Displaying Color Legends and Creating Tear-Away Legends
To display the color legend for a graph, select the menu item with the graph name, such as CPU
in Figure 7-11.
If you select the tear-away icon (the perforated line at the top of the drop-down menu, which is
circled in Figure 7-11), The xperf and xcxperf utilities create a tear-away (standalone) color
legend for the graph. You can move the legend next to the appropriate graph for visual correlation.

Hiding or Showing Graphs
To hide a graph, select Options→Hide/Show from the menu at the top of the display, then select
the name of the graph you want to hide. For example, you can hide the FPC (floating point)
graph by selecting Options→Hide/Show→FPC and toggling the setting for FPC.
Showing I/O Bandwidth or Utilization Rates
By default, xperf shows utilization rates for I/O devices. To show bandwidth rates in Mb/s,
select Options→I/O→Bandwidth from the menu at the top of the display.
Showing Cycles Per Instruction or Instructions Per Cycle
By default, xperf shows instructions per cycle (IPC). To show cycles per instruction (CPI), select
Options→Instructions→CPI from the menu at the top of the display.
Modifying Graph Colors and Line Widths
To change the colors or line widths for a graph, modify the X11 resource
*xperf*graph_name.colors or *xperf*graph_name.lineWidth for the graph before
starting xperf or xcxperf. To determine the graph name, enter the command xperf -graphs
or xcxperf -graphs.
For more information, see the EXTERNAL INFLUENCES section of xperf(1) or xcxperf(1).
Using xperf (Enhanced) Menu Options
Table 7-3 describes the default menu options at the top of the xperf display window. The xperf
or xcxperf utilities support these menu options when displaying enhanced node information
(the default mode for xperf).
