XY charts
The XY charts give a graphical representation of elements that have been prioritized according to certain criteria. The data points in XY charts are represented by customizable bubbles.
XY chart options
You can use the XY charts to:
▪ select multiple elements at a time, and edit the attributes for all of the non-selected elements
▪ display the XY chart bubbles with colors that are specified through a choice or an indicator attribute
▪ resize the bubbles, and change the bubble style
▪ display all bubbles in one size
▪ toggle the selection of elements graphically
▪ copy the chart to the clipboard without setting a login URL
▪ select or clear elements according to a certain criteria. The priority scores of the selected elements are calculated and displayed in the chart. A blue circle around an element marker indicates that the element is the one that is selected
▪ save, print, and open the chart in a new window
▪ generate reports in PDF and rich text format
▪ zoom in and zoom out to examine the elements and to identify the elements that overlap
▪ hide or show the elements
▪ get detailed information about an element by moving the mouse over the element
▪ plot titles, prefix, and icons on the chart.
Note Focal Point 6.6 and later uses a new algorithm to render the bubble size. To use the old algorithm while viewing the XY charts saved from previous releases, select Advanced > SQL and execute this query:
update projectsetting set value='false' where name='visualize.xy.new.bubble.algo'

– Default: To display all the bubbles in the same color.
– Triage: To display the bubbles in green, yellow, or red, depending on the priority of the elements.
Note The Color list displays all of the Choice attributes and Indicator attributes that are available in the view, and the default values Default and Triage. To specify that the bubble color is based on the values of a choice or an indicator attribute, select an attribute. When the Triage option is selected, bubbles appear in green, yellow, and red in the ratio 33:33:34. Green represents the top 33%, yellow represents the middle 33%, and the red represents the remaining 34% of the total elements, based on the selected criteria.
