Specify XYZ Data Item

The Specify XYZ Data Items option is used to specify an individual XYZ data set within a data source, such as an Excel file. This option is available in the File menu. In the TableCurve 3D Explorer, it is found in the right click menu for the data source item, or if the data source is a spreadsheet file that has been expanded, it is found in the right click popup menu for each of the individual sheets.

For items without multiple sheets, this option is launched when expanding the data source for the first time.

For Excel, and other multiple worksheet data sources, this option is automatically launched when expanding any of the sheet items for the first time.

This option operates on a data source or its individual worksheets. The source must first be added to the notebook using the Import Data Source procedure. The specification applies only to the selected item in the TableCurve 3D Explorer. For spreadsheet files, this means that the X, Y, and Z columns must all come from the same sheet.

For data sources where the X, Y, and Z are defined, as in TableCurve 3D's default ASCII export format, this option is not available.

Column Selection

This option will open a column selection procedure for the X, Y, Z and optionally a weights variable. The graphical preview is helpful in assuring the correct variables have been specified.

Explorer Content

For Excel, each sheet in the XLS file will be shown with its position in the file and the name assigned to it. For other multicolumn data file types, only the position will be shown.

The sheet icon changes when expanded with data and analysis items.

The data item will display the main title for particular XYZ data set. Select the data item to view the main graph.
