• Further Data Filters
You have a wide range of filters available so that you can select the
data by pin or global result, testsuite, test, pin, result type, or result
number. Some of these choices are interdependent. This is fully
explained in the Results Analysis Manual, "Data Selection Options".
Bin Data Bin Display
• Count Bin column
Provides information on the number of occurrences (the count) for
each bin shown in the display.
• Bin Range data fields
Show the range occupied by each bin. In
bin 0 lies between 1.0 and1.5.
• Bin% data field
Gives the percentage of occurrences that fall into the selected bin.
100% is the full data range, not just the range that is displayed. In
Figure 158 the Bin% is 7.143%.
• Cursor panel
A narrow panel in the form of a bar running along the bottom of the
Graphic Display. The panel contains x- y coordinates of the cursor
to help you to orientate yourself in the Display area.
• Cursor Activation menu
A pull- down menu in the Cursor panel. This menu switches the
focus of the cursor between the current and overlaid bars.
Three types of graph are available for you to display statistical data, a
traditional bar chart histogram showing the population density, a
population distribution graph and a graph showing the difference
between the displayed distribution and that for a perfect gaussian
distribution. Refer to the Results Analysis Manual, "Graph Type" for
further details.
