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.

Round Tacho Bitmap Gauge
The round tacho bitmap gauge allows a scaled pointer or needle to be drawn over a bitmap image of a gauge.
This allows much more eye catching graphics to be used for round gauges than could otherwise be drawn
dynamically by the display hardware.
The round tacho bitmap gauge has the following special properties:
·
Background bitmap
- the background gauge image.
·
X Centre, Y Centre
- The centre of the gauge from which the logical centre of the pointer will be drawn.
·
Centre Offset
- The number of pixels from the logical pointer centre at which the pointer will be drawn.
·
Length
- The length of the pointer.
·
Start Degrees
- The number of degrees from 6 o'clock (the zero degree position) that the starting value
of the gauge should be drawn.
·
End Degrees
- The number of degrees from 6 o'clock (the zero degree position) that the end value of the
gauge should be drawn.
The gauge default rotation is clockwise. If you want anti-clockwise operation you switch the Start Val and End
Val settings.
