button to save it and No for not.

4.3.8 Continued testing

When open a pile file for continued test, select the profile to be
retested at first, place transducer at the start point position to be tested,
press Sample and then Retest button, input start point in continuous
test into numerical keyboard, press OK to start the test.

4.4 View switchover

You can select Bar graph, Curve graph or Wave train graph in
the General Parameters interface, and you can slide left or right in
the data graphic area to switch the view.

4.4.1 Bar graph

While switching to the view of bar graph as shown in Figure 4.15,
it displays the bar graph composed of amplitude – depth curve and
acoustic speed – depth curve of all test points in profile, and
dynamically real-time refresh in test to enable user observe the test
results of the whole profile at any time. The upper part of curve
corresponds to pile head and lower part corresponds to pile bottom.
The left side displays amplitude – depth curve, blue represents normal
amplitude in this area and red represents abnormality; the bigger the
red area is, the more serious the abnormality of amplitude is. The
right side displays acoustic speed – depth curve, blue represents
normal acoustic speed in this area and red represents abnormality; the
bigger the red area is, the more serious abnormality of the acoustic
speed is.
