Selection of exceedence graph The exceedence graph (Figure 8 and Section 6.6) can be displayed by checking the Graph checkbox. The exceedence level is set (for the displayed wavelength range) using the Exceedence level control at the bottom of the Review screen (Figure 8). The line(s) corresponding to this level are shown if the Show checkbox is checked. If Displacement is selected as the statistic (Section 6.4.1), horizontal dotted lines are shown at +/- the selected Exceedence level. If any of the other three statistics is selected, a single horizontal line is shown at the selected Exceedence level. If the exceedence graph is enabled, a vertical line is shown at the Exceedence level. A horizontal dotted line is drawn on the exceedence graph, if displayed, at the level displayed on the % control. As an alternative to the exceedence graph, a Grinding or Exceedence Report (Section 6.9) can be displayed by checking the Report checkbox at the bottom of the Review screen (Figure 8). Either the graph or the report (but not both) can be displayed at any one time.
