9.5.19 Line Graph / Depth Graph / Indicator Graph

The line graph component emulates a traditional pen line graph plotter.

The depth graph is similar but has the lowest values at the top, and the line is

replaced with a solid area below the values.

The Indicator Graph shows the history of Indicator state.

The line graph and depth graph components plot values of the monitored

parameter over time, with the most recent values appearing on the extreme right

edge of the graph and older values appearing farther to the left.

For ranges 10 minutes and less, a red line will show the values sampled from the

database every 1 second.

For ranges 30 minutes and greater, a red line will show the average of the

samples taken from the database for the sample period shown in the following

table. Behind the red line a brown area will show the minimum and maximum

values sampled over that period.

Hovering over the graph will display a textual representation of whatever

average, minimum, or maximum value the cursor is over.

The X-axis scale, denoting the age of the data, appears at the bottom of the line

graph and the range is specified below the component. Up and down arrow

buttons are used to change the range. The following ranges are selectable:
