assign to the first value column in the datasheet. Because Point Data datasheets can have multiple columns, LogPlot uses the column names to match data to the items in the log design.
Click OK.
The program will add to the data file a Point Data datasheet labeled with the selected Group Name and with two blank columns: Depth, and a column with the Name you defined.
Depth: In this column you must list the depth at which the measurement was taken.
Shortcut: Right-click on any cell in the datasheet and select Fill Depth Column to fill the column with regular depth increments.
Columns 3 +: These columns are where you can list the numeric values recorded at the listed depth points.
The Column Names
The names displayed as column headers within the Point Data datasheet are used to match the data to particular Curve or Cross-Plot Curve column in the log design. For example, the data in the "Drilling Rate" column will be plotted as a curve in the "Drilling Rate" column in the log design.
Shortcut: Use the right-click options to add/rename/delete columns.
The Data Listing
To enter the actual data into the data page cells, you can use the <Tab> key to advance from cell to cell, and from the end of one row to the beginning of the next. In the column(s) you enter the quantitative values, measured at the indicated depths, to be represented on the log as a curve.
If there is no data for a depth, you may leave the cell blank. If the curve is to be plotted as a line, the line will be broken where there is no data. If the curve is to be plotted as a filled curve, then the no-data entries will simply be ignored.
Shortcut: If you already have this data in a tabular format in another application, you can copy the data there and then paste it into this datasheet using the Edit | Paste command.
