The graph markers are used to reproduce information from the Data Editor. Notice the figure below that displays the green vertical lines. These lines are used to indicate that Zone Analysis information was introduced at the indicated points on the graph. By selecting or clearing the checkboxes, you can turn the vertical lines on or off when viewing the graph.

Description |
|---|---|
|
Measured Analysis |
Vertical lines in the associated graph marker color indicate that gas quality composition information has been introduced at the displayed point on the graph. Some Remote Terminal Units (RTUs) provide information about gas composition when the volumetric data is measured, and this is the source of measured analysis information. |
|
Zone Analysis |
Vertical lines in the associated graph marker color indicate that zone analysis information had been introduced at the displayed point on the graph. Zone analysis occurs when gas quality (GQ) information is used for multiple meters in the same area. |
|
Configuration Changes |
Vertical lines in the associated graph marker color indicate that configuration changes (changes to the properties) have taken place within the time frame displayed in the graph. |
|
Events |
Vertical lines in the associated graph marker color indicate that the GQ event information has occurred within the time frame displayed in the graph. |
