Graph: Layout (Icon Plots)

From the Help - Animated Overviews menu, select How To: Dynamic "Data-Graphs" Link to view a multimedia presentation of the use of dynamic features to automatically update graphs.

In the Graph Options dialog tree view, select Layout (under Graph) to access the options described here. Use these options to modify the graph type of the existing Icon plot (e.g. change icons from Chernoff faces to pies). Several options are available for changing the icon type, controlling the dimensions of the array of icons that will be displayed in the icon plot, and changing the order of the variables that were originally used for making icons.

Graph Type. Select the icon type from the Graph Type list to be plotted in your modified icon plot. You can choose from the following type of graphs:

Layout. Use the Layout group to specify the n number of Rows and m number of Columns in their respective fields to display the selected type of icon (Chernoff faces, Pies etc.) in an n by m array of icons.

Standardize. Use the Standardize group to control the standardization of the values of the variables that were used in your current icon plot.

Off.  Select the Off option button to use the raw data values  to recreate the icon plot.

Variables. Select the Variables option button to standardize the values of the variables across cases to recreate the icon plot.

Cases.  Select the Cases option button to standardize the values of the variables within each icon.

Twice. The Twice option button involves a regular standardization (i.e., across cases) followed by the standardization within each case (icon).

Note: Except for unusual cases when you intend the icons to reflect the global differences in ranges of values between the selected variables, the values of the variables should be standardized once to assure the within-icon compatibility of value ranges.

Variable values mapping. Use the Variable values mapping group to control the mapping of the values of the variables that were used in your current icon plot.

Independent.  Select this option button to calculate the minimum and range separately for each variable.

Common. Select this option button to use the common minimum of all variables and the common range.

Variables order. The Variables order box displays all the variables that were used in the current icon plot. To change the order of variables, first click on the respective variable, and while holding down the mouse button "drag" the variable up or down to change the order of the variables to be used in the modified icon plot.

Original. Click the Original button to restore the order in which the variables were originally used in the icon plot.

Data update. Use the options under Data update to specify the update method applied to the graph when data change in the data file.

Automatic. Select this option button to specify that the graph data is to be updated automatically when changes are made to the data source. This will be the default setting.

Manual. Select this option button to specify that the graph data is to be updated  manually when the user explicitly requests an update of the graph data.

Locked. Select this option button to specify that the graph data is not to be updated.

Details. Click the Details button to display the Data Update Details dialog, which contains more detailed options to adjust the spreadsheet data source and variable selection used for the graph.

Don't ask before performing automatic updates on modified graph. Select this check box to specify that you don't want to be warned before the automatic update of the graph takes place.

Update on OK. If the Data update mode is set to Manual and this check box is selected, a prompt will be displayed when the source data change, and the graph will be updated when you click the OK button.

Reconnect on load. Select this option to control how the graph reloads the data from the spreadsheet. The options are Always, If spreadsheet open, Always ask, and Never.

Update spreadsheet case states. When this check box is selected, the changes of the case states (including the case labels, case excluded, case hidden, Marker color, etc.) made in the graph will be automatically updated to the spreadsheet, so that the spreadsheet that the current graph is based upon will have the same case states as in the graph.

Update Spreadsheet on OK. If this check box is selected, the current graph case states will be updated in the connected spreadsheet when the dialog is closed. If the Update Spreadsheet Case States check box is cleared, then this option can be used to perform a manual update of the spreadsheet case states.
