Data Display Types

The Config View allows the selection of various "Display Types" for the data.

Area

This mode displays the numeric values of a PV with a staircase line.
If additional minimum/maximum information is available for the samples, that min/max envelope is indicated by a shaded area.
area

Min/max info is typically obtained by using the "optimized" request type and having a sufficiently large time range. See Request Types.

Boxes on the time axis indicate samples that have no numeric value. By clicking on them, you add a Marker which will indicate if the PV was for example "Disconnected", as shown in the next image. There may be similar boxes on other samples, where again a marker will provide the detail.

Lines

This mode displays the numeric values of a PV with a staircase line.
If additional minimum/maximum information is available for the samples, that min/max envelope is indicated by a additional lines. If there is no min/max information because we are already looking at the 'raw' data, this is the same as the "Single Line" mode described next.
area

Single Line

This mode displays the numeric values of a PV with a staircase line. It does not display additional minimum/maximum information, and should be avoided because you might miss excursions in the actual data by only viewing the averages.
area

Markers

This mode displays the numeric values of a PV with a marker. Min/max info is displayed by lines.
area

Bars

This mode displays the numeric values of a PV with bars that always start at the time axis. It does not display additional minimum/maximum information, and will only be useful in very few cases.
