Shape Gauges
Shape gauges are static gauges (i.e. have no input) that are used to draw
shapes on the screen. They have two special properties:
·
Shape
specifies the basic shape as either a Rectangle or an Ellipse.
·
Thickness
specifies the thickness of the border drawn around the shape.
Cross Hair Gauge
The Cross Hair gauge uses two inputs to move a cross hair around a box. The cross hair gauge has the following
special properties:
·
XInput
,
YInput
specify the inputs for the X and Y axes of the gauge.
·
X Minimum, Y Minimum
specify the starting values for the X and Y axes.
·
X Maximum, Y Maximum
specify the end values for the X and Y axes.
·
Cursor Size
is the size of the cross hair cursor.
·
Background graphic
can be used to specify a graphic that will be shown behind the cross hairs, This can be
used to clarify the meaning of a particular position for the cross hair.
Historical Graph
The Historical Graph gauge is used to show the trend of one or more outputs in the form of a y-t graph. The
Historical Graph gauge has the following special properties:
·
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.
