Ribbon bar. Select the Graphs tab. In the More group, click 3D XYZ and from the menu select Wafer Plots to display the 3D Wafer Plots Startup Panel.

Classic menus. On the Graphs - 3D XYZ Graphs submenu, select Wafer Plots to display the 3D Wafer Plots Startup Panel.

Choosing a Wafer map will cause the data to be rendered as a contour plot using the Wafer fit method. The Wafer fit method displays surface data in a direct format. The collected data are organized in (x,y,z) triples. The (x,y) values specify a grid location, and the z value specifies the value at that grid point. If there are multiple values with the same (x,y) values, then all the corresponding z values are averaged so that there is just one value for every (x,y) pair. The surface is constructed by creating triangles between the individual points and then plotting these triangles with standard surface plot techniques. Only the raw data are used, (i.e., no interpolation or extrapolation is used). The resulting plot can be displayed either in 3D form as a surface or in 2D form as a contour plot.

The 3D Wafer Plots Startup Panel contains five tabs: Quick, Appearance, Categorized, Options 1, and Options 2. The following options are available regardless of which tab is selected.

OK. Click the OK button to produce the graph.

Cancel. Click the Cancel button to close the Startup Panel without creating a graph.

Options. See Options Menu for descriptions of the commands on this menu.

By Group. Click the By Group button to display the By Group specification dialog box.

Sel Cond. Click the Sel Cond button to display the Analysis/Graph Case Selection Conditions dialog box, which is used to create conditions for which cases will be included (or excluded) in the current analysis. More information is available in the case selection conditions overview and syntax summary.

Case Weights. Click the Case Weights button to display the Analysis/Graph Case Weights dialog box, which is used to adjust the contribution of individual cases to the outcome of the current analysis by "weighting" those cases in proportion to the values of a selected variable.

Graphs Gallery. Click the Graphs Gallery button to display the Statistica Graphs Gallery dialog box, which is used to easily switch among different types of graphs.

Updating. Click the Updating button to display the following menu commands:

Auto. Select Auto (the default) to disconnect the graph from the graph creation dialog box and connect the graph directly to the spreadsheet. Changes in the spreadsheet data (including selection condition changes) are immediately reflected in the graph.

Manual. Select Manual to disconnect the graph from the graph creation dialog box and connect the graph directly to the spreadsheet. Changes in the spreadsheet data are reflected in the graph only after a manual update is initiated.

Locked. Select Locked
to disconnect the graph from the graph creation dialog box and connect
the graph directly to the spreadsheet. The graph is linked to the spreadsheet,
but will not be updated when the spreadsheet data changes.

Analysis. Select Analysis to connect the graph to the graph creation dialog box and disconnect the graph from the spreadsheet. Changes to analysis options (such as fit type) will be applied to all graphs created by the analysis.

Analysis/Updating. Select Analysis/Updating to connect the graph to the graph creation dialog box and disconnect the graph from the spreadsheet. The analysis (while open) will update the graph when the spreadsheet data is changed. Once the analysis is closed, the graph will no longer update when the spreadsheet data is changed.

None. Select None to disconnect the graph from both the spreadsheet and graph creation dialog box.
