The chart shows the trend of the mean diameter during the examination. The chart is divided into three or two parts, according to the Studio modality. You have basal (1), ischemia (2) and vasodilation (3) in FMD; ischemia is missing in "Vasodilation". In offline mode, a fourth part (4) may be present if the time length of the video is greater than the sum of the basal + (ischemia) + vasodilation.
The time length of the three (two) parts is set in the Time Panel.
Using the buttons at the top right (5) you can move up or down
the chart, enlarge
or reduce
the vertical scale or restore
the default view.
