13.13. Magnitude/Duration Chart Specific Information

Description Magnitude/Duration charts display the magnitude-duration relations of sags, dips,

swells, and interruptions as scatter plots. Magnitude/Duration charts differ from the

general description of charts in the following ways:

• Magnitude/Duration charts do not display the measured values, but the

duration of deviations from their nominal values.

• Magnitude/Duration charts have duration along their X-axes.

• Magnitude/Duration charts default to logarithmic X-axes.

• Magnitude/Duration charts' footers by default contain Magnitude/Duration

data as opposed to event data.

• Data Annotations in Magnitude/Duration charts use events from the sample

they are attached. An event represents a source of data and time ranges

rather than the active event.

• Special limit curves are available on the Limit Curves page of their property

dialog box.

• Magnitude/Duration charts may display more than one event marker, as

different phases during the same event may have different magnitude and

duration.

Magnitude/Duration charts' lack many settings available in other charts not

applicable to Magnitude/Duration charts.

Settings The settings for Magnitude/Duration charts are mostly identical to those of other

charts, but they do not have the Plotting or Axes pages. Specific differences can be

found on the Limit Curves page.

! Clicking an event symbol in the Magnitude/Duration chart will activate that event.
