Displaying Mini-Graphs

When you select either Change Top or Change Bottom from the

HISTORY GRAPHS page, the selected graph is replaced by three

mini-graphs (see Figure 3–62). Each mini-graph is a reduced-size

version of a normal graph. Turn the knob to display a different graph.

The middle graph, which is highlighted, is the graph that will be

displayed full-size when you choose Select Graph. When you turn

the knob, the mini-graphs scroll either up or down depending on

which direction you turn the knob. Whether the next mini-graph

appears at the top or the bottom depends on the direction the knob

turns.

Use the mini-graph capability to view several results at once. With

mini-graphs displayed, the CTS 710 displays four graphs at the same

time. This will enable you to see relationships between different

results that might otherwise be difficult to spot.
