3D Wafer Plots

Graphical Analytic Techniques

Select Wafer Plots from the Graphs - 3D XYZ Graphs submenu to display the 3D Wafer Plots dialog. Use the options in this dialog to create three-dimensional wafer plots. This dialog contains five tabs: Quick, Appearance, Categorized, Options 1, and Options 2.

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.

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

Output. Select Output to display the Analysis/Graph Output Manager dialog, which is used to customize the current graph output management of STATISTICA.

Display. Select Display to display the Analysis/Graph Display Options dialog, which is used to customize the current graph display of STATISTICA.

Create Macro. Select Create Macro to display the New Macro dialog. When making graphs in STATISTICA, all options and output choices are automatically recorded; when you click Create Macro, the complete recording of all your actions will be translated into a STATISTICA Visual Basic program that can be run to recreate the analysis. See Macro (STATISTICA Visual Basic) Overview for further details.

Close Analysis. Select Close Analysis to close all dialogs associated with the graph. Note that results spreadsheets/graphs will not be closed, only graph dialogs will close.

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

Select Cond (Select Cases). Click the Select Cond button to display the Analysis/Graph Case Selection Conditions dialog, 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, syntax summary, and dialog description.

Case Weights. Click the Case Weights button to display the Analysis/Graph Case Weights dialog, 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 Graph Gallery button to display the STATISTICA Graphs Gallery dialog. Use the Graphs Gallery 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 and connect the graph directly to the spreadsheet. Any changes in the spreadsheet data (including selection condition changes) will be immediately reflected in the graph.

Manual. Select Manual to disconnect the graph from the graph creation dialog and connect the graph directly to the spreadsheet. Any changes in the spreadsheet data will be reflected in the graph only after a manual update is initiated.

Locked. Select Locked to disconnect the graph from the graph creation dialog 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 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 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.

OK. Click the OK button to produce the selected graph.

Cancel. Click the Cancel button to close this dialog without creating a graph.
