Once overlays have been added to a Heat Map, they can be edited similarly to other overlays much like Histogram Overlays and 2D Plot Overlays.

 

The Overlays option controls the parameter, statistics to display, compensations, transformations, gates, and appearance of heat map overlays.

 

All heat maps have at least one overlay representing a file and well parameter to display. You can add additional overlays by any of the following methods:

 

•Right-click on the plot and select Add overlay from the pop-up menu, or

 

•Drag-and-drop file(s) from the Data List onto the plot you wish to overlay, or

 

•Drag-and-drop a plot from the layout onto the plot you wish to overlay.

 

 

You can edit overlays in one of two ways:

 

•Select the heat map and use the Format→Plot Options→Overlays command.

 

•Right-click on the map, select Format from the pop-up menu, and choose the Overlays category (Figure 32.17).

 

 

 

In the dialog, a list of all the overlays on the heat map will appear in the list box to the left . You can select one or more overlays using standard Microsoft Windows techniques, including Shift-Click and Ctrl-Click. The properties on the right pertain to the currently selected overlay(s). If multiple overlays are selected, the information will appear blank for those properties that are not identical in all selected overlays. If the properties are not blank, then they are identical for all selected overlays. Changing an option will change that property for all selected overlays. For instance, if you select three overlays and change the Gate, the Gate for all three overlays will be modified.

 

To remove an overlay from a plot, select the overlay (or multiple overlays) and press the Remove button.

To change the order of selected overlay(s) in the legend, use the blue up and down arrows ().
