Graph Gauge

Overview

The Graph Gauge plots values from its input channel(s) with respect to time.

In addition to Standard Gauge Properties , the following properties may be configured:

Property	Description
Time Base	This is the width of the x axis in seconds. When a page with a historical graph gauge is first selected, the data is drawn from the left hand side of the graph (t=0). As the time progresses, the lines progress towards the right hand side of the graph. Once t = time base, the graph scrolls to the left to make more space available for drawing the lines.
Input Count	The number of lines (outputs) drawn in this graph. Changing the input count will add multiple sets of properties for each line.
Input	The output for which the line is drawn.
Colour	The colour of the line.
Minimum	Specifies the lower range of the y axis of the graph for this line. If the value of the output for this line falls below this value, the line will be drawn at the minimum value.
Maximum	Specifies the upper range of the y axis of the graph for this line. If the value of the output for this line exceeds this value, the line will be drawn at the maximum value.
